Distribution of benefits between commercial and recreational fishers from policies implemented to control fishing effort in commercial fisheries: An application to the Coffin Bay King George whiting fishery
Final report
Recreational boat fishers using the Coffin Bay boat ramp between January and June 1990 were interviewed to obtain information on their fishing activities. Recreational boat fishing is an important activity in Coffin Bay. The majority of fishers targeted King George whiting (Sillaqinodes punctata), which accounted for over half the total catch. The average catch rate of King George whiting per angler hour was 1.25 fish. Information was obtained on the value fishers place on recreational fishing. These data were included in a simple model of the fishery to evaluate the economic benefits of changing the current allocation of fish between commercial and recreational fishers. The analysis indicates that it may be desirable to reduce recreational fishing and increase commercial fishing in Coffin Bay. Further research is required to verify this finding.

Assessment of potential for commercial yabbie farmlng
Final report
The yabbie, Cherax destrucor has been identified as an Australian freshwater crayfish species having a very high potential for aquaculture. Research Into biological aspects of the yabbie (Carrol I 1981, Mills 1983) has demonstrated +ha+ commercial farming of yabbies Is technically feasible. However, there is little information available on the profitability of investing in, and developing, commercial yabbie farms. In 1986, a research project was initiated by the South Australian Department of Fisheries to assess the potential for commercial yabbie farming operations. The project was supported by a grant from the Fishing Industry Research Trust Fund Account. Some key results from the research are summarised In this article, prospective investors requiring further information can obtain a copy of the complete report (Sanford, Kuznecovs and Mills, 1987) from the Department.
Settlement and recruitment of greenlip abalone: their use in predicting stock abundance
Final report
The purpose of the grant was to develop a method of measuring density of settlement of the abalone Haliotis laeviqata in relation to spawning stock size and the subsequent catch in the fishery. It was hoped that settlement strength, if it was controlled by oceanographic conditions, would be a useful index of subsequent abalone abundance, and so would provide a method of predicting abalone catches.
