Measuring the feeding range of western rock lobster and the effective fishing area of a baited pot

Food is a primary factor affecting the growth and survival of juvenile western rock lobsters in nursery areas. Determining how far juveniles travel when searching for food is essential in determining the size of area foraged and how much food is potentially available to them. Knowledge of foraging...

Stock identity of northern fish species

The research program supported by this grant was directed at determining the number and distribution of subpopulations or genetic stocks which contribute to Australian fisheries for barramundi, northern sharks, and narrow-barred Spanish mackerel. Starch gel electrophoresis was used to reveal...

Northern pelagic fish stock research

In 1982, CSIRO applied to the Fishing Industry Research Trust Account for funding of a joint biological investigation of northern Australian pelagic fish stocks. At that time these stocks supported a Taiwanese surface gill-net fishery based on sharks, tunas and Spanish mackerel. During the 1970's...

Age determination and assessment of variation in length at age of large southern bluefin tuna by means of otolith and vertebral chemical composition

Patterns of ontogenetic variation in the composition of the otoliths of southern Bluefin tuna (SBT), Thunnus maccoyii, strongly suggested that the concentrations f some elements (and particularly strontium) varied episodically, and probably annually. This suggested that counting the numbers of peaks...
