Corydoras at the initial body weight of 0.44-0.51 g and total body length of 2.20-2.31 cm were used in this research. The research was conducted in two-factor factorial design. The first factor was the stocking density level (3000, 4500, 6000 fish/m 2) and the second factor was the water exchange level (50 and 100 % day-1). The result showed that specific growth rate of length and weight of fish were significantly different among treatments. There was interaction between stocking density and water exchange level in the specific growth rate. The highest value of specific length increase was 0.4±0.02 % day-1 and specific weight gain was 1.04±0.09 % day-1 , found at stocking density of 3000 fish/m 2 with 100 % day-1 of water exchange. There was no significant difference between survival rate of 3000 and 4500 fish/m 2 treatments at 94.81±0.64% and 98.33±1.44%, respectively. The range of water quality such as temperature, pH, dissolved oxygen, alkalinity, turbidity, ammonia, nitrate, and nitrite during rearing period were suitable for Corydoras fish culture. As a conclusion, the best stocking density for corydoras fish was 3000 fish/m 2 with 100 % day-1 of water exchange.

The research was located in the Cibadak district, Sukabumi West Java Indonesia. The water sampling method was carried out in two locations, namely a large settling pond and a small settling pond. Water quality parameters were analyzed such as pH, alkalinity, turbidity, total organic matter, and total ammonia nitrogen. The results showed that the water in both pond contents heavy metals. The heavy metals in the form were Mercury (Hg), Cadmium (Cd), Copper (Cu), Lead (Pb), Arsen (As), Ferrum (Fe), and Cromium (Cr6+) in the both settling ponds. However, in small ponds there was a higher Fe value so the water is yellowish. There is a difference in acidity showed in the two ponds, pH 3-4 in the small pond and the large pond pH 7-8. Total organic matter was higher in large pond. Small settling pond has a very low pH value, so they are classified as acidic waters and contain high iron content so they cannot be used for human needs or aquatic life. Large settling ponds can still be used for aquaculture activities.
