Sodium fluoride induce alterations in glycogen metabolism in freshwater catfish, Clarias batrachus (Linn.)

Abstract

Effect of fluoride toxicity on glycogen metabolism in fresh water catfish Clarias batrachus was evaluated after their exposure to two sublethal concentrations of fluoride (35 mg F ion/L and 70 mg F ion/L) for 60 days and 90 days. Alterations in glycogen content in muscle, liver, and testis tissues were recorded. The insignificant decreased level of glycogen content was recorded in muscle and liver tissues at lower concentration of F in both durations. However its elevated level was recorded at higher concentration of F in both tissues at both durations. The duration and concentration dependent depleted glycogen level was recorded significant (P
