Population dynamics and life-history plasticity of mackerel icefish ( Champsocephalus gunnari ) within the vicinity of Heard Island and the McDonald Islands
Mackerel icefish ( Champsocephalus gunnari )are found associated with sub-Antarctic islands andcontinental shelves in the Atlantic and Indian sectorsof the Southern Ocean between the Polar Front andthe Southern Boundary of the Antarctic CircumpolarCurrent. Mackerel icefish are one of the most common...
