事实证明，在南极沿海的快冰下，捕光器不仅是一种很有前途的捕获浮游生物的装置，而且还可以捕获像磷虾这样很少用两张网捕获的微浮游动物。1984年5月至11月，在Lutzow-Holm湾东Ongul岛附近的Kitano-ura湾进行了夜间采样。介绍了齿轮的设计和取样过程。共采集标本37份，共收集桡足类7种，片足类8种，梭鱼幼鱼3种，大鳞目和多毛纲各2种，甲壳类、cumac纲、等足类和tanaid类各1种。所有标本均收集完好，可用于实验室实验。在冬季，人们发现Euphasia superba是底栖动物，它可能以冰下约40米深的海底碎屑为食。
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 two nets. Sampling was conducted at night from May through November, 1984 in Kitano-ura Cove off the East Ongul Island in Lutzow-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.
