Water quality study of the rearing of barramundi in level-2 density by using circulating water system for a period of 83 days, results found that the quality of water, dissolved oxygen, temperature, salinity, alkalinity, ammonia, nitrite and nitrate. Has ability to dress differently, no statistically significant (p > 0.05) acid-base section, there is a distinct difference statistically significant (p < 0.05) the growth of barramundi in density at the per 1,000 cubic metres and 35 in density that 3,000 WaSP 35 cubic meters. It found that average weight gain 237.63 ± 75.63, 86.14 ± 33.00 (grams), The average daily growth 2.86 ± 0.91 1.04 ± 0.40 percent, exchange rate, food is meat, 0.76 ± 0.07, 2.23 ± 0.19, survival rate, 1.97 ± ± 2.68 91.69 97.20 respectively. There is a distinct difference statistically significant (p < 0.05), when considering the percentage of increased weight 9.11, 40.24 percent 9.31 ± ± 26.11, respectively. There is a difference is not significant (p > 0.05).

The water quality of the farms were in density two class using recirculating systems 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).

Study on water quality of raising lates 2 density level by using circulating water system as the period 83 days. The results showed that the water quality. Salinity, dissolved oxygen, temperature, alkalinity, ammonia, nitrite and nitrate There is a different tune significantly P > 0.05) and acidity. The difference is statistically significant (also p < 0.05). In the growth of the lates density, 1 000 wasp 35 cubic meters, and in ความหนาแน่นที่ 3 000 wasps, 35 cubic meters. It was found that the average of the weight vector, increased 237.63 75.63 86.14 edge 33.00 (grams per), average growth per day 2.86± 0.91 1.04, convert, 0.40. Percent exchange rate and food conversion 0.76 edge, edge 0.07 2.23 0.19, survival rate 97.20 edge, edge 1.97 91.69 2.68 respectively. There were significant differences. (P < 0.05) when considering the percentage of weight gain 40.24 edge, edge 9.11 26.11 9.31 percent, respectively, have no significant difference. (P > 0.05).
