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...

A preliminary assessment of the genetic population structure of Asterias amurensis in Tasmania

Project number: 1993-246
Project Status:
Completed
Budget expenditure: $38,343.00
Principal Investigator: Bob Ward
Organisation: CSIRO Oceans and Atmosphere Cleveland
Project start/end date: 29 Jun 1993 - 31 Mar 1995
Contact:
FRDC

Objectives

1. Determine whether the introduced seastar is the southern sub-species, Japanese and Russian populations of Asterias amurensis versicolor or a northern sub-species
2. Determine whether the Tasmanian populations are derived from one or several introductions
3. Determine whether the invasion of Tasmanian waters has been accompanied by a loss of genetic variation with respect to native populations

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...

An Ichthyoplankton based analysis of the spawning distribution and stock structure of temperate Australian finfish species

Project number: 1992-019
Project Status:
Completed
Budget expenditure: $180,000.00
Principal Investigator: Ronald E. Thresher
Organisation: CSIRO Oceans and Atmosphere Cleveland
Project start/end date: 26 Sep 1992 - 30 Jun 1994
Contact:
FRDC

Objectives

1. To determine the number and locations of spawning grounds for the major commercial finfish species in temperate Australian waters.
2. To examine patterns of larval drift for indications of the distribution and number of nursery grounds for these species.
3. To apply microprobe and genetic techniques to larvae juveniles and adults to quantify the spread of individuals from spawning and nursery areas and the mixing of stocks.
4. To use these data to infer the stock structure of temperate Australian finfishes.
