1.1 INTRODUCTION

This Recovery Plan provides summary information on the White Shark, including biology, habitat, distribution and historical and current threats to its recovery.

The Plan has been developed in accordance with the Guidelines for the Compilation of Recovery Plans under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). It therefore sets out the recovery objectives, actions required to achieve those objectives, performance indicators, as well as identifying those responsible for implementing the actions and the timeframes involved. The Plan also identifies an aggregated costing for the recovery of the White Shark.

Additional information is provided such as guidelines for decision-makers and tools to assist the implementation of the Plan.

A comprehensive review of the biological information and current behavioural and ecological knowledge of the White Shark is provided in an appendix attached to this Plan.

1.2 CONTEXTUAL INFORMATION

1.2.1 The Region Covered

This Plan covers all Australian waters in which the White Shark is found.

The White Shark is widely distributed, and located throughout temperate and sub-tropical regions in the northern and southern hemispheres. In Australia, its range extends primarily from Moreton Bay in southern Queensland, with at least one record as far north as Mackay, (Paterson, 1990:154) around the southern coastline and to North West Cape in Western Australia (Bruce 1995).

1.2.2 Conservation Status, Historical and current size of Population

The White Shark, Carcharodon carcharias, is also known in Australia as the Great White Shark or White Pointer and is fully protected in Commonwealth waters under the EPBC Act where it is listed as a vulnerable species. The listing of the White Shark as vulnerable was based on a number of factors, including evidence of a declining population, its life history characteristics (long lived and low levels of reproduction), limited local distribution and abundance and at the time of listing, and still being under pressure from the Australian commercial fishing industry.

The White Shark is also fully protected in the coastal waters of Tasmania, South Australia, Victoria and Western Australia; and protected in the coastal waters of New South Wales and Queensland with exemptions made for beach meshing.

Internationally White Sharks are listed as ‘vulnerable’ on the IUCN Red List of threatened species (IUCN 2000) as well as protected in South Africa (1991), Namibia, the Maldives, Florida and California (US) and Malta.

There is little historical information on population estimates for the White Shark. The current population status of White Sharks in Australia is difficult to assess due to:

• poorly known stock structure and movement patterns;
• paucity of information on captures across all fishing sectors;
• ambiguities in available data;
• shortage of verified data; and
• lack of suitable indices of abundance or population monitoring programs.

Available data sets suggest a decline in abundance and size of White Sharks in some areas (Reid and Krogh 1992). These data include beach meshing records for New South Wales and Queensland, game fishing records from New South Wales and South Australia, and anecdotal sighting frequencies by tourism operators and divers in South Australia which all report declining catches and sightings (Bruce 1995). This interpretation is complicated by a marked interannual variability that may not be related to population size (Bruce 1995, Fox & Taylor pers comm. in Strong et al. 1992) as well as other factors such as changes in shark meshing regimes or decreased fishing effort (Peperell 1992). There are also competing claims that the number of White Sharks has increased in certain areas (for examplejuvenile White Sharks in some areas of Victorian coastal waters). Despite the inadequacies in the available data, there appears to be an overall, long-term decline in abundance of White Sharks in Australian waters

There are similarly few data sets from which an assessment for worldwide populations of White Sharks can be made. Game fishing data from the east-coast of North America indicate declines in the proportion of White Sharks taken relative to other shark species caught, similar to that reported off eastern Australia by Pepperell (1992). Casey and Pratt (1985) reported a drop in the ratio of White Sharks to all other sharks captured from 1:67 in 1965 to 1:210 in 1983 for the mid-Atlantic Bight.

Cliff et al. (1996a) reported marked interannual variability in the capture rates of White Sharks in the South African beach meshing program, with a cyclical period of 4-6 years. They also reported a significant decline in White Shark captures between 1973 and 1993.

1.2.4 Relevance to Indigenous Australians

There are no known significant interactions between Aborigines and the White Shark.

1.2.5 Relationship between the Plan and other Planning Processes

Comparable regulations or actions that reflect actions within this Plan have been introduced in South Australia, Victoria, Tasmania, New South Wales and Western Australia. The following table provides a summary explanation of the legislation underpinning the protection of the White Shark in relevant Australian jurisdictions.

Table 1. Legislation that protects White Sharks or identifies their status as needing particular conservation action in Australia.

Table adapted from work compiled by CSIRO Marine Research

1.2.6 Major benefits to other native species or communities

Section 270 of the EPBC Act requires that this Plan specifies any major benefits to species or ecological communities other than White Sharks that may be derived from actions taken in accordance with this Plan. Conservation measures to benefit White Sharks and their habitat may benefit inshore marine communities. In addition, by managing fishery bycatch and researching alternatives to shark meshing, these threats to other species, such as whales, dolphins, marine turtles, pelagic rays, some fish species and other sharks may be reduced,. Some of these species are also threatened or are uncommon. Marine communities may also benefit from any marine protected areas that may be established to protect White Sharks and conversely White Sharks may benefit from marine protected areas established within their range.

1.3 HABITAT CRITICAL TO THE SURVIVAL OF THE SPECIES

The EPBC Act specifies that recovery plans should identify the habitats that are critical to the survival of the species or community concerned and the actions needed to protect those habitats (S270 (2)(d).

To date there is little solid information or research findings upon which to identify habitat critical to the survival of the White Shark. An important early step towards the identification of habitat critical for the survival of the White Shark would be the identification of the characteristics of habitat critical to the survival of White Shark. Also as White Sharks appear to move through developmental habitats as they grow, the identification of critical habitat for White Sharks may be difficult given the unknown nature of their developmental needs at various life stages.

A full description of White Shark habitat can be found at Appendix B.

1.4 OVERVIEW OF THREATS AND ISSUES

There are a number of sources of mortality (other than natural mortality) of White Sharks in Australian waters. The most predominant of these are dealt with below.

