NEW RESULTS ON THE FISH AND SHRIMP FAUNA OF THE WEDDELL SEA AND LAZAREV SEA (ANTARCTIC)
Abstract: A total of 151 demersal fishes and 555 shrimps were recorded on 1785 photographs which represent 1607 m2 sea floor of the shelf and upper slope of the Weddell Sea (Halley Bay near-shore area) and of the Lazarev Sea. The Lazarev Sea showed a high number of species (24) and an average abunda...

The Lazarev Sea showed a high number of species (24) and an average abundance of 7.24 nI100 m2. In the Halley Bay near-shore area only 11 species were found, however the abundance was high with 15.66 d l 0 0 m2. The species composition of these areas was compared using cluster analysis with previous results from adjacent areas. The Lazarev Sea was combined with the Halley Bay near-shore and the Kapp Nowegia areas to an area-cluster "north " which was different from an area-cluster "south " which comprised the Gould/Vahsel Bay, Vestkapp and Halley Bay off-shore areas. The most abundant species were Trematomus lepidorhinus in the Lazarev Sea and T. scotti in the Halley Bay near-shore area. The shrimp fauna was dominated in the Halley Bay near-shore area by Choris-mus antarcticus with an abundance of 33.45 d l 0 0 m2 whereas in the Lazarev Sea the three generally most abundant Antarctic shrimps C. antarcticus, Notoc-rangon antarcticus and Nematocarcinus lanceopes showed values between 1.25 and 3.42 d l 0 0 m2. Between the two shelf-inhabiting species C. antarcticus and N. antarcticus no difference in depth zonation was found. A small scale analysis of the occurrence of N. antarcticus and N. lanceopes indicated random disper-sion patterns at most investigated stations. 1.
