Spatial management within the NSW Ocean Trawl Fishery

The NSW Department of Primary Industries-Fisheries has outlined the results of a four-year trawl survey (2017-2020) aimed at evaluating spatial management provisions within the NSW Ocean Trawl Fishery (OTF) and the potential for these to be adapted to deal with tactical challenges associated with...

Predicting the impacts of shifting recreational fishing effort towards inshore species

The project outputs have led to the following outcomes: 1. A model has been developed enabling reliable estimation of mortality of fish species that undertake size-related, unidirectional, offshore movements from age and length data. This new modelling approach is likely to be applicable to stocks...

Summary

The prawn fishing industry in the Gulf of Carpentaria is worth $100 million/year and a large proportion of this is from catches of banana prawns. In one stage of their complex life history, banana prawn larvae are carried by ocean currents from their spawning grounds to the estuarine nursery areas.

The aim of this project was to define the currents that carry the larvae so that the life history can be more fully understood and various biological hypothesis concerning the banana prawn and in particular the behaviour of larvae can be fully tested. To achieve these goals a mixture of field work and theoretical modelling and cooperation between physical oceanographers and fisheries biologists was required.
