Introduction to Torres Strait Fisheries

The Torres Strait Treaty between Australia and Papua New Guinea (PNG) was ratified in 1985. It requires that the two countries conserve and achieve optimal utilisation of the Torres Strait fisheries and maximise the opportunities for the traditional inhabitants of both countries to participate in the fisheries.

The treaty describes the boundaries between Australia and PNG and how the shared sea resources are to be managed. The treaty established the Torres Strait Protected Zone and the rights of Australia and PNG to share the commercial fisheries of the protected zone.

The enacting legislation for the treaty in the area under Australian jurisdiction is the Torres Strait Fisheries Act 1984, which establishes the Protected Zone Joint Authority (PZJA). Membership of the PZJA comprises the Australian Government and Queensland Government ministers responsible for fisheries and the chair of the Torres Strait Regional Authority.

The Torres Strait Fisheries Act 1984 provides for the PZJA to make plans or policies for the management of fisheries in the Torres Strait.

Two sectors operate within all Torres Strait commercial fisheries:


  • traditional inhabitant boat (TIB) licences are available to Traditional Inhabitant fishers only; and

  • transferable vessel holder (TVH) licences are available to other commercial fishers.

Description of the Torres Strait Bêche de mer Fishery

The Torres Strait Bêche-de-mer Fishery provides for the harvest of multiple species of sea cucumber, for the production of bêche-de-mer. The terms bêche-de-mer (French) and trepang (Indonesian) are interchangeable. However, "trepang" is usually considered to be the dried body wall, while "bêche-de-mer" is considered to be the cooked body wall of sea cucumber.

The fishery is managed on behalf of the PZJA under the Torres Strait Fisheries Act 1984 by the Australian Fisheries Management Authority (AFMA).

The area of the fishery (Figure 1, page 11) extends from the tip of Cape York to the northern border of Australian jurisdiction in the Torres Strait Protected Zone and includes islands and their territorial waters recognised within the Torres Strait Treaty as being Sovereign Islands of Australia.

Historically, sea cucumbers have been harvested in eastern Torres Strait. The western Torres Strait reefs have been documented as having a very low abundance of all sea cucumber species. Since 2005, the majority of sea cucumber harvest has occurred in the central eastern Torres Strait regions comprising of the Great North East Channel, Don Cay and Cumberland regions.

There has been little activity in the fishery in recent years owing to the prohibition on harvest of many of the high value species in the fishery including sandfish, black teatfish and surf redfish.

Target Species


At least 16 species of sea cucumber are known to have been taken commercially in the Torres Strait Bêche-de-mer Fishery including white teatfish, prickly redfish, deepwater redfish and blackfish. Due to observed declines in abundance, take of three species is prohibited in the fishery:

  • sandfish (Holothuria scabra) since 1998;

  • pacific black teatfish (Actinopyga mauritiana) since 2003; and

  • surf redfish (Holothuria whitmaei) since 2003.

Sea cucumbers are found on coral reefs and adjacent shoals, seagrass beds and sandy and silty benthos in shallow tropical seas. The habitat of sea cucumber species ranges from intertidal and inshore mudflats to inshore reefs and deepwater areas. Sea cucumber stocks generally are considered particularly vulnerable to over exploitation due to limited dispersal, patchy distribution, ease of collection, slow recovery from over fishing and the limited available information on biological and spatial distribution. Wilson et al 2010 conclude that the sessile nature of sea cucumbers and their relatively restricted mobility make them inherently vulnerable to localised depletion.

Further information on the biology of the target species can be found in the 2005 assessment of the fishery located on the department’s website at: http://www.environment.gov.au/coasts/fisheries/commonwealth/torres-strait-beche-de-mer/index.html



Byproduct, bycatch and protected species interactions1

Due to the selected harvest methods (hand-collection only, with the use of self contained underwater breathing apparatus (SCUBA) and hookah gear not permitted) and targeted harvesting, there is no byproduct or bycatch in the fishery, and interactions with protected species are likely to be minimal. No interactions have been reported from the fishery to date.

Fishery status

The stock status of Torres Strait Bêche-de-mer Fishery sea cucumber stocks is reported in the 2009 fishery status report (Woodhams and Rodgers 2010) as:

  • sandfish - overfished, subject to overfishing;

  • black teatfish - not overfished, not subject to overfishing;

  • prickly redfish - not overfished, not subject to overfishing;

  • white teatfish - not overfished, not subject to overfishing;

  • surf redfish - uncertain, but not subject to overfishing; and

  • all other sea cumber species combined - uncertain, but not subject to overfishing.

