The bioassay section of this study provides, for the first time, estimations of lethal and growth reducing concentrations for the major production-limiting water quality variables for P. monodon. These critical concentrations were assessed using comparable experimental facilities and procedures....
The purpose of this project was to study the use of mid-water and surface structures (Fish Aggregating Devices - F.A.D.'s) in attracting commercial species of pelagic fish in economic quantities.
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 aim of this project was to farm, on a pilot commercial scale, two indigenous species of marine fish: snapper, Pagrus auratus; and mulloway, Argyrosomus hololepidotus.
The project involved:
development of hatchery techniques;
intensive rearing of larvae;
transport of live fish;
...
There is worldwide concern over the potential effects of by-catch and discarding of fish in commercial fisheries, particularly trawling. Although mortalities of discards are highly variable, it is likely that a large proportion of fish discarded at sea by trawlers do not survive. Consequently,...
