Lipofuscin is a metabolic by-product that accumulates in tissue of the nervous system, particularly the brain, and its occurrence has been shown to be widespread in crustaceans. Because it accumulates in the nervous tissue over time, the concentration of lipofuscin can be related to...
Australia has an abundant supply of terrestrial animal and vegetable protein feeds which has the potential to at least partly if not fully replace the fishmeal presently used in compounded aquaculture diets. A major difference between marine and terrestrial protein sources is the marked difference...
The history of BPLV in Australia is one in which mass mortalities have occurred repeatedly among cultured larvae almost completely without warning. There is no published data on where the virus comes from (i.e. its source or origin), or, in the case of stock being transferred interstate, the...
Lipids and in particular polyunsaturated fatty acids (PUFA) are important for a number of physiological functions in animals. PUFA are also major components of cellular membranes. Many marine animals cannot synthesise "essential" PUFA de novo and therefore serious deficiency signs such...
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;

Four different techniques for determining the stock structure of a marine fish species were compared, using as a subject the jackass morwong. The four techniques examined were allozyme analysis, mitochondrial DNA analysis and two techniques based on measuring the composition of otoliths ('ear...
The Western Rock Lobster (Panulirus cygnus George) is the most valuable single species fishery in Australia with an annual value in excess of $250 000 000. Consequently, there has been a substantial research effort geared towards gaining a better understanding of the basic biology of this species...
Ciguatera poisoning is a form of seafood poisoning that occurs in humans after the ingestion of particular specimens of a variety of tropical marine fish species. Ciguatera poisoning is caused by the ingestion of small quantities of a very powerful toxin, ciguatoxin (CTX), that occurs in the tissues...
Maugean Skate (Zearaja maugeana) are only known from two isolated estuarine systems located on the west coast of Tasmania, representing one of most restricted distributions of any elasmobranch. There is, however, uncertainty about the continued persistence of the species in one of these estuaries...
