The production rate varied between 2.89 and 3.56 gm⁻² yr⁻¹ in which the half were produced by 0+ age group. As compared with the production rate of other freshwater fishes inhabiting rivers, ponds and lakes in the world, the production rate was rather small in the stream. The cause of small production rate in the fish population was discussed in the relation to abiotic environments, population density and social behaviour.}, pages = {69--88}, title = {渓流域におけるアマゴOncorhynchus rhodurusの生産}, volume = {9}, year = {1982} }
