A revised estimate of short-term yield for the mackerel icefish (Champsocephalus gunnari) off Heard Island based on a trawl survey in 1998
Abstract: A random stratified trawl survey of Mackerel icefish in 2 populations (Plateau and ... Shell Bank) in the vicinity of Heard Island enabled a revised estimate of yield for the coming 2 seasons ... population. Unlike the previous 3 years, the Age 2 cohort in 1998 is very weak and is expected to contribute ... little to the biomass in subsequent years. If recruitment to Age 2 in 1999 is also weak then the fishery ...
