Abstract

The physiological effect of cold shock on Labeo rohita is studied in laboratory
condition. Juveniles of L. rohita of average weight and length, 14.5 g and 130
mm respectively) were acclimatized and subjected to cold shock. A significant
decrease occurred in anterior kidney ascorbic acid level. There was a rise in
plasma cortisol with in 20 minutes after the shock. Plasma chloride levels decreased
significantly but subsequently recovered. Plasma glucose level increased
due to glycogenolysis in muscle and liver. Plasma lactic acid level increased and
persisted upto 24 hours of recovery.
