Habitat and fisheries production in the South East Fishery ecosystem

In 1994 CSIRO and FRDC started a 5-year ecosystem study of the southeastern Australian continental shelf. Fisheries management in this area is currently based on individual species. Our goal was to identify ecosystem features that could extend the data available to manage the fisheries in this...

Development of a sustainable industry-based observation system for blue grenadier at the primary spawning sites

Blue grenadier has the highest current TAC among SEF species and has two separate fisheries that target primarily either sub-adult fish year-round or mature adults in winter spawning aggregations. The sustainability of the fishery would be greatly enhanced with regular (sustained) monitoring of...

Data

Objectives

1. Computerise all fishery data from Soviet research cruies in Australian waters, 1963-1975: species composition by trawl length frequency, maturity, and stomach contensts data.
2. Validate and update species identification for species in instances where the identification os in doubt, based on cruise material
3. Archive the data in the AFZIS database
4. Analyse the data for patterns of distribution and relative abundance for major species

Development of the egg production method to assess the blue grenadier stock in the South East Fishery

The blue grenadier stock is potentially the largest fish stock in the SEF, and following the decline in quota of orange roughy, the need to assess its potential became urgent. The stock has been surveyed using traditional trawl methods and acoustics, but both methods provide only 'snapshot'...
