К методике расчета суточного рациона питания балтийского шпрота
The results of the investigations on sprat feeding carried out at 7 daily stations in the Eastern and South-Eastern Baltic within the feeding periods (July - September) are given for the years 1978 - 1982. A distinct daily rhythm in sprat feeding was noted with its maximum in the evening and minimum in the morning. Close ties between the stomach content indices within the period of maximum food amount in the stomachs and diets were revealed (r = 0.90). It was marked that in the period from 7 p.m. to 11 p.m. the food amount in the stomachs constituted 19.2 % of the total daily ration.
