It is shown that the average daily diet values of the crab Menippe mercenaria depend on the power of the body weight of these animals and can be described by a parabolic equation. The maximum crab diet value is determined. The ratio of the maximum daily diet value to the average is approximately 3. When the crab feeds on fish (Opistonema oglinum), assimilation is very high and fluctuates within limits of 96.9 to 99.0. The calorific value of the dry ashless organic matter of the crab is 5 Kcal/g. The energy expended by crabs for respiration (energetic metabolism) is 18—55% (average 29.1%) of the total energy of the consumed food. When the diet is maximum the animals can satisfy fully the needs of the energetic metabolism in two weeks at the expense of the food energy, which is of great ecological significance for this animal species and has an adaptive character in connection with irregular feeding. On the strength of comparing calculated energetic balance parameters it is shown that these animals expend from 45 to 82% of assimilated food energy for the processes of growth and reproduction. The average coefficient of assimilated energy utilization for growth (К₂) is approximately 71%.