1.4.1 Commercial Fishing

Despite not being commercially targeted, White Sharks are caught as bycatch on long-lines and in nets of professional fishers and in fin fish farm cages such as tuna farms. This is currently suspected to be the largest cause of mortality. The actual rate of capture of White Sharks by commercial fishers is difficult to assess and has not yet been quantified. This is because captures are not usually recorded, and in many cases, captured sharks are either not landed intact or not landed at all. Estimates of annual capture, based on anecdotal reports, range from less than 10 to 100 per annum in South Australia and 100 to 440 per annum for all fisheries (recreational and commercial combined) in Australian waters.

Further investigations are needed to quantify the capture of White Sharks from commercial fishing in each of the fisheries and establish the impact the commercial fishing industry has on the Australian population of White Sharks. It is necessary for commercial fisheries managers to assist industry to improve reporting of the take or interaction with White Sharks.

A full description of this threat can be found at Appendix C

1.4.2 Recreational Fishing

Prior to the implementation of protective legislation, game fishing for White Sharks was carried out mainly in South Australia, Queensland and New South Wales, but also in Victoria and Western Australia. Game fishing in South Australia for White Sharks was at its height in the 1950s. Between 1980 and 1990 White Sharks were also tagged and released although the survival rate of these sharks is not known. Further research in New South Wales using game fishing data for New South Wales calculated that the ratio of White Sharks to all shark species caught had changed from 1:22 in the 1960s to 1:38 in the 1970s and 1:651 in the 1980s. In the 1990s, capture of White Shark by game fishers off the coast of New South Wales was 13:2103 or 1:162 (Chan 2001). Prior targeting and removal of the largest and oldest of the population by game fishers would have had the effect of removing the most reproductively productive members of the population.

Game fishing groups have expressed a keen interest in accessing White Sharks for tag-release since the species was protected. Other groups have raised concerns that capture induced mortality or sublethal stress from tag-release activities may be unacceptably high. Issues of cryptic mortality, sublethal effect and scientific benefits also need to be addressed.

Other recreational fishers still occasionally capture White Sharks (for example in gill nets in Tasmanian waters and while fishing for other sharks in Western Australia, Victoria and New South Wales, and fishing for snapper in South Australia and Victoria). In some cases small White Sharks are mistakenly identified as other species (for example mako sharks).

A full description of this threat can be found at Appendix C.

1.4.3 Shark Control Activities

Shark control activities in Australia include beach meshing and drumlines, which most often kill the captured shark. Some non-lethal methods that are being trialed include using electrical fields to repel sharks but these practical trials have encountered many logistical problems. White Sharks are a target species in control activities but other non-target species are impacted by shark meshing such as turtles, dugongs and dolphins.

Queensland and New South Wales are the only two States to employ protective beach meshing. There are currently a total of 49 meshed beaches set offshore between Newcastle and Wollongong in New South Wales (approximately 200 km of coastline). In Queensland, a mixture of baited drumlines and nets are used. Drumlines consist of a marker buoy and float supporting a trace and baited hooks anchored to the bottom, and are intended to target dangerous species of sharks and reduce the bycatch of non-target species.

Shark meshing effort has increased over time. If the catch per unit effort (CPUE) equates to some measure of abundance then there has been a significant decline in White Shark abundance in both programs. The average size of White Sharks caught in New South Wales meshing operations has also declined over the period, though this is apparently not evidenced in the Queensland data. The degree to which beach meshing is impacting on White Shark populations is unknown although the decline in captures suggests it is significant.

A full description of this threat can be found at Appendix C.

1.4.4 Trade

The killing of White Sharks for trade targets two main areas – trade in trophy products such as jaws, and teeth and the trade in fins for food items such as ‘shark fin soup’. Increasing demand for White Shark products particularly fins, jaws, and teeth, has increased their value. Recent reports have been made identifying values of up to $50 000 paid for jaws from South Africa and $600 for individual teeth, despite their current protection there. Illegal trade in White Shark products may be a threat to the Australian population of White Sharks.

There are several commercial fisheries in Australia that frequently take shark fins as by product. Dried shark fin can attract a high price on Asian markets. The high market value for shark fins is leading to a high level of targeting of sharks that may be unsustainable. There is a growing acceptance that shark finning is both wasteful, when fins are removed and the carcass is discarded. This method is also a possible inducement to fishers to actively target sharks.

A full description of this threat can be found at Appendix C.

1.4.5 Tourism

Tourism does not pose a direct threat to White Sharks but through indirect means may limit the recovery of the population by altering the behaviour of the animal.

Both shark cage diving and shark boat tours are dependent on attracting sharks to an area by berleying (also known as ‘chumming’). Berleying involves releasing a mixture of fish oil and/or animal products into the water at regular time intervals to develop a slick to attract sharks in the vicinity. The use of berley may encourage White Sharks to appear or stay longer in a location that they would not normally visit, and there is the possibility that sharks will become habituated and begin to associate humans and boats with food. In addition the effect of berleying in areas adjacent to seal/sea lion colonies may result in higher mortality of seals/sea lions as a consequence of the increase presence of White Sharks. Tourism activities also raise the issue of disturbance to White Sharks and their prey. The effect of watercraft and human activities on sharks and marine mammals in the vicinity needs to be established.

However, it should be noted that some tourism activities in particular cage diving are contributing to data collection for further research

A full description of this threat can be found at Appendix C.

1.4.6 Tag and Release

Tag and release if not undertaken with care or without knowledge can contribute to White Sharks dying through the stress of being captured. Tag and release programs can provide information on movement patterns, site fidelity, growth, population estimates and mortality estimates. Tag and release programs must be assessed against the risk to the individual sharks and the benefit of the knowledge it is proposed to gain.

A full description of this threat can be found at Appendix C.

Part 2. RECOVERY OBJECTIVES

Section 270 of the EPBC Act specifies the content of a Recovery Plan.

