ACUTE TOXICITY OF ALBIZIA PROCERA (ROXB.) BENTH.BARK EXTRACT ON CARASSIUS AURATUSAND DANIO RERIOFISHES

This study aims to determine the lethal concentration (LC50) of Albizia procera (Roxb.) Benth. bark extract on two different fish species; Carassius auratus (Gold fish) and Danio rerio (Zebra fish) through the acute toxicity test, focusing on the concentration-dependent changes in fishes for 24-hours exposure in-aquaria. The acute toxicity study conducted on C. auratus and D. reriofishes in-aquariarevealed that the A. procera bark extract was effective to the fish under test, beginning with a dosage 150 mg/L and 100 mg/L for C. auratus and D. rerio. The fishes that were exposed to the fresh bark extract of A. procera displayed signs of abnormal behaviours like erratic swimming patterns, positional imbalance, excessive mucus production, surface gulping of air, and settles at the bottom motionless before death. While, the fishes in the control aquarium, without A. procera bark extract survived the entire 24-hours exposure period. Among the two different fish species used, the bark extract of A. procera showed remarkable piscicidal activities on D. rerio as compared to C. auratus. The LC50 values of the aqueous bark extract of A.procera for C. auratus and D. reriofisheswere 243.05 mg/L and 169.78 mg/L. Also, the LC50 of the methanol bark extract of A. procera for C. auratusfishes was found to be 193.95 mg/L. A high concentration range of A. proceraextract has the potential to become toxic to fishes, hence this study was done to identify the safety margin of A.
