The 2013 annual random stratified trawl survey to estimate the abundance of Dissostichus eleginoides and Champsocephalus gunnari in the waters of Heard Island (Division 58.5.2)
(HIMI) was completed during April of 2013. The catches of D. eleginoides for 2013 were half that of 2012 ... invertebrates. Catches of individual invertebrate taxa were generally much lower than in previous years. Lengths ... and biological measurements were taken for 13,000 fish, 276 pairs of otoliths collected and 179 ... .
