In this study, all seven projects in the Fishmeal Replacement Sub-Program were evaluated using the techniques of benefit/cost analysis. Projects under this Sub-Program covered the period 1993 to 1996/97. There were two types of project within the Sub-Program. Five of the projects were species-based,...

The Quantitative Training Unit for Fisheries is a project funded by the Fisheries Research and Development Corporation in the Institute of Marine Ecology at the University of Sydney. The Unit was set up in February 1995, initially for a period of three years. During that time, up to 3...
The First International Symposium on Abalone Biology, Fisheries and Culture was held in La Paz, Mexico in November 1989. In the closing session of that symposium it was decided to hold the second abalone symposium in Australia in 1993 or 1994. Subsequently, Hobart was chosen as the site and 7-11...

The relationship between spawning stock size and the size of the subsequent recruitment is fundamental to fisheries science. Without a working knowledge of the relationship it is not possible to know how heavily a spawning stock can be fished before recruitment levels begin to decline. Although...

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...

The issue of how best to survey abalone populations to obtain estimates of abundance has been the subject of debate among fisheries biologists for many years. In an attempt to resolve this issue we compared and evaluated abalone abundance estimated by the following methods: Transect survey,...
This report covers a five year study into the effects of trawling on seabed communities in the inter-shoal and inter-reef areas in the Far Northern Section of the Great Barrier Reef. The study arose from a GBRMPA convened scientific Workshop in 1989 to address the effects of fishing in the Great...

The objective of this project was to develop novel biological tags for penaeid prawns. The impetus for this research was the growing interest in Australia in the potential for stock-enhancement of penaeid fisheries with hatchery reared juveniles. In any stock- enhancement program some...
