For a period of 83 days, results showed that the water quality, salinity, dissolved oxygen, temperature, pH, ammonia, nitrite and nitrate. There's absolutely no statistically significant difference (p> 0.05) part of the acid - base. The differences were statistically significant (p <0.05) in the growth of the fish in the density of 1000 per 35 cubic meters and the density of 3,000 per 35 cubic meters that averages. weight gain 237.63 ± 75.63, 86.14 ± 33.00 (g a), average growth per day 2.86 ± 0.91, 1.04 ± 0.40, the percentage rate of exchange feed 0.76 ± 0.07, 2.23 ± 0.19, the survival rate. 97.20 ± 1.97, 91.69 ± 2.68, respectively, the difference is statistically significant (p <0.05) on the percentage of extra weight 40.24 ± 9.11, 26.11 ± 9.31 percent, respectively, a difference there. significant (p> 0.05).
