| Abstract: | A toxicity test with cadmium concentrations ranging from 0·1 to 100·0 mg Cd 1−1 was used to assess the effect of cadmium pretreatment on rainbow trout ( Salmo gairdneri Richardson) alevins. The median period of survival for fish pretreated at 0·01 mg Cd 1−1 was found to be increased at test concentrations up to 10mg Cd 1−1 compared with alevins pretreated with dilution water. However, at concentrations above 10mg Cd 1−1 pretreatment at 0·01 mg Cd 1−1 reduced the median period of survival. |
