| 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. |
