Evaluation of harvesting strategies for Australian fisheries at different levels of risk from economic collapse

Management of a marine renewable resource involves selecting a trade-off between conflicting objectives related to conservation and utilization. This problem is complicated by uncertainty about the current status and productivity of the resource being managed, and hence about the implications of...

A comparison of otolith microchemistry and genetic techniques for evaluation of stock structure of the jackass morwong Nemadactylus macropterus

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...

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...

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...

Second Australian National Prawn Seminar

Since the First Australian National Prawn Seminar in 1973, Australian prawn fisheries have grown in size and value to become Australia's most valuable fisheries resource. In the same period the number of people involved in the fishing industry, research and management has also increased. Major new...

Northern shark tagging study

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...

Interim monitoring of the 1995 eastern gemfish spawning run

Historically, monitoring of the eastern gemfish stock has been based on sampling at NSW fish markets, and carried out by NSW Fisheries Research Institute as part of its NSWs management responsibilities for the fishery. With the advent of AFMA, however, responsibility for monitoring of the fishery...
