Development of more efficient traps for the North West Shelf fishery

1 A method was developed to rapidly assess the effectiveness of trap designs and identify the causes of differences in effectiveness. 2 Fish entry and escape probabilities are correlated across trap designs. The probabilities are very high for '0' and 'S' trap designs and are much lower for the 'Z'...

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...

Occurrence of toxic dinoflagellates in southern Tasmanian waters and possible implications for shellfish farming

Project number: 1986-084
Project Status:
Completed
Budget expenditure: $0.00
Principal Investigator: Gustaaf Hallegraeff
Organisation: CSIRO Oceans and Atmosphere Cleveland
Project start/end date: 27 Dec 1988 - 30 Dec 1988

FRDC

Objectives

1. Document seas abundance & spatial distribution dinoflagellates Gymnodinium catenatum, Dinphysis & D. fortii in S Tas waters.
2. Correlate abundance with variables.
3. Examine sediments for benthic cysts of G. catenatum. Document incidence in shellfish diet. Test shellfish for toxins

An investigation of the habitat requirements of post-puerulus stocks of western rock lobster (Panulirus Cygnus)

Project number: 1986-083
Project Status:
Completed
Budget expenditure: $0.00
Organisation: CSIRO Oceans and Atmosphere Cleveland
Project start/end date: 27 Jun 2000 - 30 Jun 2000
Contact:
FRDC

Objectives

1. Investigate natural habitat of post-puerulus western rock lobster
compare densities of p. settlement on artificial collectors & in natural habitats
2. Predict catches more accurately
enhance abundance & survival of post-p hence adult through knowledge of habitat requirements.
