Northcote, T. G. (1978). Migratory strategies and production in freshwater fishes. Pages 326-359 in S. D. Gerking, ed. Ecology of Freshwater Fish Production, Blackwell Science, Oxford (England).

There are many mechanisms for increasing survival, growth, abundance and hence production of freshwater fish which can result from their migratory behaviour. The importance of migrations seems assured as an adaptive feature of major significance in production of freshwater fish, especially in environments subject to sharp temporal fluctuations or to marked spatial patches in habitat fertility. Studies to determine more precisely the degree to which these phases of migration regulate production are badly needed together with the extent to which they can purposefully be used to better exploit the phenomenon in production of species useful to man.
