Natural mortality rate in the mackerel icefish (Champscephalus gunnari) around South Georgia

Information on natural mortality rates of the mackerel icefish (Champsocephalus gunnari) from the period prior to known large-scale commercial harvesting is discussed. After careful consideration of the data and available methods, several errors are noted in earlier estimates. Unfortunately, because...
