Abstract
The number of young sockeye migrating seaward from Lakelse lake, B.C., was 557,000 (1946) and 373,000 (1947). From seeding estimates in the parent years per cent survivals of 1.1 and 0.4 have been calculated.Stomach analyses of 623 squawfish caught by gill nets in the late spring and summer months (1944–1947) show an average fish content of 83% by volume. Of this total fish content sockeye constitute 31%. The heavy losses in young sockeye could be attributed to the feeding of predacious fish and variation in sockeye survival may be a result of fluctuations in the abundance of "buffer" species.Keywords
