The effects of thiobencarb (0.22 mg/l) on the intermediary metabolism of the European eel, Anguilla anguilla, and its recovery from intoxication were evaluated. Physiological measurements were made in plasma, muscle and liver of the eels during exposure and after an 8-day recovery period in noncontaminated water. Hyperglycemia was detected during exposure, while liver and muscle glycogen levels decreased markedly. Blood lipid values increased, however, a decrease of the lipidic reserves was determined in liver tissue. Mobilization of proteins was detected specially in muscle tissue. Most of the metabolic disorders persisted after eight days in clean water. The observed effects of thiobencarb on intermediate metabolism are discussed in relation to a stress syndrome, as an indicative status of the physiological adaptability of the fish to compensate pesticide stress.
