Fisheries biology and interaction in the northern Australian small mackerel fishery

The small mackerels comprising school mackerel (Scomberomorus queenslandicus), spotted mackerel (S. munroi) and grey mackerel (S. semifasciatus) are important and valued species to recreational and commercial fishers in northern Australia. Prior to this project very little was known about the basic...

Review and assess stock assessment methods used in Australia

Stock assessments provide scientific advice in support of fisheries decision making. They involve fitting population dynamics models to fishery and monitoring data to provide estimates of time-trajectories of biomass and fishing mortality in absolute terms and relative to biological reference...

PROJECT STATUS:
COMPLETED

Biological and ecological research needed for the effective management of the bar-cheeked coral trout and the chinaman cod, including an investigation into the factors controlling sex-change in the serranids (cods, groupers and coral trout).

This study provides detailed biological and ecological information on the chinaman cod, Epinephelus rivulatus, and biological information on the bar-cheeked coral trout, Plectropomus maculatus, in West Australian waters. Both of these species are members of a large group of predatory fish known as...
