Seafood CRC: optimising business structures and fisheries management systems for key fisheries

There is currently an estimated economic gap (lost profit) in the CRC participant fisheries of approximately 40% or $200 million per annum.. If the economic gap could be halved from 40% to 20% the profitability of CRC fisheries would be improved by approximately $100 million. This project aimed to...

Need

There are increasing national and international pressures to manage fisheries according to the principles of Ecologically Sustainable Development (ESD, e.g. Convention on Biological Diversity 1992; National Strategy for Ecologically Sustainable Development 1992; Australia's Ocean's Policy 1998).

Implementing ESD for Australia’s fisheries means that research and management will need to focus increasingly on ecosystem effects. Recent assessments have shown that few data are available on the ecological effects of most fisheries.

These concepts and approaches are in the developmental stages and need to be better defined, applied and communicated.

This project meets four of the strategies within the FRDCs Natural Resources Sustainability Program:
(1) Interactions between fish and their ecosystems;
(2) Effects of fishing activities on fish and their ecosystems;
(3) Health of fish and their ecosystems; and
(4) fisheries and ecosystems management.

Funding this project would ensure FRDC involvement in this critical national initiative in fisheries research and management and extend the valuable long-term relationship between FRDC and ASFB.

Objectives

1. To conduct the ASFB2004 workshop as the "National Symposium on the Ecosystem Research and Management of Fisheries".
2. To involve international and Australian experts on: pelagic fisheries and trophodynamics
temperate reef fisheries and benthic communities
and rivers and estuaries with limited and variable flows.
3. To publish the proceedings from the Symposium in a peer-reviewed, high-quality format, perhaps as a special edition of Marine and Freshwater Research (MFR).

Development of an integrated fisheries management model for King George whiting (Sillaginodes punctata) in South Australia

Project number: 1995-008
Project Status:
Completed
Budget expenditure: $461,163.00
Principal Investigator: Anthony J. Fowler
Organisation: SARDI Food Safety and Innovation
Project start/end date: 29 Dec 1995 - 30 Jun 2001
Contact:
FRDC

Objectives

1. To produce an age-structured, spatial-temporal fishery model for King George whiting in South Australia based on a comprehensive understanding of its biology, life-history and genetics as well as an analysis of the fishery. This model will be used as a stock assessment tool to assess management options.
2. To implement a biological research programme to facilitate objective 1/, including: a/. determination of site-specific age-structures based on ageing fish using otoliths, to be used for estimation of demographic parameters
b/. completion of the understanding of the life-history including reproductive, early and adult biological information
c/. assessment of genetic variation amongst populations over two spatial scales (amongst states and amongst regions within SA).
3. To review current commercial catch and effort information to: a/. identify the value of such data for estimating population abundance
b/. continue an on-going assessment of impacts of technological advances in fishing equipment on catch and effort in the commercial sector of the fishery
c/. compare commercial catch with that from recreational catch information currently being collected in SA using creel surveys (FRDC 92/81).

Summary

The King George Whiting Simulator (WhitSim) is a simulation version of the Whiting Estimator (WhitEst) encased inside a graphical user interface (GUI) that includes geographical information systems (GIS). WhitSim provides the ability to simulate various management strategies and parameter scenarios and interrogate results of the simulation via in-built statistical, curve fitting and indicator analysis modules.

Summary

King George whiting (Sillaginodes punctata) remains a prime target species of the marine scalefish fishery of South Australia. Levels of fishing mortality are high on inshore populations throughout the fishery which has caused concern about the level of egg production. This prompted the need for a comprehensive stock assessment for this fishery. However, complicating this task is the fact that the life-history incorporates an obligate migratory step where fish move from shallow, inshore areas where they are heavily targeted, to deeper, more exposed places where the spawning populations occur.

Tactical Research Fund: Shark Futures - Using molecular techniques to improve the ecologically sustainable fisheries management of shortfin makos (Isurus oxyrinchus) in the Australasian region

Need

Please consider this proposal under Theme 1. Demonstrating Sustainability: Evidence based and low-risk management for Shark-Associated Fisheries.

Information on the genetic population structure of shortfin makos was identified as a research priority at the recent FRDC-funded Australasian Mako Shark Workshop. A support letter was provided by the PI of the workshop, Barry Bruce of CSIRO, Hobart (find attached).

At the workshop it was highlighted that:
1) completion of the current population structure study was a high priority,
2) further sampling resolution was required for the Indian Ocean.

Declines in shortfin mako populations in the Northern Hemisphere led to the listing of this species as ‘Vulnerable’ by the International Union for Conservation of Nature (IUCN) and the Convention on Migratory Species (CMS). The CMS listing led to the nomination under the Australian Commonwealth Environmental Protection Biodiversity and Conservation Act (EPBC Act, 1999). The listing was debated by stakeholders and was later amended.

A representative from the Australian Fisheries Management Authority indicated that information on the abundance of shortfin makos was a priority for management of Commonwealth fisheries. This proposal addresses this priority for shortfin makos in the Australasian region.

There is limited evidence that shortfin makos make cross-equatorial migrations. Satellite tracking of juveniles by the PI showed restricted northward movements. This suggests that the Southern Hemisphere may comprise one or more independent stocks. This has important implications for management.

Outcomes will be used to inform decisions on whether to manage shortfin mako stocks at ocean basin and/or cross ocean-basin scales, or as discrete spatial units within smaller regions. This will greatly enhance our capability to make recommendations to State and Commonwealth government agencies chartered with managing pelagic fisheries, as well as during the development of fishery risk assessments and Threatened Species Recovery Plans in the future.

Objectives

1. To use new genetic data to assess the patterns of population structure of shortfin makos within the Australasian region
2. To compare the geographic scale of genetic connectivity with migration patterns determined from satellite tags deployed on juveniles
3. To incorporate our dataset within a larger global study and elucidate the degree of cross-equatorial dispersal of shortfin makos
4. To use the data to determine the genetic effective population size of identified spatially discrete stocks
5. To provide advice regarding the appropriate spatial scales for management of fisheries that interact with shortfin makos in the Australasian region.

Tactical Research Fund: a reporting framework for ecosystem based assessment of Australian prawn trawl fisheries

This Tactical Research Fund Project has been undertaken by SARDI Aquatic Sciences in response to the Spencer Gulf Prawn Fishery’s (SGPF) need for an ecosystem-based reporting framework to support ongoing Marine Stewardship Council (MSC) certification. We reviewed the relevant literature to...
