Attempts at a quantitative estimate by trawl sampling of distribution of postlarval and juvenile notothenioids (Pisces, Perciformes) in relation to environmental conditions in the Antarctic Peninsula region during SIBEX 1983-84
During the SIBEX 1983-84 programme, an attempt was made at a quantitative estimate of the distribution of postlarval and juvenile fish north of the South Shetland Islands and the Palmer Archipelago, and in the Bransfield Straits by means of a 368-mesh sampling trawl, designed especially for this pro...
