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...

Squid, octopus and cuttlefish (cephalopods) are known to be an important food source for many marine animals including whales, porpoise, seals, seabirds, tuna, sharks and swordfish. The hard beaks (chitinous mandibles) of these preys are frequently encountered in predator stomachs. Cephalopod beaks...
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 standard method for growing the early stages of juvenile Pacific oysters is to hold them in systems called upwellers in land-based nurseries. Seawater is pumped through to provide the oysters with food particles. Growth rates of oysters cultured using this method were highly variable at Pipe...
The fishing industry needs accurate ways to measure the age of animals to manage their populations better. The project shows that researchers studied the growth of receptors in crabs and lobsters to see if they could be used to determine age. They found that counting the number of receptors is only...
In November 1992, this project commenced with the development of methods for the evaluation of striped trumpeter (Latris lineata) larvae cultured by the Finfish Development Program (FDP). The first year was spent in the selection of digestive enzymes for investigation and the modification of methods...