Take by other sectors

There is believed to be no history of traditional fishing for sea cucumbers for local consumption. Possession limits apply to traditional fishing. As sea cucumber is not part of the traditional Indigenous diet, recreational catch is assumed by AFMA to be minimal.

In 2009, the Papua New Guinea Sea Cucumber Fishery, immediately to the north of the Torres Strait Bêche-de-mer Fishery, was closed for a period of three years.

In 2011, two five-year developmental fishing permits were issued by fisheries Queensland to allow for limited annual harvest of a range of sea cucumber species in the Gulf of Carpentaria, to the south west of the Torres Strait Bêche-de-mer Fishery.

Illegal fishing by foreign nationals is recognised by AFMA as the most significant compliance risk in the fishery. It is thought that prior to the closure of the Papua New Guinea Sea Cucumber Fishery, considerable exploitation of sea cucumber in the area of the Warrior Reef complex by illegal foreign fishers occurred, focussing on species for which take was prohibited in the Torres Strait Bêche-de-mer Fishery. With the closure of the Papua New Guinea fishery and consequently a lack of buyers in Papua New Guinea, AFMA considers that the risk of illegal fishing has declined markedly since 2009.



Gear

Fishing by operators who hold transferable vessel holder (TVH) or traditional inhabitant boat (TIB) licenses is limited to hand collection from vessels less than seven metres in length. Hand held non mechanical devices may be used.

The use of self contained underwater breathing apparatus (SCUBA) and hookah gear is prohibited in the fishery. Collection is restricted to walking on reef tops or free diving to depths estimated to be predominantly less than 10 metres.



Season

Year round (January - December).

Commercial licences issued

There were 76 licences issued in 2008 and 49 licences issued in 2009.

Since 2008, there have been only three active fishers, all TIB fishers.



Commercial harvest

Little commercial catch has been reported in the fishery since 2005, which AFMA attributes to low market prices prevailing for the sea cucumber species for which commercial harvest was allowed during that period.

A small commercial catch was reported in 2007 and 2010 but for confidentiality reasons the amounts are not reported publicly.



Management arrangements

The Torres Strait Bêche de-mer Fishery is managed by AFMA under the Torres Strait Fisheries Act 1984 and Torres Strait Fisheries Regulations 1985, and legislated through Fisheries Management Notices issued under the Torres Strait Fisheries Act 1984 as well as conditions on fishing permits.

Input controls

  • entry limited to licensed TIB holders (except for one TVH licensed operator);

  • maximum vessel size of seven metres;

  • collection is by hand or non-mechanical hand held devices; and

  • the use of hookah and SCUBA gear is prohibited.

Output controls (2010-211)

  • minimum size limits on 10 species in the fishery;

  • zero total allowable catch for sandfish, black teatfish and surf redfish;

  • competitive annual total allowable catch for white teatfish (15 tonnes) and prickly redfish (20 tonnes); and

  • combined total allowable catch for remaining sea cucumber species of 80 tonnes.

Traditional Fishing Controls

  • bag limits of three per person or six per boat.

Export

All processed product is for export (primarily to Asia) in dried, frozen, pickled whole or other processed forms.

Ecosystem Impacts


AFMA's 2011 submission indicated that the potential impacts of the operation of the fishery on the ecosystem include:

  • potential over-exploitation of target species;

  • potential translocation of species via hull and anchor fouling; and

  • potential impacts of anchoring/mooring and other anthropogenic activities such as treading on reef top habitat.

Due to harvesting methods in the fishery being restricted to hand collection, impacts on the physical ecosystem are likely to be limited.

Sea cucumbers are believed to play a role in the nutrient recycling pathways of benthic environments. The setting of total allowable catches in the fishery minimises the potential for unsustainable removal of sea cucumber species.



Impacts on the World Heritage Values of the Great Barrier Reef World Heritage Area and the Great Barrier Reef Marine Park

The assessment also considered the possible impacts on the World Heritage values of the Great Barrier Reef World Heritage Area and the Great Barrier Reef Marine Park, which are in close proximity to the Torres Strait Bêche-de-mer Fishery. Under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act), a person may not take an action that has, will have or is likely to have a significant impact on the World Heritage values of a declared World Heritage property or the Great Barrier Reef Marine Park.

As the area of the fishery does not include the Great Barrier Reef World Heritage Area or the Great Barrier Reef Marine Park, and there are measures in place in the fishery to control the take of sea cucumbers, the department considers that an action taken by an individual fisher, acting in accordance with the management regime for the Torres Strait Bêche de-mer Fishery, would not be expected to have a significant impact on the Great Barrier Reef Marine Park or the World Heritage values of the Great Barrier Reef World Heritage Area.
