Quantification of changes in recreational catch and effort on inner Shark Bay snapper species following implementation of responsive management measures

A 12-month creel survey of recreational boat-based fishing in Shark Bay, Western Australia was conducted between May 2001 and April 2002 to estimate the catch of pink snapper. During the survey 431 boat crews were interviewed at public boat ramps of which 414 had been fishing. The information...

Assessing and managing interactions of protected and listed marine species with commercial fisheries in Western Australia

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

Management and monitoring of fish spawning aggregations within the West Coast Bio-region of Western Australia

Many strategies have evolved among fishes to maximise spawning success. One of the most striking of these is aggregation spawning, in which individuals group together, often at predictable times and locations in order to reproduce (cf. a school, which refers to a group of non-spawning fish)....

Modelling to explore management strategies to optimise the value of the rock lobster fishery of Western Australia

The fishery for the western rock lobster (Panulirus cygnus) is Western Australia’s most important single species fishery, and yields an average annual catch of 10,500 to 11,000 tonnes valued at between $200 and $300 million at the point of landing. With a high level of exploitation and a...

ASFB workshop: towards sustainability for data limited multi-sector fisheries

Project Status:
Completed

Need

The current ESD case studies project has identified multi-sector fisheries, often with limited data, as posing one of the most difficult areas for assessment of stock status. These fisheries are typically fished by a small number of commercial operators taking small catches of a diverse range of species. Comprehensive commercial databases are generally lacking, and recreational catches are poorly known. Such stocks are often significantly impacted by environmental variation both man made and natural.

There is an urgent need for researchers and managers responsible for future fisheries ESD reporting and assessment to examine techniques for data gathering (both catch/effort and biological) and assessment for these types of fisheries. The historical approach of dealing with the data and assessments of fisheries from a single sector perspective is no longer compatible with ESD requirements.

This ASFB workshop will bring scientists, managers, and other stakeholders together to investigate innovative ways of providing reliable assessments of the stocks and sustainable harvest levels for our coastal, estuarine, and inland fish resources.

Objectives

1. To explore alternative data sources for multi sector fisheries
2. To report on innovative methods for ESD assessment of multi sector fisheries.
3. To bring together researchers, managers and key stakeholders to focus on assessment and resource sharing for these fisheries.
4. Publication of the papers presented at the workshop as well as the subsequent discussion and comments.

Summary

FRDC and State agencies have generously supported an annual national workshop hosted by Australian Society for Fish Biology (ASFB) since the 1980’s. At the workshop, Australian and overseas scientists have presented keynote addresses on the theme of the workshop, followed by panel debates. The papers presented, and subsequent discussion are published in a book of proceedings.  The topic for the 2001 workshop, “Towards sustainability of data-limited multi-sector fisheries” was topical in light of the requirement for ESD reporting on Australian fisheries for EA, many of which are data poor. 
 
Two international scientists with a special interest in this area were invited to be keynote speakers: Dr Ana Palma, from Peitre Madro, in Argrentina and Dr Jim Ianelli from Seattle in USA.

Despite the collapse of Ansett, and travel bans by US government employees, 69 delegates attended. All papers were presented, albeit some not by the author, with the written papers and discussion published in July 2003. First drafts were reviewed by Stephen Newman, Daniel Gaughan, Gary Jackson, Micheal Mackie, Brett Maloney, and Jill St John from Department of Fisheries WA, final editing by Patricia Kailola, and print set up by Sandy Clarke.
