TY - JOUR N2 - Studies were carried out in the region of southern. Drake Passage and Bransfield Strait in February and March 1981. The relation occurring between the alimentary tract filling (ATF) and the quantity of chlorophyll α integrated within the range of 0-150 m water-layer may be described by Ivlev's equation expressing the amount of the food ration in relation to food concentration. The ATF value increases in large individuals and is proportional to their body weight. The daily rythm of krill feeding, expressed by ATF, depends on the quantities of food in the environment.
