Abstract
The vertical distribution of eggs and larvae of the Antarctic Krill, Euphausia superba, was studied during January 1981 in the Scotia Sea. Nauplii were scattered over a wide range of depths, whereas metanauplii were found concentrated between 1000 and 500 m. Calyptopes were not found below 1000 m but large numbers were present in the upper 500 m, predominantly in the 100–30 m layer. The herbivorous copepod, Calanoides acutus, was confined closer to the surface. The omnivorous copepod, Metridia gerlachei, occurred at depths > 100 m, down to 500 m. It was the most abundant copepod found in the central Scotia Sea. In the eastern Weddell Sea, E. superba larvae occurred together with larvae of Euphausia crystallorophias which were more abundant. Euphausia superba larvae tended to congregate at greater depths (between 200 and 300 m) than those of E. crystallorophias which were most abundant near the surface.
