Download FAR 2019/66 Stock assessment of hake (Merluccius australis) on the west coast of South Island (HAK 7) for the 2018–19 fishing year

This report presents the assessment of the WCSI hake fishery in 2018–19. It used catches and catch age composition data from the commercial trawl fishery, research trawl survey biomass index and age composition data, and biological parameters available in the scientific literature. The spawning stock biomass was estimated to have declined since 1990, reaching 17% of B0 in 2019. Three different parameterisations highlighted the sensitivities of this result to alternative assumptions.
