✦ Synopsis
Under the Antarctic coastal fast ice a light trap proved to be promising device for collecting not only planktonic animals, but also micronektonic animals like krill which have been rarely collected with tow nets. Sampling was conducted at night from May through November, 1984 in Kitano-ura Cove off the East Ongul Island in Ltttzow-Holm Bay. Design of the gear and the sampling procedure are described. A total of 37 samplings were made that resulted in the collection of seven species of copepods, eight species of amphipods, three forms of notothenid fish larvae, two species each of euphausiids and polychaetes, and one species each of mysid, cumacean, isopod and tanaid crustaceans. All were collected in satisfactory condition for laboratory experiments. During the winter Euphasia superba was found to be benthopelagic and it probably feeds on detritus on the sea floor at about 40 m depth under the ice.
