In July 2006, the Great Australian Bight Industry Association (GABIA) discussed the need for further research to assess the stock structure of blue grenadier between the GAB and other fisheries, particularly the West Tasmanian region of the CTF. With total allowable catches for blue grenadier in the CTF under review, GABIA commented that it is very important for both the Great Australian Bight Trawl Fishery (GABTF) operators and management (AFMA) to better understand grenadier stock structure. GABIA suggested that assessing the stock structure of blue grenadier was one of the highest of priorities if it was going to be robust and likely to show differences if they exist. This view was taken too and noted by GABMAC. AFMA also support the need for this research - determining the stock structure of blue grenadier is a very high priority for management, and results of this project (whatever they are) will influence the management of blue grenadier in the GABTF, with the two most likely options being a global TAC apportioned between the GABTF and SETF or separate management of stocks in each zone. In short, both industry and management support the need for research to assess the stock structure of blue grenadier between the Great Australian Bite and Commonwealth trawl fisheries.