2.1 Recovery Plan Objective:

The overall Recovery Plan objectives are:

‘To recover White Shark numbers in Australian waters, to a level that will see the species removed from the schedules of the Environmental Protection and Biodiversity Conservation Act 1999.

To implement the actions that lead to eventual removal of the species from the threatened species schedules of Environmental Protection and Biodiversity Conservation Act 1999.’

2.1.1 Specific Objectives:

The specific objectives of this Plan are to:

1. monitor and reduce the impact of commercial fishing on White Sharks;
2. investigate and evaluate the impact of recreational fishing on White Sharks;
3. monitor and reduce the impact of shark control activities on White Sharks;
4. identify and manage the impact of tourism on White Sharks;
5. monitor and reduce the impact of trade in White Shark products;
6. develop research programs toward the conservation of White Sharks;
7. identify habitat critical to the survival of White Sharks and establish suitable protection of this habitat from threatening activities;
8. promote community education and awareness in relation to White Sharks; and

1.1 INTRODUCTION

This Recovery Plan provides summary information on the White Shark, including biology, habitat, distribution and historical and current threats to its recovery.

The Plan has been developed in accordance with the Guidelines for the Compilation of Recovery Plans under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). It therefore sets out the recovery objectives, actions required to achieve those objectives, performance indicators, as well as identifying those responsible for implementing the actions and the timeframes involved. The Plan also identifies an aggregated costing for the recovery of the White Shark.

Additional information is provided such as guidelines for decision-makers and tools to assist the implementation of the Plan.

A comprehensive review of the biological information and current behavioural and ecological knowledge of the White Shark is provided in an appendix attached to this Plan.

1.2 CONTEXTUAL INFORMATION

1.2.1 The Region Covered

This Plan covers all Australian waters in which the White Shark is found.

The White Shark is widely distributed, and located throughout temperate and sub-tropical regions in the northern and southern hemispheres. In Australia, its range extends primarily from Moreton Bay in southern Queensland, with at least one record as far north as Mackay, (Paterson, 1990:154) around the southern coastline and to North West Cape in Western Australia (Bruce 1995).

1.2.2 Conservation Status, Historical and current size of Population

The White Shark, Carcharodon carcharias, is also known in Australia as the Great White Shark or White Pointer and is fully protected in Commonwealth waters under the EPBC Act where it is listed as a vulnerable species. The listing of the White Shark as vulnerable was based on a number of factors, including evidence of a declining population, its life history characteristics (long lived and low levels of reproduction), limited local distribution and abundance and at the time of listing, and still being under pressure from the Australian commercial fishing industry.

The White Shark is also fully protected in the coastal waters of Tasmania, South Australia, Victoria and Western Australia; and protected in the coastal waters of New South Wales and Queensland with exemptions made for beach meshing.

Internationally White Sharks are listed as ‘vulnerable’ on the IUCN Red List of threatened species (IUCN 2000) as well as protected in South Africa (1991), Namibia, the Maldives, Florida and California (US) and Malta.

There is little historical information on population estimates for the White Shark. The current population status of White Sharks in Australia is difficult to assess due to:

• poorly known stock structure and movement patterns;
• paucity of information on captures across all fishing sectors;
• ambiguities in available data;
• shortage of verified data; and
• lack of suitable indices of abundance or population monitoring programs.

Available data sets suggest a decline in abundance and size of White Sharks in some areas (Reid and Krogh 1992). These data include beach meshing records for New South Wales and Queensland, game fishing records from New South Wales and South Australia, and anecdotal sighting frequencies by tourism operators and divers in South Australia which all report declining catches and sightings (Bruce 1995). This interpretation is complicated by a marked interannual variability that may not be related to population size (Bruce 1995, Fox & Taylor pers comm. in Strong et al. 1992) as well as other factors such as changes in shark meshing regimes or decreased fishing effort (Peperell 1992). There are also competing claims that the number of White Sharks has increased in certain areas (for examplejuvenile White Sharks in some areas of Victorian coastal waters). Despite the inadequacies in the available data, there appears to be an overall, long-term decline in abundance of White Sharks in Australian waters

There are similarly few data sets from which an assessment for worldwide populations of White Sharks can be made. Game fishing data from the east-coast of North America indicate declines in the proportion of White Sharks taken relative to other shark species caught, similar to that reported off eastern Australia by Pepperell (1992). Casey and Pratt (1985) reported a drop in the ratio of White Sharks to all other sharks captured from 1:67 in 1965 to 1:210 in 1983 for the mid-Atlantic Bight.

Cliff et al. (1996a) reported marked interannual variability in the capture rates of White Sharks in the South African beach meshing program, with a cyclical period of 4-6 years. They also reported a significant decline in White Shark captures between 1973 and 1993.

1.2.4 Relevance to Indigenous Australians

There are no known significant interactions between Aborigines and the White Shark.

1.2.5 Relationship between the Plan and other Planning Processes

Comparable regulations or actions that reflect actions within this Plan have been introduced in South Australia, Victoria, Tasmania, New South Wales and Western Australia. The following table provides a summary explanation of the legislation underpinning the protection of the White Shark in relevant Australian jurisdictions.

Table 1. Legislation that protects White Sharks or identifies their status as needing particular conservation action in Australia.

Table adapted from work compiled by CSIRO Marine Research

1.2.6 Major benefits to other native species or communities

Section 270 of the EPBC Act requires that this Plan specifies any major benefits to species or ecological communities other than White Sharks that may be derived from actions taken in accordance with this Plan. Conservation measures to benefit White Sharks and their habitat may benefit inshore marine communities. In addition, by managing fishery bycatch and researching alternatives to shark meshing, these threats to other species, such as whales, dolphins, marine turtles, pelagic rays, some fish species and other sharks may be reduced,. Some of these species are also threatened or are uncommon. Marine communities may also benefit from any marine protected areas that may be established to protect White Sharks and conversely White Sharks may benefit from marine protected areas established within their range.

