A revision of yield and catch controls for managing the mackerel icefish (Champsocephalus gunnari) fishery in the vicinity of Heard Island and McDonald Islands
Abstract: A recent 2000 survey of mackerel icefish in the vicinity of Heard Island enabled a ... revised estimate of yield for the coming 2 seasons. While the biomass of icefish appears lower than in ... previous years, it is dominated by a strong age 2 year class. Estimates of yield for the Heard Island ...
