In an isolating experiment on feeding only on arthropods of terrestrial origin, the potential of their consumption by amphipods from a fishless water-course is studied. The data obtained confirm the hypothesis that, on the basis of experiments on feeding exclusively on arthropods, it is possible to determine the maximum proportion of their biomass that selected consumers are able to utilize. The results of such works can be used to quantitative assessment of the level of possible losses of allochthonous matter and energy for the recipient communities of waterbodies due to feeding activity of consumers from their tributaries. Assessments of this kind may be relevant when deciding on the food availability for juvenile salmonids, inhabiting recipient waterbodies.