1.3 HABITAT CRITICAL TO THE SURVIVAL OF THE SPECIES

The EPBC Act specifies that recovery plans should identify the habitats that are critical to the survival of the species or community concerned and the actions needed to protect those habitats (S270 (2)(d).

To date there is little solid information or research findings upon which to identify habitat critical to the survival of the White Shark. An important early step towards the identification of habitat critical for the survival of the White Shark would be the identification of the characteristics of habitat critical to the survival of White Shark. Also as White Sharks appear to move through developmental habitats as they grow, the identification of critical habitat for White Sharks may be difficult given the unknown nature of their developmental needs at various life stages.

A full description of White Shark habitat can be found at Appendix B.

1.4 OVERVIEW OF THREATS AND ISSUES

There are a number of sources of mortality (other than natural mortality) of White Sharks in Australian waters. The most predominant of these are dealt with below.

1.4.1 Commercial Fishing

Despite not being commercially targeted, White Sharks are caught as bycatch on long-lines and in nets of professional fishers and in fin fish farm cages such as tuna farms. This is currently suspected to be the largest cause of mortality. The actual rate of capture of White Sharks by commercial fishers is difficult to assess and has not yet been quantified. This is because captures are not usually recorded, and in many cases, captured sharks are either not landed intact or not landed at all. Estimates of annual capture, based on anecdotal reports, range from less than 10 to 100 per annum in South Australia and 100 to 440 per annum for all fisheries (recreational and commercial combined) in Australian waters.

Further investigations are needed to quantify the capture of White Sharks from commercial fishing in each of the fisheries and establish the impact the commercial fishing industry has on the Australian population of White Sharks. It is necessary for commercial fisheries managers to assist industry to improve reporting of the take or interaction with White Sharks.

A full description of this threat can be found at Appendix C

1.4.2 Recreational Fishing

Prior to the implementation of protective legislation, game fishing for White Sharks was carried out mainly in South Australia, Queensland and New South Wales, but also in Victoria and Western Australia. Game fishing in South Australia for White Sharks was at its height in the 1950s. Between 1980 and 1990 White Sharks were also tagged and released although the survival rate of these sharks is not known. Further research in New South Wales using game fishing data for New South Wales calculated that the ratio of White Sharks to all shark species caught had changed from 1:22 in the 1960s to 1:38 in the 1970s and 1:651 in the 1980s. In the 1990s, capture of White Shark by game fishers off the coast of New South Wales was 13:2103 or 1:162 (Chan 2001). Prior targeting and removal of the largest and oldest of the population by game fishers would have had the effect of removing the most reproductively productive members of the population.

Game fishing groups have expressed a keen interest in accessing White Sharks for tag-release since the species was protected. Other groups have raised concerns that capture induced mortality or sublethal stress from tag-release activities may be unacceptably high. Issues of cryptic mortality, sublethal effect and scientific benefits also need to be addressed.

Other recreational fishers still occasionally capture White Sharks (for example in gill nets in Tasmanian waters and while fishing for other sharks in Western Australia, Victoria and New South Wales, and fishing for snapper in South Australia and Victoria). In some cases small White Sharks are mistakenly identified as other species (for example mako sharks).

A full description of this threat can be found at Appendix C.

1.4.3 Shark Control Activities

Shark control activities in Australia include beach meshing and drumlines, which most often kill the captured shark. Some non-lethal methods that are being trialed include using electrical fields to repel sharks but these practical trials have encountered many logistical problems. White Sharks are a target species in control activities but other non-target species are impacted by shark meshing such as turtles, dugongs and dolphins.

Queensland and New South Wales are the only two States to employ protective beach meshing. There are currently a total of 49 meshed beaches set offshore between Newcastle and Wollongong in New South Wales (approximately 200 km of coastline). In Queensland, a mixture of baited drumlines and nets are used. Drumlines consist of a marker buoy and float supporting a trace and baited hooks anchored to the bottom, and are intended to target dangerous species of sharks and reduce the bycatch of non-target species.

Shark meshing effort has increased over time. If the catch per unit effort (CPUE) equates to some measure of abundance then there has been a significant decline in White Shark abundance in both programs. The average size of White Sharks caught in New South Wales meshing operations has also declined over the period, though this is apparently not evidenced in the Queensland data. The degree to which beach meshing is impacting on White Shark populations is unknown although the decline in captures suggests it is significant.

A full description of this threat can be found at Appendix C.

1.4.4 Trade

The killing of White Sharks for trade targets two main areas – trade in trophy products such as jaws, and teeth and the trade in fins for food items such as ‘shark fin soup’. Increasing demand for White Shark products particularly fins, jaws, and teeth, has increased their value. Recent reports have been made identifying values of up to $50 000 paid for jaws from South Africa and $600 for individual teeth, despite their current protection there. Illegal trade in White Shark products may be a threat to the Australian population of White Sharks.

There are several commercial fisheries in Australia that frequently take shark fins as by product. Dried shark fin can attract a high price on Asian markets. The high market value for shark fins is leading to a high level of targeting of sharks that may be unsustainable. There is a growing acceptance that shark finning is both wasteful, when fins are removed and the carcass is discarded. This method is also a possible inducement to fishers to actively target sharks.

A full description of this threat can be found at Appendix C.

1.4.5 Tourism

Tourism does not pose a direct threat to White Sharks but through indirect means may limit the recovery of the population by altering the behaviour of the animal.

Both shark cage diving and shark boat tours are dependent on attracting sharks to an area by berleying (also known as ‘chumming’). Berleying involves releasing a mixture of fish oil and/or animal products into the water at regular time intervals to develop a slick to attract sharks in the vicinity. The use of berley may encourage White Sharks to appear or stay longer in a location that they would not normally visit, and there is the possibility that sharks will become habituated and begin to associate humans and boats with food. In addition the effect of berleying in areas adjacent to seal/sea lion colonies may result in higher mortality of seals/sea lions as a consequence of the increase presence of White Sharks. Tourism activities also raise the issue of disturbance to White Sharks and their prey. The effect of watercraft and human activities on sharks and marine mammals in the vicinity needs to be established.

