Evaluating the costs and benefits of research on stock structure for management of the orange roughy fishery

This report describes a procedure for objectively comparing the likely returns from research programs, particularly those designed for fisheries management purposes. This procedure requires that the management objectives for the fishery are well defined, and that the research is directed at...

Review and update harvest strategy settings for the Commonwealth small pelagic fishery

This study undertook ecosystem and population modelling to evaluate and provide advice on the reference points (e.g. biomass depletion levels) and settings (e.g. exploitation rates) for the four main target species in the harvest strategy of the Commonwealth Small Pelagic Fishery (SPF) – Jack...

Catch-at-age, age at first spawning, historical changes in growth, and natural mortality of SBT: an integrated study of key uncertainties in population biology and dynamics of SBT, based on direct estimates of age from otoliths

The CCSBT has recognized for a number of years that a better understanding of the population biology and demographics of southern bluefin tuna (SBT) is necessary for improved population modeling and stock assessments. In 1996, the CCSBT Scientific Committee identified three areas where our...

Effects of seasonal and interannual variability of the ocean environment on recruitment to the fisheries of Western Australia

The relatively high catch of invertebrate species in Western Australia compared to finfish is in sharp contrast to other regions of the world where finfish production usually dominates. This low level of finfish production is primarily due to the Leeuwin Current which brings warm, low nutrient...
