Standing stock biomass of eight species of finfish around Elephant Island and the lower South Shetland Islands (Subarea 48.1) from the 1998 US AMLR bottom trawl survey

The United States Antarctic Marine Living Resources (U.S. AMLR) program conducted bottom trawl surveys in March, 1998 of the two major regions of the South Shetland Islands: Elephant Island and the lower South Shetland Islands from King George Island to Livingston Island. Estimates of total stock biomass and spawning stock biomass were computed for six species: Champsocephalus gunnari, Gobionotothen gibberifrons, Notothenia coriiceps, Chaenocephalus aceratus, Chionodraco rastrospinosus, and Lepidonotothen squamifrons. Estimates of total stock biomass only were computed for two additional species: Lepidonotothen larseni and Notothenia rossii. Biomass was estimated for both regions separately, and combined as one system using previous and updated estimates of seabed areas for Elephant Island and the lower South Shetland Islands.
