Summary

Management of a marine renewable resource involves selecting a trade-off between conflicting objectives related to conservation and utilization. This problem is complicated by uncertainty about the current status and productivity of the resource being managed, and hence about the implications of alternative management measures. A general quantitative framework for evaluating these trade-offs in the face of uncertainty is developed. This framework allows for uncertainty about the current state of the resource and the observational error associated with future data. It can assess the performances of a variety of harvest strategies based on setting total allowable catches (TACs). These include constant catch, fixed escapement and constant fishing effort strategies. It is possible to constrain the changes in TAC from one year to the next. This framework is illustrated using the eastern stock of gemfish.

It is necessary to quantify the status of the resource to apply this framework. In this project, the historical trends in, current status of, and productivity of the eastern gemfish population is evaluated using two age-structured assessment approaches tailored to the specifics of the gemfish resource. These methods take account of the two-fishery nature of the resource, explicitly consider sex-­structure, and use the catches, the catch rates in the winter fishery, the length frequency data and the age-length keys. This resource is estimated to have declined markedly during the 1980s as a consequence of unsustainable catches and a long series of weak year-classes. However, the assessments cannot distinguish among alternatives for the relationship between spawning stock size and future recruitment. The two assessments arrive at different conclusions regarding the size of the resource relative to AFMAs harvesting target of 40% of virgin level.

Summary

In an earlier ABARE study of the efficiency of seafood marketing (Smith and Reid 1993) it was suggested that alternative marketing arrangements have the potential to improve the efficiency of seafood marketing. Among the options canvassed was the possibility of developing electronic marketing of seafood. Electronic marketing systems may be well suited to the fishing industry's operations, particularly to domestic marketing, where the majority of product is sold in fresh chilled form, requiring the rapid movement of product, and where there are wide variations in both fishing and marketing operations.

Electronic marketing encompasses any form of marketing activity which is undertaken remotely through a computer network. Under an electronic marketing system, buyers and sellers are able to trade by offering or bidding for products through their own computers, networked to a central computer system, recording bids according to a specified sale structure. Such systems allow a large number of buyers and sellers to simultaneously participate in a sale. Electronic marketing systems have been developed and implemented for some agricultural products, such as livestock, but are not widely used at present.

The objective in this project is to identify potential applications of electronic marketing in the fishing industry, some of the likely benefits that may result, and the conditions that would need to be met for these benefits to be realised. Identifying the full extent of the potential benefits and costs of electronic marketing was outside the ambit of this study. The benefits of electronic marketing will vary widely between different user groups, and a full assessment would require detailed information on the current operations of a wide array of potential users. Similarly, the costs will be influenced by the administrative arrangements adopted in establishing the computer network and the technologies used, both of which are subject to considerable uncertainty.

To review previous research on northern mackerel and to assess current and future research needs for these fisheries

Project number: 2002-096
Project Status:
Completed
Budget expenditure: $23,950.00
Principal Investigator: Timothy M. Ward
Organisation: SARDI Food Safety and Innovation
Project start/end date: 25 May 2002 - 30 Sep 2003

Objectives

1. Document past (at least 10 years) and current research projects funded by all agencies and identify the outcomes and consequent uptake of results by stakeholders (impacts).
2. Provide comment on the degree to which the R&D has met management needs and has been used to improve the management arrangements.
3. Undertake a benefit cost analysis of the previous R&D.
4. Evaluate fishery(s) strategic research plans with respect to whether domestic management needs, industry development, environmental assessment
and domestic fishery assessment requirements are adequately addressed.
5. Identify significant gaps in current and proposed future research plans and projects, including reference to needs arising from strategic assessment of the fishery under the EPBC Act and demands arising from increased recreational catch.
6. The species to be included are: Spanish mackerel, small mackerel
grey mackerel and spotted mackerel.
