Summary
Based on results obtained during Polish marine Antarctic expeditions to the Atlantic sector, an attempt is made to present a conception concerning a mechanism of formation of krill concentrations in areas of meanders and current eddies. According to this conception, the mechanical factors (currents) cause the permanent inflow of animals to the regions of concentration and at the same time the behavioral factors (specific reactions to the turbulent water flow and the instinct of shoal formation) make krill stay and congregate in such regions. It was observed that larger quantities of krill occur in the areas of hydrological fronts, meanders, and current eddies, especially in regions characterized by high gradients of current velocity. It was found, on the basis of hydroacoustic measurements, that krill patches occurring in their concentration regions, are of larger size and are characterized by greater krill quantities than those occurring beyond the limits of such regions.
