Individual growth rate and age at first sexual maturity in Atlantic salmon
Nævdal, Gunnar; Holm, Marianne; Lerøy, Rita; Møller, Dag (Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1978)Growth rates and possible connection between growth rate and age at maturation were studied on individually tagged salmon originating from different river populations. Great variations in growth rate and in age at first ... -
