GROUNDFISH SURVEY IN CCAMLR SUB-AREA 48.3 IN APRIL 2008 WITH PRELIMINARY ASSESSMENT OF MACKEREL ICEFISH
(2003), the biomass of mackerel icefish was estimated to be 80,426 tonnes, with a lower 1-sided 95% CI ... 2007/08 catch that remained after the survey (1709 tonnnes) will be taken. Scenario 1, which included ... was successful. The icefish appeared to be dispersed, which is amenable to a random trawl survey ...
