Predation, yield, and ecological efficiency in aquatic food chains

Ecological efficiency can be defined in terms of the rate of predation, the turnover time or inverse of the specific rate of increase of the biomass and the gross production efficiency, which may be approximated in short-term experiments by the gross growth efficiency. The ratio of the biomasses of 2 successive trophic stages of a food chain appears to be the same as the ecological efficiency, corrected by the ratio of the predation rates involved.
