There were three objectives of the fish program: To assess the distribution and abundance of demersal fish on the shelf in the AFZ around Heard Island; to investigate the biology of the more important species; to take samples to determine by mitochondrial DNA (mtDNA) analysis whether the Heard Island Champsocephalus gunnari are a genetically distinct stock from those around Kerguelen Islands. The observations were taken from around Heard Island between May and June 1990. The data contains temperature and salinity data from a CTD survey and the results from various trawl surveys. The major species were Dissostichus eleginoides, macrourus holotrachys, Champsocephalus gunnari and Notothenia squamifrons. Numbers, species identity, guts and gonad data were obtained.
