Background

Blue Warehou is a highly mobile schooling species, occurring seasonally with inter-annual variability in Tasmanian inshore waters, mostly likely in association with prevailing oceanographic conditions and the availability of prey species (mostly salps). A small recreational gillnet fishery for Blue Warehou represents < 10% of the total annual harvest of this species in Tasmanian waters. The Blue Warehou stock has been classified as Depleted (Overfished) since 2008, despite the Blue Warehou Stock Rebuilding Strategy that has been in place since then (AFMA 2014). The stock rebuilding strategy established Blue Warehou as an incidental catch only species and the Commonwealth Total Annual Catch at the Commonwealth level has decreased a number of times.
