Determining biological characteristics of the champagne crab (Hypothalassia armata) for management purposes

During recent years, commercial trap fisheries have developed for the champagne and crystal crabs in deep waters off the lower west and south coasts of Western Australia. Thus, data on crucial aspects of the biology of these species were required to enable plans to be developed for conserving their...

Objectives

1. Determine whether the Australian spanish mackerel resource, comprising four main species of the genus Scomberomorous, is exploited recreationally and commercially in three distinct areas of tropical Australia, in each of which the stock of each species is an autonomous stock
2. To determine if the species composition of the resource is the same in the 3 areas
3. To determine if the three unit stocks of search of the 3 smaller species differ as to growth rate, reproductive potential or survival rate under average environmental conditions or in consequence in composition as to sex age and size
4. To determine if the resultsobtained from Deuel surveys will be sufficient basis for allocating fishery access as between commercial and recreational fishers
5. To determine if the Deuel special survey method can yield a reliable estimate of the amount of the fishing for the small mackerels by commercial and recreational fishers in remote regions of northern Australia.

Summary

The small mackerels comprising school mackerel (Scomberomorus queenslandicus), spotted mackerel (S. munroi) and grey mackerel (S. semifasciatus) are important and valued species to recreational and commercial fishers in northern Australia. Prior to this project very little was known about the basic biology of, or fisheries for, small mackerels. Each species was found to exhibit distinct life history patterns with differing stock structures. Though there is some overlap between fisheries, there was much spatial and temporal separation of the fisheries, with gill net specialisation for each species targeted by the commercial fishery. Recreational hook and line fisheries for school mackerel and spotted mackerel were important with most of the grey mackerel harvest taken by the commercial sector.

Seafood CRC: economic management guidance for Australian abalone fisheries

Current Australian abalone fisheries management primarily uses biological and catch data to set total allowable catch limits (TACs). Performance targets are usually based on trends in catch rate or catch and aim to maintain these indicators within historic bounds that have prevented recruitment...

Northern pelagic fish stock research

In 1982, CSIRO applied to the Fishing Industry Research Trust Account for funding of a joint biological investigation of northern Australian pelagic fish stocks. At that time these stocks supported a Taiwanese surface gill-net fishery based on sharks, tunas and Spanish mackerel. During the 1970's...

Need

Projects within the FHT require contribution from staff with resource economics skills because the theme is pursuing higher economic yield. The need for specialised input is far greater than in other areas of the CRC because improved economic outcomes in wild fisheries involve balancing complex trade-offs. For example, higher catch in wild fisheries usually results in complex, non-linear changes in cost of fishing as stocks become scarcer. These systems require specialised skills and substantial research effort to model and understand.

The common-pool nature of wild fisheries means that business decisions that are good for the individual are often bad for the collective. Consequently, wild fisheries tend to evolve towards low economic yield in the absence of management decision making based on economic analysis. Evidence of this is that Australia's best performing wild fishery is one where there is no common pool problem - the Exmouth gulf fishery is operated by a single company. Likewise individual aquaculture firms can adjust their production without impacting on the productivity of other producers. The point here is that the FHT will be reliant on quality resource economics support if it is to achieve its goals of growth in earnings and NPV.

Maximising net economic returns from a multispecies fishery

Achieving fishery MEY may result in a reduction in net economic returns in a broader sense if the loss to consumers exceeds the gain to the industry. Such a loss may occur if supplies to the local market are reduced and prices paid by consumers increase. This results in a transfer of benefits from...
