from the computed net water flows,
2. better understand larval prawn dispersal mechanisms from the off-shore spawning grounds to the near-shore & estuarine nursery grounds

Summary

The prawn fishing industry in the Gulf of Carpentaria is worth $100 million/year and a large proportion of this is from catches of banana prawns. In one stage of their complex life history, banana prawn larvae are carried by ocean currents from their spawning grounds to the estuarine nursery areas.

The aim of this project was to define the currents that carry the larvae so that the life history can be more fully understood and various biological hypothesis concerning the banana prawn and in particular the behaviour of larvae can be fully tested. To achieve these goals a mixture of field work and theoretical modelling and cooperation between physical oceanographers and fisheries biologists was required.

Tactical Research Fund: Development and deployment of sterile ‘Judas fish’ to assist carp eradication in Lake Sorell, Tasmania - surgical and chemical sterilisation

In a world first, the project successfully developed reliable procedures for surgical sterilization of male carp and demonstrated that these when deployed as sterile ‘Judas’ fish are as competent as male ‘Judas’ carp in betraying the locations of feral populations thus...

Seafood CRC: A Final Seafood Omnibus: Evaluating changes in consumers attitudes and behaviours

The purpose of this project was twofold – firstly, to identify changes in consumers’ attitudes and behaviours over the past 5 years, and secondly, to further explore key issues impacting continued consumer trends. This study is the third Omnibus Consumer Research project carried out by...

The influence of fish movement on regional fishery production and stock structure for South Australia's Snapper (Chrysophrys auratus) fishery

From 2007 onwards, South Australia’s snapper (Chrysophrys auratus) fishery underwent significant and unprecedented changes that impacted on the management of the fishery. This ultimately reflected our poor understanding of the movement behaviour of snapper and its consequences for...

Rock Lobster Post Harvest Subprogram: the effect of on-board cold water stunning on the survival and growth of caught and returned western rock lobsters (Panulirus cygnus)

The relative recapture rates of returned stunned and unstunned lobsters have been quantified. Apparently conflicting results were obtained from two different areas of the fishery, but the results were deemed inconclusive due to low numbers of recaptures from water surrounding the Southern Group of...

Fish movement and migration - an ASFB workshop

Need

Most fish and other exploited aquatic species exhibit movement and / or migrations during some part of their life cycle. In recent years the importance of these migrations to fish and fisheries management has been increasingly realised. Changed fish behaviour due to varying environmental conditions has significant impacts on species availability/catchability and hence the interpretation of abundance indices. In freshwater, improved fish passage is seen as one of the major areas for river rehabilitation to be conducted over the next decade. Spatial models which take into account, explicitly or implicitly, fish movements are now widely used. Recent technological developments allow for greatly improved analysis of the patterns of fish movement and migration. This Australian Society for Fish Biology workshop will be the first time that migration and movement has been considered in a national forum.

The workshop will bring together scientists, managers and other stakeholders with general or specific interests in movement and migration. The workshop will cover theoretical aspects; techniques for measuring movement and migration, particularly new approaches and technologies (such as radio-telemetry, smart tags and otolith micro-chemistry); environmental determinants, barrier and human interference; analysis and input into spatial models; and management implications.

Objectives

1. To undertake a national workshop on fish movement and migration
2. To produce a 'benchmark' publication on the current knowledge of fish movement and migration

Summary

Through the generous support of FRDC and State, Territory and Commonwealth fishery agencies, the Australian Society for Fish Biology (ASFB) has hosted a national workshop series since the early 1980's with eminent local and overseas scientists presenting keynote addresses on major themes.  Increasingly, overseas scientists and managers have begun to attend these workshops as their reputation has spread.  The primary purpose of these workshops is to promote the opportunity for the national fisheries research expertise to focus on a technical area or subject of current national or regional significance.

Summary

This Workshop entitled Fish Movement and Migration continues the series, commenced in 1985 by the Australian Society for Fish Biology. The major objective of the workshops has been to focus national expertise on an issue that has regional or national significance. The proceedings are now widely regarded as the benchmark of current knowledge on the subject area.

Development of Fish Health Indicators for the Gladstone Harbour Report Card

As the link between land and sea environments, estuaries are complex ecosystems vulnerable to human impacts, which directly and indirectly affect plants and animals, including fish. Fish are key biological indicators of environmental contamination, as they are water breathers, common in aquatic...
