A respirometer to measure the uptake efficiency of waterborne contaminants in fish

The construction and testing of an apparatus to standardize the measurement of uptake efficiency of both waterborne contaminants and oxygen in conjunction with metabolic rate of unanesthetized rainbow trout ( Salmo gairdneri) of 60–110 g are described. Using radiolabeled methylmercury as the contami...

Zusammenfassung:The construction and testing of an apparatus to standardize the measurement of uptake efficiency of both waterborne contaminants and oxygen in conjunction with metabolic rate of unanesthetized rainbow trout ( Salmo gairdneri) of 60–110 g are described. Using radiolabeled methylmercury as the contaminant the apparatus gave consistent results. The uptake efficiency of methylmercury was found to be 7.1 ± 0.14% when oxygen uptake efficiency was 53.6 ± 0.01% and metabolic rate was above routine but within the scope of the fish at 9.26 ± 1.43 μg O 2 min −1 g −0.8.
