Abstract
Tinca tinca were exposed to acute lethal and chronic sublethal treatments each of Hg, Cd and Ph. Behavioural abnormalities, such as increased breathing, frequent surfacing and hypo/hyper-activity were observed in one or in another exposure of each heavy metal. Death mimicry was observed in acute lethal treatment of cadmium and increased feeding was recorded in chronic sublethal treatments of lead. In mercury and cadmium treatments erratic movement, loss of equilibrium, lethargy, unconsciousness and vertical position were recorded. Mortality was observed in acute lethal treatments only.
