Abstract
Fentin acetate is used as a pesticide in rice fields to eradicate pests. Research with physiological factors approach is expected to increase the survival rate and growth performances of tilapia. The purpose of this study was to determine the impact of different concentrations of fentin acetate on the biological performance and hematological characteristics of tilapia (Oreochromis niloticus). The research used 16 rice fields with a 30 m2 each (6 x 5 m). The research design used a completely randomized design with four treatments and three replications: A. 0.00 g L−1, B. 0.375 g L−1, C. 0.75 g L−1 and D. 1.5 g L−1. The results showed that treatment C resulted in the best growth of tilapia. It was noted that absolute weight gain, daily growth rate and productivity were significantly different (P<0.05) with treatments A, B and D. The highest value in treatment C were 20.53 g (absolute weight gain), 5.43 (daily growth rate) and 501.58 g (productivity). The survival rate in treatments B and C were not significantly different (P>0.05) as well as treatments A and D. The concentration of molluscicide fentin acetate at a dose of 0.75 g/L affected the decrease in the hematological characteristics of tilapia.
