Description: Fishery specific harvest strategies and harvest control rules are set in accordance with the Commonwealth Harvest Strategy Policy. The Harvest Strategy Policy requires a rebuilding strategy be implemented for stocks below a defined limit reference point. Setting a TAC of zero is one option, however, for multi species fisheries, a catch of zero can be difficult to achieve as species may be unintentionally caught when operators are targeting species that are associated with the depleted species. Bycatch/Byproduct TACs must be set in a way that allows the stock to rebuild within the timeframes of the rebuilding strategy.

Key Words: Eastern Gemfish, School Shark, Blue Warehou, rebuilding, incidental catches, by-catch TAC, by-catch, by-product, avoidance, companion species, risk assessment
 
Summary: Incidental catches of species whilst fishing includes the take of both quota and non-quota species. Generally these species are relatively data poor but the Harvest Strategy Policy still requires a determination of whether these species are at risk of overfishing.
 
This project sought to develop guidelines and tests to determine if incidental catch levels for any species are likely to be unsustainable or contrary to the principles of the Harvest Strategy Policy, with particular reference to species under rebuilding strategies (providing case examples).
