Abstract

The purpose of this study was to determine the effect of molluscicide “niclosamide” on mortality of tilapia (Oreochromis niloticus) and determine the concentration of molluscicide “niclosamide” that are most toxic to tilapia (Oreochromis niloticus) as well as LC50. The experiment assigned under Completely Randomized Design (CRD) with 7 treatments (P1 = 0.00 mg / L as a control, P2 = 0.15 mg / L, P3 = 0.30 mg / L, P4 = 0.45 mg /, 0.60 mg / L, P6 = 0.75 mg / L, and P7 = 0.90 mg / L) and 3 replications. Based on analysis variance, its found that molluscicide “niclosamide” effect mortality of tilapia and the most toxic concentration molluscicide “niclosamide” as well as LC50 is 0,89 mg/L. Water quality parameters (temperature, DO, and pH) were in the range of optimum for tilapia (Oreochromis niloticus).
