Lindane-induced changes in carbohydrate metabolism in Anguilla anguilla

1. Anguilla anguilla (L.) was exposed to a sublethal concentration of 0.167 ppm (0.25 of the 96-hr LC50) of lindane for 6, 12, 24, 48, 72 and 96 hr. 2. Changes in glycogen, glucose, pyruvate and lactate contents of liver and muscle after lindane exposure, were studied. 3. Muscle and liver glycogen levels decreased significantly during the exposure time. Muscle glucose values increased but on the other hand we found a decrease in those of liver. 4. Muscle and liver pyruvate content increased as did lactate levels in both tissues. 5. The observed effects of lindane on carbohydrate metabolism in fish are discussed in relation to acute stress syndrome.
