The random stratified trawl survey to estimate the abundance of Dissostichus eleginoides and Champsocephalus gunnari in the waters of Heard Island (Division 58.5.2) for 2016
April, with the completion of 163 stations. The survey was conducted for the second year on the FV Atlas ... survey, but with a new set of randomly selected station points. The calculated density of D. eleginoides ... was half that of 2015 but similar to that of the long-term average for the survey. The C. gunnari ... density was five times that of 2015 and nearly three times the average. For the managed bycatch species ...
