A sampling method was developed to quantify changes in the abundance of abalone on reefs in NSW from Port Stephens to the Victorian border. The method is based on the repeated sampling of the same, fixed areas and has been used each year since 1994 to provide indices of the relative abundance of...
Most Australian abalone fisheries are fully exploited and a comparison of the total catch of blacklip abalone, Haliotis ruber, in the three south-eastern states indicates a decline in population size from south to north. The catch distribution from New South Wales parallels that trend. This decline...
For this very new fishery, those aspects of the species' biology most relevant to its management and continued exploitation are its distributions, abundances and rates of growth. Unfortunately at the start of this project/ we knew none of this information for the NSW stock. As a first step I...
The snapper, Chrysophrys auratus, is an economically valuable common property resource that occurs in large numbers in New South Wales waters. Allegations of a resource decline in this major target species of both commercial and recreational fishermen have led to conflict over fishing access and...
This project was prompted by poor or variable availability of wild commercial scallop spat for fisheries enhancement and farming in southern Australia and by generally poor and variable success of commercial oyster hatcheries in earlier attempts to fill this shortfall.
Scallops from Jervis Bay,...
The objectives of this study were to determine whether catch rates of rock lobsters in the commercial fishery off New South Wales were declining, the size and species composition of catches from the commercial fishery and to ascertain the smallest length at which 50% of female eastern rock lobsters,...
