Recent work has shown that the metabolic responses of an organism to dietary properties are important determinants of the physiological processing of calories and nutrients. The effects of diet on the respiratory metabolism of a species is an especially important consideration since by far the majority of food energy assimilated goes to respiration. Rates of assimilation, growth efficiencies, and assimilation efficiencies are different for various dietary constituents. In the paper, the effects of diet on metabolic processes in Macrobrachiurn rosenbergii are reviewed from the perspective of diet evaluation. Physiological factors which are influenced by diet include metabolic rate (specific dynamic effect) growth, ammonia excretion, and the rate and efficiency of caloric assimilation.
