IDENTIFICATION

SCIENTIFIC NAME(s)

Macruronus novaezelandiae

SPECIES NAME(s)

Blue grenadier, hoki

COMMON NAMES

Whiptail, New Zealand straptail, Blue hake

There are at least two separate stocks of Blue Grenadier ( Macruronus novaezelandiae ) in the Southern and Eastern Scalefish and Shark Fishery (Wilson et al. 2010). Comparative analysis of otolith chemistry and shape indicates two separate biological stocks: one in the region of the Great Australian Bight Trawl Sector (Commonwealth) and the other in the region of the Commonwealth Trawl Sector. There is some evidence that Blue Grenadier from the western Tasmanian and eastern Bass Strait regions of the Commonwealth Trawl Sector may constitute separate substocks, but these are currently assessed and managed as a single Commonwealth Trawl Sector stock (Penneya and Moore 2014).

Catches from the Great Australian Bight Trawl Sector are currently small and are from a different stock than exists off western Victoria and Tasmania, where the bulk of the catch is taken. Blue grenadier from western and eastern Bass Strait regions are unlikely to be part of one highly mixed south eastern Australian stock (Daume et al. 2015).