However, it should be noted that some tourism activities in particular cage diving are contributing to data collection for further research

A full description of this threat can be found at Appendix C.

1.4.6 Tag and Release

Tag and release if not undertaken with care or without knowledge can contribute to White Sharks dying through the stress of being captured. Tag and release programs can provide information on movement patterns, site fidelity, growth, population estimates and mortality estimates. Tag and release programs must be assessed against the risk to the individual sharks and the benefit of the knowledge it is proposed to gain.

A full description of this threat can be found at Appendix C.

PART 1

1.1 INTRODUCTION

This Recovery Plan provides summary information on the White Shark, including biology, habitat, distribution and historical and current threats to its recovery.

The Plan has been developed in accordance with the Guidelines for the Compilation of Recovery Plans under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). It therefore sets out the recovery objectives, actions required to achieve those objectives, performance indicators, as well as identifying those responsible for implementing the actions and the timeframes involved. The Plan also identifies an aggregated costing for the recovery of the White Shark.

Additional information is provided such as guidelines for decision-makers and tools to assist the implementation of the Plan.

A comprehensive review of the biological information and current behavioural and ecological knowledge of the White Shark is provided in an appendix attached to this Plan.

1.2 CONTEXTUAL INFORMATION

1.2.1 The Region Covered

This Plan covers all Australian waters in which the White Shark is found.

The White Shark is widely distributed, and located throughout temperate and sub-tropical regions in the northern and southern hemispheres. In Australia, its range extends primarily from Moreton Bay in southern Queensland, with at least one record as far north as Mackay, (Paterson, 1990:154) around the southern coastline and to North West Cape in Western Australia (Bruce 1995).

1.2.2 Conservation Status, Historical and current size of Population

The White Shark, Carcharodon carcharias, is also known in Australia as the Great White Shark or White Pointer and is fully protected in Commonwealth waters under the EPBC Act where it is listed as a vulnerable species. The listing of the White Shark as vulnerable was based on a number of factors, including evidence of a declining population, its life history characteristics (long lived and low levels of reproduction), limited local distribution and abundance and at the time of listing, and still being under pressure from the Australian commercial fishing industry.

The White Shark is also fully protected in the coastal waters of Tasmania, South Australia, Victoria and Western Australia; and protected in the coastal waters of New South Wales and Queensland with exemptions made for beach meshing.

Internationally White Sharks are listed as ‘vulnerable’ on the IUCN Red List of threatened species (IUCN 2000) as well as protected in South Africa (1991), Namibia, the Maldives, Florida and California (US) and Malta.

There is little historical information on population estimates for the White Shark. The current population status of White Sharks in Australia is difficult to assess due to:

• poorly known stock structure and movement patterns;
• paucity of information on captures across all fishing sectors;
• ambiguities in available data;
• shortage of verified data; and
• lack of suitable indices of abundance or population monitoring programs.

Available data sets suggest a decline in abundance and size of White Sharks in some areas (Reid and Krogh 1992). These data include beach meshing records for New South Wales and Queensland, game fishing records from New South Wales and South Australia, and anecdotal sighting frequencies by tourism operators and divers in South Australia which all report declining catches and sightings (Bruce 1995). This interpretation is complicated by a marked interannual variability that may not be related to population size (Bruce 1995, Fox & Taylor pers comm. in Strong et al. 1992) as well as other factors such as changes in shark meshing regimes or decreased fishing effort (Peperell 1992). There are also competing claims that the number of White Sharks has increased in certain areas (for examplejuvenile White Sharks in some areas of Victorian coastal waters). Despite the inadequacies in the available data, there appears to be an overall, long-term decline in abundance of White Sharks in Australian waters

There are similarly few data sets from which an assessment for worldwide populations of White Sharks can be made. Game fishing data from the east-coast of North America indicate declines in the proportion of White Sharks taken relative to other shark species caught, similar to that reported off eastern Australia by Pepperell (1992). Casey and Pratt (1985) reported a drop in the ratio of White Sharks to all other sharks captured from 1:67 in 1965 to 1:210 in 1983 for the mid-Atlantic Bight.

Cliff et al. (1996a) reported marked interannual variability in the capture rates of White Sharks in the South African beach meshing program, with a cyclical period of 4-6 years. They also reported a significant decline in White Shark captures between 1973 and 1993.

1.2.4 Relevance to Indigenous Australians

There are no known significant interactions between Aborigines and the White Shark.

1.2.5 Relationship between the Plan and other Planning Processes

Comparable regulations or actions that reflect actions within this Plan have been introduced in South Australia, Victoria, Tasmania, New South Wales and Western Australia. The following table provides a summary explanation of the legislation underpinning the protection of the White Shark in relevant Australian jurisdictions.

Table 1. Legislation that protects White Sharks or identifies their status as needing particular conservation action in Australia.

Table adapted from work compiled by CSIRO Marine Research

1.2.6 Major benefits to other native species or communities

Section 270 of the EPBC Act requires that this Plan specifies any major benefits to species or ecological communities other than White Sharks that may be derived from actions taken in accordance with this Plan. Conservation measures to benefit White Sharks and their habitat may benefit inshore marine communities. In addition, by managing fishery bycatch and researching alternatives to shark meshing, these threats to other species, such as whales, dolphins, marine turtles, pelagic rays, some fish species and other sharks may be reduced,. Some of these species are also threatened or are uncommon. Marine communities may also benefit from any marine protected areas that may be established to protect White Sharks and conversely White Sharks may benefit from marine protected areas established within their range.

1.3 HABITAT CRITICAL TO THE SURVIVAL OF THE SPECIES

The EPBC Act specifies that recovery plans should identify the habitats that are critical to the survival of the species or community concerned and the actions needed to protect those habitats (S270 (2)(d).

