In this study, toxic effects of fish-seed (Anamirta cocculus) on carp (Cyprinus carpio) was investigated. Powdered fish-seed was applied at concentrations of 1, 2, 3, 4, 5, 7.5, 10, 15, 20, 30, 40, 50, 75 and 100 ppm. Temperature, pH, hardness and dissolved oxygen of water in aquariums used in the study were also measured. Although, no any behavioral changes were observed at the concentration of 1, 2, 3 and 4 ppm, fish became narcotized at higher concentrations of fish-seed. Between 5-50 ppm concentration, gradual decrease was observed in activity of fish. After 50 ppm concentration, fish become narcotized and inactive.
