Antigonon leptopus Hook. and Arn. a new plant origin icthyotoxicant on Channa punctata Bloch, 1793 for aquaculture management

The present study was conducted to develop an ecofriendly and effective organo piscicide. Here piscicidal effect of locally available plant Antigonon leptopus Hook. and Arn. Against common freshwater air breathing predatory fish Chana punctatus Bloch,1793 and their behavioral changes were investigated. The test fish was exposed to five different concentrations of fresh leaves aqueous extract 10,20, …50ppm for toxicity test remaining one a control. Attempts had been made to access the impact of 24h LC100of the aqueous extract of A. leptopus leaves on the test fish Chana punctatus. To determine the LC100 of the leaf extracts, relationship between observed and expected rate of mortalities of the test fish and dose mortality relationships, Chi square and ANOVA tests were done. This study indicates that the leaf extract of the plant species may be used as potential organo piscicide to remove the unwanted weed fish species from the fish culture ponds as an environmentally safe and effective phyto piscicide necessary for aquaculture management.
