Retrospective assessment of ITQs to inform research needs and to improve their future design and performance

The use of transferable fishing rights has increased internationally over recent decades with most industrialised countries now using some form of individual transferable catch quota (ITQ) or individual transferable effort (ITE) system for at least some of their fisheries. Australia also has...

Blue carbon and the Australian seafood industry: workshop

Several stakeholders within the Australian seafood industry have demonstrated strong leadership by developing carbon neutral business practices. In 2017, participants in the National Seafood Industry Leadership Program challenged the industry to become carbon neutral by 2030. In response, the...

Need

Australian fisheries are small by world standards, in terms of production, but have a large geographic, ecological, social and political footprint. Wild fisheries production averaged around 160,000 tonnes per annum between 2010-11 and 2012-13. The National Marine Science Plan notes that Australia needs to address our current and potential future gaps in food self-sufficiency and improve production as part of reducing our reliance on imports, as we currently import 72 per cent of our seafood. However, it has been reported in recent years that there is little scope for an overall increase in wild fisheries production. For example in Working Together: the National Fishing and Aquaculture RD&E Strategy 2010, it states “little opportunity exists to increase the volume from wild-catch fisheries”. Such statements have never been formally tested and could, if they are believed, constrain future investment by government and industry.
The aim of this project is to take the first national look at what sustainable national fisheries production could be. The project will consider catches of key commercial species at suitable target reference points. If, for a particular fishery or species, these are not identified then Bmsy will be the default. In addition, the potential for increased catches of selected by-product and by-catch species will also be considered. All jurisdictions will contribute to the project. The focus of this proposal is on the biological sustainability and limits to sustainable catches in the long term. Other factors such as whether there is a market for the potential production and whether the economic value will be optimal if production is maximized are clearly important, along with other market and economic issues, but will not be considered here.
This proposed project can be seen as a first stage. A second stage may be required if it is determined that there is potential for a large increase in production. A second stage project would look at species interactions (that could prevent all species being fished at their target reference points simultaneously), implications of an increased fishery footprint required to achieve the extra catch, and market issues.

Objectives

1. Develop a nationally agreed framework of methods to estimate sustainable yields
2. Review and identify species that may have potential for significant growth in catches
3. Application of methods to determine potential total sustainable yield from Australian fisheries
4. Identify next steps if a large potential increase in production is possible

Summary

This project was a first attempt at estimating the total potential maximum sustainable yield (MSY) from Australia’s commercial fisheries. The project considered only key commercial species and selected by-product species. Estimating equilibrium MSY where there was a formal stock assessment was relatively easy, as the assessment models provide this information.  Where existing MSY estimates were available, these were used.  In other cases, a multi-level assessment framework for estimating MSY was developed and related software addressed data-rich to data-poor assessment methods.

Improve catch rate standardizations to account for changes in targeting

In Australia many stock assessments are dependent upon catch-per-unit-effort (CPUE) to act as an index of relative abundance of fished stocks through time. But CPUE trends can be affected by many factors other than just stock size changes. Around Australia, and internationally, numerous and...

Atlantic Salmon Aquaculture Subprogram: molecular genetic tools for the Tasmanian Atlantic salmon industry – development and application

Archived DNA was successfully extracted from 30-year-old dried scales collected in 1971 and 1972 from wild Atlantic salmon from the River Philip, Canada. Genetic variation was assessed at 11 nuclear DNA microsatellite loci (three tetra- and eight di-nucleotide repeats) in two samples from the River...

Resolution of taxonomic problems and preparation of a user-friendly identification guide to whole fish and fillets for South East Fishery "quota species"

An upgraded identification guide to fish and fillets of the South East Fishery (SEF) quota species groups has been compiled from new information. This reference, South East Fishery.Quota Species: an Identification Guide (Daley et al., 1997) and hereafter referred to as SEF Species Guide, was...

Reducing the Number of Undefined Species in Future Status of Australian Fish Stocks Reports: Phase Two - training in the assessment of data-poor stocks

Seven data-poor assessment method training workshops were run in seven different jurisdictions (Tasmania, Victoria, South Australia, Western Australia, Northern Territory, Queensland, and New South Wales). Originally the workshops were to have been undertaken from March to the end of May 2018....

Testing abalone empirical harvest strategies, for setting TACs and associated LMLs, that include the use of novel spatially explicit performance measures

The management of abalone stocks is difficult for many reasons including their high value and the exceptional levels of spatial structuring found in their stocks. In Tasmania, for example, suggestions to change such things as a legal minimum length or introduce a formal harvest strategy to replace...
