Abstract
The effects of the McNary Dam transportation system on emigrating fall and spring chinook smolts were evaluated using physiological indices of stress (e.g., plasma cortisol, hepatic glycogen, leucocrit, interrenal cell nuclear diameter) and performance tests (e.g., saltwater challenge, secondary stress challenge, disease resistance). Controlled experiments were conducted in a hatchery environment to characterize the fishes' physiological responses to stress, and disease resistance to allow a basis for judging the nature of the stress experienced by smolts at McNary Dam. 55 figs., 3 tabs.Keywords
