A preliminary assessment for mackerel icefish ( Champsocephalus gunnari ) in Division 58.5.2, based on results from the 2018 random stratified trawl survey
The annual random stratified trawl survey was undertaken in Division 58.5.2 in the vicinity of Heard Island and McDonald Islands during April 2018. This paper provides an updated growth model and a preliminary assessment for mackerel icefish ( Champsocephalus gunnari ) population structure, abundanc...
