Need

Managers need to be provided with information that will ensure that fishing mortalities remain below the appropriate biological reference points for the key species.

To provide this information, knowledge is required of the relationship between fishing effort and fishing mortality. An experimental approach which provides a clearly measurable level of fishing mortality will achieve this. The fish in the 100-200m depth zone are schooling species and commercial effort will naturally be targeted on schools, so commercial catch rates cannot be used for the abundance measures required to calculate fishing mortality. There is a need therefore for survey fishing before and after the period of intense commercial fishing and for research personnel to oversee the survey fishing, gather samples and information on the survey cruises, process these at the laboratory and analyse the results. Monitoring of the fishing effort through research logbooks during the commercial fishing period is also required.

Objectives

1. To determine the relationship between fishing effort and fishing mortality for the key outer-shelf demersal scalefish species (principally Pristipomoides multidens) in the Pilbara fishery.
2. To document the distribution and abundance of adults and juveniles of major finfish species in the 100 to 200m depth zone off the Pilbara coast.
3. To provide industry and management with a range of options for sustainable exploitation of the deeper water fish resources of the Pilbara.

Seafood CRC: decision-support tools for economic optimisation of western rocklobster

The Western Rocklobster fishery was one of the first to be made limited entry with the number of licences restricted since 1963. Historically, the main focus of the assessment and management of the fishery has been on the status of the breeding stock to ensure biological sustainability. In the...

Characterisation of the inshore fish assemblages of the Pilbara and Kimberley coasts

The catches of the main fish species obtained by commercial, recreational and charter boat fishers along the Pilbara and Kimberley coasts have been determined by analysing the Department of Fisheries Western Australian Catch and Effort Database System (CAES), the results of a recreational creel...

Determination of the disease status of Western Australian commercial prawn stocks

There is little published information on the disease status of the prawns on the north-west shelf, yet these prawns (Fenneropenaeus merguiensis, Metapenaeus endeavouri, Penaeus esculentus and Melicertus latisulcatus) form the basis of a commercial fishery worth in excess of A$42 million in...

Enhancement of yabbie production from Western Australian farm dams

Farmers receive higher prices per kilo for large yabbies. Yabby farmers have reported that the majority of yabbies trapped from farm dams are below market size (< 30 g) and therefore of no economic value. In addition, farmers also report that while dams produce large yabbies when...

Developing novel remote camera approaches to assess and monitor the population status of Australian sea lions

This project trialled the use of remote cameras to monitor the relative abundance of Australian sea lions (ASLs, Neophoca cinerea) at three Western Australian (WA) breeding colonies. The research was undertaken by the Department of Primary Industries and Regional Development (DPIRD) to assess...
