The maximum biomass of these animals reaches from 1/8 to 1/10 part of the total weight of substratum. The calorific value of Orchestia was determined simultaneously with a bomb calorimeter and chemical method of combustion. The variability of calorific content within the size group of Orchestia from 1 to 120 mg was relatively constant during the year. Mean calorific value of dry matter have been equal 4.7 Kcal/g. Between the caloricity of unit of ash-free weight (y) and content of organic matter in the animals in percent (x) a straight line relation was found: y = 0.0945*x - 2.55. An increase of caloricity is connected with accumulation of the fat in the body and growth with age of animals.ru
