Abstract


The objectives of this research were to know the effects of zeolite on the water quality and the growth of catfish. Catfishes were cultured in fiberglass containers (±24 l) with 5-10% of water exchange/container/day, for 3 months. The stocking density was 8 fishes/container (3 fishes/l water). Zeolite was added at 0, 125, 250, 500 mg/l/month.

Result of this experiment indicated that zeolite at 125, 250, 500, mg/l/month decreased free CO2, alkalinity and NH3 of water during 3 months culture of catfish. The body weight increasment of catfish cultured in treated water with zeolit at 125, 250, 500 mg/l/month were 188, 195, and 222 g, respectively, which were higher than that of catfish cultured in untreated water.
