Abstract
Ammonia-induced and its withdrawal-dependent changes in acetylcholinesterase (AChE) and catalase (CAT) of liver gill and skeletal muscle of Clarias batrachus (Linnaeus 1758) were investigated. AChE activity declined gradually in these tissues up to 35 days of ammonia exposure. In contrast CAT activity increased up to 7 days and thereafter it declined to some extent. Maximum effects of ammonia on CAT and AChE were on 7th and 35th day of treatment respectively. AChE activity declined maximally in gills (61) but CAT activity enhanced maximally in liver (1.6 fold). Withdrawal of ammonia from water for 14 days after 35 days of exposure indicated incomplete recovery in AChE activity. However withdrawal of ammonia showed complete reversal in CAT. Removal of ammonia from water may help in damage control. Since ammonia-induced neurotoxic (AChE) effect was more pronounced than antioxidative (CAT) response AChE may be used as an indicator of ammonia toxicity in aquaculture.
