Abstract
The absolute changes in fat, protein, water and free and esterified cholesterol for the entire body of standard male and female sockeye salmon (Oncorhynchus nerka) during the Fraser River spawning migration are discussed.The data were obtained for twelve groups of males and twelve groups of females, totalling 216 fish. The fish were caught at three locations: before entering the river, 250 miles up the river, and at one of the spawning grounds 715 miles from the first sampling station.
