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.


1. Run sea trials to compare catch composition of "standard" GABTF net design with the full T-90 net design
2. Obtain preliminary quantitative estimates comparing target species catch composition of each net design
3. Obtain preliminary quantitative estimates comparing bycatch species catch composition of each net design
4. Quantitatively compare and assess the towing efficiency of each net design
5. Qualitatively assess and compare differences in fish quality among net designs
6. Effectively convert the results into tangible benefits for the GABTF and AFMA's Bycatch Reduction Program
