SESSF Monitoring and Assessment – Strategic Review
Tactical Research Fund: Empowering Industry R&D: Trials of T90 mesh configuration for bycatch reduction and more efficient fishing in the Great Australian Bight Trawl Fishery
There is an obvious need to reduce bycatch in the fishery consistent with mandatory legislative and policy requirements (EPBC and FMA) and to develop more efficient harvest protocols. Consistent with this, GABIA has provided full support for the introduction of T90 mesh into their fishery through the mandatory use of T90 extensions and/or codends from 1 January 2007. Potentially, even greater benefits are possible with a move to T90 gear from the wingends to codend. Such nets have been tested and shown to be effective in some Icelandic fisheries.
Modifications to gear (particularly the very recent move to full T90 nets in some overseas fisheries) have been shown in other fisheries to be effective in reducing fuel consumption consistent with the need to reduce operating costs and to reduce greenhouse gas emissions in the fishing industry. This proposal aligns to priorities of reducing environmental impacts of trawl fisheries and of increasing operating efficiency and industry profitability.

Effects of Trawling Subprogram: assessment of bycatch in the Great Australian Bight Trawl Fishery
The GAB Management Advisory Committee (GABMAC) and the GAB Industry Association (GABIA) have raised concerns that they do not have the data necessary to assess the GABTF's compliance with ESD principles. If the core objectives of The National Policy on Fisheries Bycatch are to be implemented for the GABTF, there is an essential need for baseline data on bycatch to be gathered. Once this information is available, they will be able to determine if bycatch levels are acceptable or if there are particular times or regions in which the bycatch levels in the GABTF are deemed too high. When a comprehensive understanding of the nature of the bycatch issue in the GABTF is established, it will be then possible to investigate the most appropriate ways of reducing the levels of bycatch.