To date there is little solid information or research findings upon which to identify habitat critical to the survival of the White Shark. An important early step towards the identification of habitat critical for the survival of the White Shark would be the identification of the characteristics of habitat critical to the survival of White Shark. Also as White Sharks appear to move through developmental habitats as they grow, the identification of critical habitat for White Sharks may be difficult given the unknown nature of their developmental needs at various life stages.

A full description of White Shark habitat can be found at Appendix B.

1.4 OVERVIEW OF THREATS AND ISSUES

There are a number of sources of mortality (other than natural mortality) of White Sharks in Australian waters. The most predominant of these are dealt with below.

1.4.1 Commercial Fishing

Despite not being commercially targeted, White Sharks are caught as bycatch on long-lines and in nets of professional fishers and in fin fish farm cages such as tuna farms. This is currently suspected to be the largest cause of mortality. The actual rate of capture of White Sharks by commercial fishers is difficult to assess and has not yet been quantified. This is because captures are not usually recorded, and in many cases, captured sharks are either not landed intact or not landed at all. Estimates of annual capture, based on anecdotal reports, range from less than 10 to 100 per annum in South Australia and 100 to 440 per annum for all fisheries (recreational and commercial combined) in Australian waters.

Further investigations are needed to quantify the capture of White Sharks from commercial fishing in each of the fisheries and establish the impact the commercial fishing industry has on the Australian population of White Sharks. It is necessary for commercial fisheries managers to assist industry to improve reporting of the take or interaction with White Sharks.

A full description of this threat can be found at Appendix C

1.4.2 Recreational Fishing

Prior to the implementation of protective legislation, game fishing for White Sharks was carried out mainly in South Australia, Queensland and New South Wales, but also in Victoria and Western Australia. Game fishing in South Australia for White Sharks was at its height in the 1950s. Between 1980 and 1990 White Sharks were also tagged and released although the survival rate of these sharks is not known. Further research in New South Wales using game fishing data for New South Wales calculated that the ratio of White Sharks to all shark species caught had changed from 1:22 in the 1960s to 1:38 in the 1970s and 1:651 in the 1980s. In the 1990s, capture of White Shark by game fishers off the coast of New South Wales was 13:2103 or 1:162 (Chan 2001). Prior targeting and removal of the largest and oldest of the population by game fishers would have had the effect of removing the most reproductively productive members of the population.

Game fishing groups have expressed a keen interest in accessing White Sharks for tag-release since the species was protected. Other groups have raised concerns that capture induced mortality or sublethal stress from tag-release activities may be unacceptably high. Issues of cryptic mortality, sublethal effect and scientific benefits also need to be addressed.

Other recreational fishers still occasionally capture White Sharks (for example in gill nets in Tasmanian waters and while fishing for other sharks in Western Australia, Victoria and New South Wales, and fishing for snapper in South Australia and Victoria). In some cases small White Sharks are mistakenly identified as other species (for example mako sharks).

A full description of this threat can be found at Appendix C.

1.4.3 Shark Control Activities

Shark control activities in Australia include beach meshing and drumlines, which most often kill the captured shark. Some non-lethal methods that are being trialed include using electrical fields to repel sharks but these practical trials have encountered many logistical problems. White Sharks are a target species in control activities but other non-target species are impacted by shark meshing such as turtles, dugongs and dolphins.

Queensland and New South Wales are the only two States to employ protective beach meshing. There are currently a total of 49 meshed beaches set offshore between Newcastle and Wollongong in New South Wales (approximately 200 km of coastline). In Queensland, a mixture of baited drumlines and nets are used. Drumlines consist of a marker buoy and float supporting a trace and baited hooks anchored to the bottom, and are intended to target dangerous species of sharks and reduce the bycatch of non-target species.

Shark meshing effort has increased over time. If the catch per unit effort (CPUE) equates to some measure of abundance then there has been a significant decline in White Shark abundance in both programs. The average size of White Sharks caught in New South Wales meshing operations has also declined over the period, though this is apparently not evidenced in the Queensland data. The degree to which beach meshing is impacting on White Shark populations is unknown although the decline in captures suggests it is significant.

A full description of this threat can be found at Appendix C.

1.4.4 Trade

The killing of White Sharks for trade targets two main areas – trade in trophy products such as jaws, and teeth and the trade in fins for food items such as ‘shark fin soup’. Increasing demand for White Shark products particularly fins, jaws, and teeth, has increased their value. Recent reports have been made identifying values of up to $50 000 paid for jaws from South Africa and $600 for individual teeth, despite their current protection there. Illegal trade in White Shark products may be a threat to the Australian population of White Sharks.

There are several commercial fisheries in Australia that frequently take shark fins as by product. Dried shark fin can attract a high price on Asian markets. The high market value for shark fins is leading to a high level of targeting of sharks that may be unsustainable. There is a growing acceptance that shark finning is both wasteful, when fins are removed and the carcass is discarded. This method is also a possible inducement to fishers to actively target sharks.

A full description of this threat can be found at Appendix C.

1.4.5 Tourism

Tourism does not pose a direct threat to White Sharks but through indirect means may limit the recovery of the population by altering the behaviour of the animal.

Both shark cage diving and shark boat tours are dependent on attracting sharks to an area by berleying (also known as ‘chumming’). Berleying involves releasing a mixture of fish oil and/or animal products into the water at regular time intervals to develop a slick to attract sharks in the vicinity. The use of berley may encourage White Sharks to appear or stay longer in a location that they would not normally visit, and there is the possibility that sharks will become habituated and begin to associate humans and boats with food. In addition the effect of berleying in areas adjacent to seal/sea lion colonies may result in higher mortality of seals/sea lions as a consequence of the increase presence of White Sharks. Tourism activities also raise the issue of disturbance to White Sharks and their prey. The effect of watercraft and human activities on sharks and marine mammals in the vicinity needs to be established.

However, it should be noted that some tourism activities in particular cage diving are contributing to data collection for further research

A full description of this threat can be found at Appendix C.

