摘要：. A bioenergetics model was used to calculate the daily energy requirement (daily food ration) of the mysid shrimp Neomysis integer (Crustacea, Mysidacea) in the Vistula Lagoon. The growth rate defined as production (P), respiration (R) and egestion (F) was measured and the daily energy requirement (food ration) was calculated as the following sum: C = P + R + F. The dependence of the food ration on the body weight of N. integer was determined. It was confirmed that the amount of food consumed by the population of this species in late spring is half of that consumed by the smelt population during the same period.
