Some life history characteristics of coho salmon of Karluk River system
This paper contains data on some life history characteristics of the coho salmon of the Karluk River system, Kodiak Island, Alaska: age, fecundity, length, and egg size of adults; and migration charac-teristics, age, and size of smolts. The greater age at maturity of Karluk coho salmon (4 and 5 year...
