Download FAR 2021/64 Stock assessment of ling (Genypterus blacodes) in the Sub-Antarctic (LIN 5&6) for the 2020–21 fishing year

This report summarises a stock assessment of Sub-Antarctic ling (LIN 5&6, excluding LIN 6B) for the 2020–21 fishing year. The main indices of abundance were trawl surveys and the commercial longline standardised catch per unit effort series. Natural mortality was shown to be poorly estimated, with bias, and was hence assumed to be 0.18 y-1. The initial biomass was lower than in the previous assessment at about 187 350 t; stock status in 2021 was estimated at 71% B0.
