Resistance of temperature tolerance ability of green sunfish to cadmium exposure
Fish are in intimate contact with their aqueous environment, and hence, are quickly susceptible to stressful changes in their chemical milieu. It is expected that stressful chemicals present in the external aquatic environment would induce observable physiological changes, even at sublethal concentrations. The authors reported that cadmium at LC5, LC10 and LC20 concentrations (of 96-h LC50) highly significantly decreased the temperature tolerance of red shiners Notropis lutrensis and fathead minnows, Pimephales promelas. Since sunfishes, family Centrarchidae appear to be more resistant to certain types of chemicals, they decided to employ similar methodology to test the effects of cadmium on temperature tolerance of green sunfish, Lepomis cyanellus. The literature and research in the laboratory led them to hypothesize that cadmium exposure would not reduce temperature tolerance as much as in a centrarchid such as green sunfish as in red shiners and fathead minnows.
