Improving on Polyculture Eels (Anguilla bicolor) and Nile Tilapia (Oreocromis niloticus) Using Artificial Feed for Growth and Survival Rate

The study was conducted to evaluate to mix combination different combinations of eels and nile tilapias on the growth and survival. The material used eels ( A. bicolor ) 5-7.95 ± 0.025 cm, and used mix were 5 and 10 indivs nile tilapia/m 2 . that used artificial feed of vitamin E at a dose of 3% per biomass per day. An experimental randomized completely design was used with 4 treatments and 3 replications. The treatments were T1 (5 indivs/m 2 eels and 5 indivs of nile tilapia/m 2 ), T2 (10 indivls/m 2 eels and nile tilapia 5 indivs/m 2 ), T3 (5 indvs/m 2 eels and nile tilapia 10 indivs/m 2 nile tilapia, T4 (given 10 indivs/m 2 eels and given 10 indivs/m 2 nile tilapia. The data obtained was the absolute weight of data growth, survival, FCR, and water quality data ( pH, O 2 , NO 2 , etc) and were analyzed by analysis of variance. The experimental results showed significant effect (P <0.05) on the growth and survival Eels and nile tilapia. Polyculture of in eels and nile tilapia can increase of the highest absolute growth obtained from T4 treatment (187.85 ± 0.9 g), nile tilapia (60.65 ± 0.95 g).
