Tide and current analysis of the Gulf of Carpentaria and its relation to banana prawn larval dispersion

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...

Tactical Research Fund: Development and deployment of sterile ‘Judas fish’ to assist carp eradication in Lake Sorell, Tasmania - surgical and chemical sterilisation

In a world first, the project successfully developed reliable procedures for surgical sterilization of male carp and demonstrated that these when deployed as sterile ‘Judas’ fish are as competent as male ‘Judas’ carp in betraying the locations of feral populations thus...

The influence of fish movement on regional fishery production and stock structure for South Australia's Snapper (Chrysophrys auratus) fishery

From 2007 onwards, South Australia’s snapper (Chrysophrys auratus) fishery underwent significant and unprecedented changes that impacted on the management of the fishery. This ultimately reflected our poor understanding of the movement behaviour of snapper and its consequences for...

Rock Lobster Post Harvest Subprogram: the effect of on-board cold water stunning on the survival and growth of caught and returned western rock lobsters (Panulirus cygnus)

The relative recapture rates of returned stunned and unstunned lobsters have been quantified. Apparently conflicting results were obtained from two different areas of the fishery, but the results were deemed inconclusive due to low numbers of recaptures from water surrounding the Southern Group of...

Development of Fish Health Indicators for the Gladstone Harbour Report Card

As the link between land and sea environments, estuaries are complex ecosystems vulnerable to human impacts, which directly and indirectly affect plants and animals, including fish. Fish are key biological indicators of environmental contamination, as they are water breathers, common in aquatic...

Need

The performance report on the Pilbara Trawl Fishery to Environment Australia reported a dolphin catch of approximately 50 per year. The initial reaction of EA to this level of dolphin catch indicated that continued exports from this fishery could be in jeopardy, making it necessary to reduce the dolphin mortality. Industry are aware of this need and are willing to participate in trials.

Objectives

1. Determine the occurrence of dolphins swimming into the net on vessels with exclusion grids, compared to vessels without grids, and to determine the behaviour and fate of the animals encountering the grid.
2. Determine the occurrence of dolphins swimming into the net on vessels with pingers, compared to vessels without pingers.
3. Determine the mortality rate of dolphins on trawls where pingers or grids are deployed compared to trawls without mitigation devices.
