Development of a DNA database for compliance and management of Western Australian sharks

The capability to identify individual shark species from processed body parts is necessary for the WA Department of Fisheries to ensure the compliance of all WA fisheries with both existing protected species regulations and proposed new management measures for commercially important shark species....

Evaluating the potential use of change-in-ratio and index removal techniques for determining harvest rates and efficiency increases in the Western Rock Lobster Fishery

This project developed and explored methodology intended to enable the production of more reliable estimates of fishing efficiency increases and harvest rate, such that these estimates might be available for use by fisheries scientists, thereby improving the quality of the management decisions...

Aquatic Animal Health Subprogram: development of a national translocation policy using abalone and prawns as templates for other aquatic species

The use of scientifically based hazard identification, risk analysis and risk management is fundamental to managing unwanted effects. Hazards, such as quarantine incursions, will continue to occur despite the use of risk assessment methodologies but the frequency and severity of their...

Whale entanglements are a key performance indicator (KPI) for the WRL fishery in Commonwealth
assessments. Entanglements in 2012 (13 in WRL gear) exceeded this KPI. The KPI breach resulted in
the Commonwealth removing the WRL fishery from the List of Exempt Native Species which is a five
year export approval without conditions and issuing a two year Wildlife Trade Order (WTO) with
conditions and recommendations relating to whale entanglement. This included a condition: "by 31
March 2014, complete a robust evaluation of longer term operational management measures to
reduce the risk of whale entanglements, which could include the removal of some restrictions on
western rock lobsters, spatial and seasonal closures and potential gear modifications". If this condition
isn't met, the WTO may be revoked and therefore the
fishery will not be able to export. The WRL is almost exclusively an export fishery with an estimated
annual GVP of $200 million.
The reason for increased entanglements is a combination of whale population growth (10% p/a) and
an increase in winter fishing resulting from a relaxation of input controls after a move to quota. A
closed season, removing winter fishing would somewhat elevate this issue, although at an economic
cost to the industry as it would no longer be able to attain the high beach prices paid in winter. This
would result in a conservative loss of about $50 million p/a in GVP. Therefore to meet the SEWPaC
conditions, and still allow winter fishing, entanglement mitigation measures are needed.

Objectives

1. Examine the effectiveness of potential gear modifications to the float rigs of fishing pots/traps to reduce their likelihood of entangling whales.
2. Start to collect additional information required to determine the spatial and temporal extent of migrating whales and how this overlaps with commercial fishing gear.

Growth of pearl oysters in the southern and northern areas of the pearl oyster fishery and examination of environmental influences on recruitment to the pearl oyster stock

The pearling industry is Australia’s most valuable aquaculture industry, generating approximately $187 million in 1997 (source: ABARE 1997). The oysters used to culture pearls are derived almost entirely from wild stock shell, rather than hatchery produced stock as occurs in other major...

National Seafood Emergency Plan - Western Australia Trial Workshop

A National Seafood Emergency Plan was produced in 2001 and the individual States (apart from South Australia and Queensland) have not tested their capability to handle an emergency that could jeopardise the future of the seafood industry. There is a commitment from Industry leaders throughout...

Mitigation measures to reduce entanglements of migrating whales with commercial fishing gear

This project provided a robust assessment that gear modifications introduced into the WCRLMF and octopus fisheries have reduced the number of reported entanglements. The management arrangements around the implementation of these modifications are appropriate in light on the new spatial and temporal...

Regrowth of pilchard (Sardinops sagax) stocks off southern WA following the mass mortality event of 1998/1999

This project produced time series of estimates of spawning biomass for pilchards in four purse seine management zones in Western Australia, three on the south coast and one on the west coast. The pilchard stocks in Western Australia have recovered strongly since the 1998/99 mass mortality. This...
