Includes bibliographical references (pages 95-96). "Characteristics of the adult Chinook and chum salmon populations of the Yukon River within Canada are described. Significant differences were found between the composition of the catch and the composition of the escapement in terms of sex and length. It is hypothesized that any change in the fishery from wheels to gillnet will result in greater catch of larger size fish and also of females. Such a change may have severe consequences on the reproductive capacity of the populations"--Abstract.