1.4.6 Tag and Release

Tag and release if not undertaken with care or without knowledge can contribute to White Sharks dying through the stress of being captured. Tag and release programs can provide information on movement patterns, site fidelity, growth, population estimates and mortality estimates. Tag and release programs must be assessed against the risk to the individual sharks and the benefit of the knowledge it is proposed to gain.

A full description of this threat can be found at Appendix C.

PART 1

1.1 INTRODUCTION

This Recovery Plan provides summary information on the White Shark, including biology, habitat, distribution and historical and current threats to its recovery.

The Plan has been developed in accordance with the Guidelines for the Compilation of Recovery Plans under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). It therefore sets out the recovery objectives, actions required to achieve those objectives, performance indicators, as well as identifying those responsible for implementing the actions and the timeframes involved. The Plan also identifies an aggregated costing for the recovery of the White Shark.

Additional information is provided such as guidelines for decision-makers and tools to assist the implementation of the Plan.

A comprehensive review of the biological information and current behavioural and ecological knowledge of the White Shark is provided in an appendix attached to this Plan.

1.2 CONTEXTUAL INFORMATION

1.2.1 The Region Covered

This Plan covers all Australian waters in which the White Shark is found.

The White Shark is widely distributed, and located throughout temperate and sub-tropical regions in the northern and southern hemispheres. In Australia, its range extends primarily from Moreton Bay in southern Queensland, with at least one record as far north as Mackay, (Paterson, 1990:154) around the southern coastline and to North West Cape in Western Australia (Bruce 1995).

1.2.2 Conservation Status, Historical and current size of Population

The White Shark, Carcharodon carcharias, is also known in Australia as the Great White Shark or White Pointer and is fully protected in Commonwealth waters under the EPBC Act where it is listed as a vulnerable species. The listing of the White Shark as vulnerable was based on a number of factors, including evidence of a declining population, its life history characteristics (long lived and low levels of reproduction), limited local distribution and abundance and at the time of listing, and still being under pressure from the Australian commercial fishing industry.

The White Shark is also fully protected in the coastal waters of Tasmania, South Australia, Victoria and Western Australia; and protected in the coastal waters of New South Wales and Queensland with exemptions made for beach meshing.

Internationally White Sharks are listed as ‘vulnerable’ on the IUCN Red List of threatened species (IUCN 2000) as well as protected in South Africa (1991), Namibia, the Maldives, Florida and California (US) and Malta.

There is little historical information on population estimates for the White Shark. The current population status of White Sharks in Australia is difficult to assess due to:

• poorly known stock structure and movement patterns;
• paucity of information on captures across all fishing sectors;
• ambiguities in available data;
• shortage of verified data; and
• lack of suitable indices of abundance or population monitoring programs.

Available data sets suggest a decline in abundance and size of White Sharks in some areas (Reid and Krogh 1992). These data include beach meshing records for New South Wales and Queensland, game fishing records from New South Wales and South Australia, and anecdotal sighting frequencies by tourism operators and divers in South Australia which all report declining catches and sightings (Bruce 1995). This interpretation is complicated by a marked interannual variability that may not be related to population size (Bruce 1995, Fox & Taylor pers comm. in Strong et al. 1992) as well as other factors such as changes in shark meshing regimes or decreased fishing effort (Peperell 1992). There are also competing claims that the number of White Sharks has increased in certain areas (for examplejuvenile White Sharks in some areas of Victorian coastal waters). Despite the inadequacies in the available data, there appears to be an overall, long-term decline in abundance of White Sharks in Australian waters

There are similarly few data sets from which an assessment for worldwide populations of White Sharks can be made. Game fishing data from the east-coast of North America indicate declines in the proportion of White Sharks taken relative to other shark species caught, similar to that reported off eastern Australia by Pepperell (1992). Casey and Pratt (1985) reported a drop in the ratio of White Sharks to all other sharks captured from 1:67 in 1965 to 1:210 in 1983 for the mid-Atlantic Bight.

Cliff et al. (1996a) reported marked interannual variability in the capture rates of White Sharks in the South African beach meshing program, with a cyclical period of 4-6 years. They also reported a significant decline in White Shark captures between 1973 and 1993.

1.2.4 Relevance to Indigenous Australians

There are no known significant interactions between Aborigines and the White Shark.

1.2.5 Relationship between the Plan and other Planning Processes

Comparable regulations or actions that reflect actions within this Plan have been introduced in South Australia, Victoria, Tasmania, New South Wales and Western Australia. The following table provides a summary explanation of the legislation underpinning the protection of the White Shark in relevant Australian jurisdictions.

1.2.6 Major benefits to other native species or communities

Section 270 of the EPBC Act requires that this Plan specifies any major benefits to species or ecological communities other than White Sharks that may be derived from actions taken in accordance with this Plan. Conservation measures to benefit White Sharks and their habitat may benefit inshore marine communities. In addition, by managing fishery bycatch and researching alternatives to shark meshing, these threats to other species, such as whales, dolphins, marine turtles, pelagic rays, some fish species and other sharks may be reduced,. Some of these species are also threatened or are uncommon. Marine communities may also benefit from any marine protected areas that may be established to protect White Sharks and conversely White Sharks may benefit from marine protected areas established within their range.

1.3 HABITAT CRITICAL TO THE SURVIVAL OF THE SPECIES

The EPBC Act specifies that recovery plans should identify the habitats that are critical to the survival of the species or community concerned and the actions needed to protect those habitats (S270 (2)(d).

To date there is little solid information or research findings upon which to identify habitat critical to the survival of the White Shark. An important early step towards the identification of habitat critical for the survival of the White Shark would be the identification of the characteristics of habitat critical to the survival of White Shark. Also as White Sharks appear to move through developmental habitats as they grow, the identification of critical habitat for White Sharks may be difficult given the unknown nature of their developmental needs at various life stages.

A full description of White Shark habitat can be found at Appendix B.

