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...

Seafood CRC: recovering a collapsed abalone stock through translocation

A Roe’s Abalone (Haliotis roei) fishery in Western Australia (Area 8) suffered catastrophic mortality (99.9%) due to an anomalous environmental event in the summer of 2011. During this extreme marine heatwave there was a sustained period of elevated sea surface temperatures that...

Compliance program evaluation and optimisation in commercial and recreational Western Australian fisheries

This project provides a database that can be used to estimate trends in compliance rates for different regulations in different fisheries. This enables fisheries compliance officers and managers to make informed decisions on the priorities for applying limited resources to ensure that the fisheries...

Improved performance of marron using genetic and pond management strategies

Marron (Cherax tenuimanus) are the highest valued freshwater crayfish farmed in Australia. This project addressed the need to increase the profitability of commercial marron farms by improving growth rates and pond management strategies. The project evaluated progeny produced from wild populations...

Seafood CRC: decision-support tools for economic optimisation of western rocklobster

The Western Rocklobster fishery was one of the first to be made limited entry with the number of licences restricted since 1963. Historically, the main focus of the assessment and management of the fishery has been on the status of the breeding stock to ensure biological sustainability. In the...

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.

RAC WA: Demographic Performance of Brownlip Abalone: Exploration of Wild and Cultured Harvest Potential

The report provides a comprehensive evaluation of Brownlip Abalone biology and fisheries assessment to date. For wild populations, it has provided the most reliable estimates of natural and fishing mortality, size composition and the first to model growth throughout all stages of life. The project...
