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...

ESD Reporting and Assessment Subprogram: strategic planning, project management and adoption

The second stage of the operation of the ESD Subprogram was successful, but compared to the focus during the first subprogram period, mostly in a consolidation manner rather than from the generation of significant new tools. This was necessary because it takes time to adopt and integrate...

Identifying nursery areas used by inner bay and oceanic snapper stocks in the Shark Bay region, in relation to the effect of prawn trawling on inner bay snapper stocks

This study examined two aspects of the chemical composition of snapper otoliths from Shark Bay Western Australia as an aid to determining the spatial relationship among juveniles and to better understand the spatial relationships between juveniles and adults. Otoliths were collected from...

Comparing conventional ‘social-based’, and alternative output-based, management models for recreational finfish fisheries using Shark Bay pink snapper as a case study

This study has provided for the first time in Australia, an empirical comparison of different management models with a recreational marine finfish fishery. A TAC-based system was introduced for pink snapper in the inner gulfs of Shark Bay for the first time in 2003-2005, to explicitly manage...

Need

Incidental mortality in commercial fishing activities is acknowledged as an issue for many protected and endangered species throughout the world. Whilst Australia is considered a world leader in managing
these interactions, further improvements and development of additional knowledge is still required to
meet the expectations of the community. Within WA, to address the variety of interactions with protected
and listed marine species across all our commercial fisheries in a cost effective manner, an holistic and
integrated approach needs to be taken. Several protected species issues have already been identified through existing management processes, including entanglement of whales in fishing ropes and interactions between seals and demersal gillnets. These two issues involve protected species on the Commonwealth threatened list (i.e the Australian sea lion, Humpback and Southern Right Whale) which generates attention from both an ecological and political respect. A greater understanding of the factors involved in these interactions will be needed to design mitigation programs. Assessments at both the individual fishery and bioregional level will be required to input into the ecosystem-based fisheries management (EBFM) frameworks that are being developed for each WA bioregion. There is also the ongoing requirement for all fisheries to satisfy the protected species criteria under the EPBC Act which for some is vital to maintain their export certification. Moreover, there is the potential for significant pressure from advocacy groups to press for regulation of fishing effort or methods unless well-formulated management systems to address these pressing issues are developed.

Objectives

1. Development of risk-based management system using evidence-based science to assess the impact of incidental capture of protected and threatened speciesin the demersal gillnet fishery
2. Analysis and interpretation of the interaction between demersal gillnetting and pinnipeds based on fishing effort and pinniped foraging behaviour
3. Analysis of the factors influencing the rate of entanglement or large cetaceans in ropes of the Western Australia fishing industry and development of future interaction rate scenarios