1.4 OVERVIEW OF THREATS AND ISSUES

There are a number of sources of mortality (other than natural mortality) of White Sharks in Australian waters. The most predominant of these are dealt with below.

1.4.1 Commercial Fishing

Despite not being commercially targeted, White Sharks are caught as bycatch on long-lines and in nets of professional fishers and in fin fish farm cages such as tuna farms. This is currently suspected to be the largest cause of mortality. The actual rate of capture of White Sharks by commercial fishers is difficult to assess and has not yet been quantified. This is because captures are not usually recorded, and in many cases, captured sharks are either not landed intact or not landed at all. Estimates of annual capture, based on anecdotal reports, range from less than 10 to 100 per annum in South Australia and 100 to 440 per annum for all fisheries (recreational and commercial combined) in Australian waters.

Further investigations are needed to quantify the capture of White Sharks from commercial fishing in each of the fisheries and establish the impact the commercial fishing industry has on the Australian population of White Sharks. It is necessary for commercial fisheries managers to assist industry to improve reporting of the take or interaction with White Sharks.

A full description of this threat can be found at Appendix C

1.4.2 Recreational Fishing

Prior to the implementation of protective legislation, game fishing for White Sharks was carried out mainly in South Australia, Queensland and New South Wales, but also in Victoria and Western Australia. Game fishing in South Australia for White Sharks was at its height in the 1950s. Between 1980 and 1990 White Sharks were also tagged and released although the survival rate of these sharks is not known. Further research in New South Wales using game fishing data for New South Wales calculated that the ratio of White Sharks to all shark species caught had changed from 1:22 in the 1960s to 1:38 in the 1970s and 1:651 in the 1980s. In the 1990s, capture of White Shark by game fishers off the coast of New South Wales was 13:2103 or 1:162 (Chan 2001). Prior targeting and removal of the largest and oldest of the population by game fishers would have had the effect of removing the most reproductively productive members of the population.

Game fishing groups have expressed a keen interest in accessing White Sharks for tag-release since the species was protected. Other groups have raised concerns that capture induced mortality or sublethal stress from tag-release activities may be unacceptably high. Issues of cryptic mortality, sublethal effect and scientific benefits also need to be addressed.

Other recreational fishers still occasionally capture White Sharks (for example in gill nets in Tasmanian waters and while fishing for other sharks in Western Australia, Victoria and New South Wales, and fishing for snapper in South Australia and Victoria). In some cases small White Sharks are mistakenly identified as other species (for example mako sharks).

A full description of this threat can be found at Appendix C.

1.4.3 Shark Control Activities

Shark control activities in Australia include beach meshing and drumlines, which most often kill the captured shark. Some non-lethal methods that are being trialed include using electrical fields to repel sharks but these practical trials have encountered many logistical problems. White Sharks are a target species in control activities but other non-target species are impacted by shark meshing such as turtles, dugongs and dolphins.

Queensland and New South Wales are the only two States to employ protective beach meshing. There are currently a total of 49 meshed beaches set offshore between Newcastle and Wollongong in New South Wales (approximately 200 km of coastline). In Queensland, a mixture of baited drumlines and nets are used. Drumlines consist of a marker buoy and float supporting a trace and baited hooks anchored to the bottom, and are intended to target dangerous species of sharks and reduce the bycatch of non-target species.

Shark meshing effort has increased over time. If the catch per unit effort (CPUE) equates to some measure of abundance then there has been a significant decline in White Shark abundance in both programs. The average size of White Sharks caught in New South Wales meshing operations has also declined over the period, though this is apparently not evidenced in the Queensland data. The degree to which beach meshing is impacting on White Shark populations is unknown although the decline in captures suggests it is significant.

A full description of this threat can be found at Appendix C.

1.4.4 Trade

The killing of White Sharks for trade targets two main areas – trade in trophy products such as jaws, and teeth and the trade in fins for food items such as ‘shark fin soup’. Increasing demand for White Shark products particularly fins, jaws, and teeth, has increased their value. Recent reports have been made identifying values of up to $50 000 paid for jaws from South Africa and $600 for individual teeth, despite their current protection there. Illegal trade in White Shark products may be a threat to the Australian population of White Sharks.

There are several commercial fisheries in Australia that frequently take shark fins as by product. Dried shark fin can attract a high price on Asian markets. The high market value for shark fins is leading to a high level of targeting of sharks that may be unsustainable. There is a growing acceptance that shark finning is both wasteful, when fins are removed and the carcass is discarded. This method is also a possible inducement to fishers to actively target sharks.

A full description of this threat can be found at Appendix C.

1.4.5 Tourism

Tourism does not pose a direct threat to White Sharks but through indirect means may limit the recovery of the population by altering the behaviour of the animal.

Both shark cage diving and shark boat tours are dependent on attracting sharks to an area by berleying (also known as ‘chumming’). Berleying involves releasing a mixture of fish oil and/or animal products into the water at regular time intervals to develop a slick to attract sharks in the vicinity. The use of berley may encourage White Sharks to appear or stay longer in a location that they would not normally visit, and there is the possibility that sharks will become habituated and begin to associate humans and boats with food. In addition the effect of berleying in areas adjacent to seal/sea lion colonies may result in higher mortality of seals/sea lions as a consequence of the increase presence of White Sharks. Tourism activities also raise the issue of disturbance to White Sharks and their prey. The effect of watercraft and human activities on sharks and marine mammals in the vicinity needs to be established.

However, it should be noted that some tourism activities in particular cage diving are contributing to data collection for further research

A full description of this threat can be found at Appendix C.

1.4.6 Tag and Release

Tag and release if not undertaken with care or without knowledge can contribute to White Sharks dying through the stress of being captured. Tag and release programs can provide information on movement patterns, site fidelity, growth, population estimates and mortality estimates. Tag and release programs must be assessed against the risk to the individual sharks and the benefit of the knowledge it is proposed to gain.
