Results and standing stock biomass estimates of finfish from the 2001 US AMLR bottom trawl survey of the South Shetland Islands (Subarea 48.1)
bottom trawl survey in March, 2001 of the South Shetland Islands. Information on species composition ... advisable. The potential role of habitat structure in demersal finfish assemblages in the South Shetland ... Survey. For most species, the standing stock has decreased slightly, although in most cases the 95 ... % confidence levels from the 2001 surveys were considerably decreased.
