Effects of effluents on juvenile chinook salmon Oncorhynchus tshawytscha were studied in six laboratory streams. Primary effluent (KME) from mill A reduced salmon production at a concentration of 1.5% by volume (0.2 x 96h TL50) but not at 0.5% (0.07 x 96 h TL50). Fall and spring exposure to stabilized kraft effluent (SKME) from mill A at 1.5% reduced salmon production, while in summer experiments, fish production was enhanced at concentrations of up to 4% for mill A and up to 7.5% for mill B. Thus, production values varied with the source and extent of treatment of effluent and perhaps with season. Fish growth was related to food density during some experiments.
