Abstract
The vertical distributions of Calanoides acutus, Calanus propinquus and Rhinicalanus gigas have been studied during Cruises I and II of the R.V. “Ob” in the Indian sector of the Southern Ocean. During the spawning period, all 3 species reveal the highest concentrations, and occupy the highest positions in the water column. During the period of feeding and growth, they begin slowly to disperse and to descend to greater depths. In spring, the populations ascend again to the water surface. In both seasons, later stages migrate first. Pronounced temperature gradients may prevent the ascent, and result in the breeding and subsequent growth of the new generation occurring in subsurface waters. Details of the vertical distributions of populations depend on their seasonal state and the local hydrology.
