Cardiovascular and respiratory changes in eel, Anguilla anguilla L. during exposure to lethal doses of lindane at different water temperatures

Abstract

Heart rate and ventilation frequency were monitored in ell exposed to lethal doses of lindane at different water temperatures. A simultaneous bradycardia and hyperventilation followed by a decrease in the ventilation rate occured after exposure to lindane. It is concluded that lindane kills fish by internal hypoxia induced by damage to the gills.
