Continuous-flow toxicity tests were conducted to determine the relative tolerances of newly hatched alevins, swim-up alevins, parr, and smolts of chinook salmon (Onocorhynchus tsawytscha) and steelhead (Salmo gairdneri) to cadmium, copper, and zinc. Alevins of both species were more resistant to cadmium and zinc than fish at other life stages were. Chinook salmon were slightly, but consistently more metal-tolerant than steelhead, and there was a general increase in tolerance as the fish developed through the swim-up, parr, and smolt stages. The 96 hr LC50 values for all four life stages are tabulated. (19 references, 5 tables)
