Abstract

Tilapia and catfish are freshwater fish commodities that are widely cultivated by the community because of their relatively easy maintenance, low cost, and short time. The quality of the cultivation water environment is an important factor and influences the growth performance and life of these commodities. This study aimed to analyze the growth performance of tilapia and catfish fry cultivated with the addition or supplementation of bio-enzymes with different concentrations in the maintenance water. This study used an experimental method with three treatments: control (without bio-enzymes), 500 ml/900 L or 0.6 ml/L bio-enzymes, and 1000 ml/900 L or 1.1 ml/L bio-enzymes. The results illustrate that bio-enzyme supplementation into tilapia fry ponds compared to the control treatment without bio-enzymes showed a higher contribution to weight growth than length growth. The opposite occurred for catfish fry, namely bio-enzyme supplementation into catfish fry ponds compared to the control without bio-enzymes showed a higher contribution to length growth than weight growth. Supplementation with 500 ml of bio-enzyme resulted in the highest absolute weight growth of tilapia fry, which was 16.95 g with a daily weight growth rate of 0.42 g/day and a specific weight growth rate of 3.35% and 100% survival rate. Supplementation with 500 ml of bio-enzyme resulted in the highest absolute length growth of catfish fry, which was 9.20 cm with a daily length growth rate of 0.23 cm/day and a specific length growth rate of 2.23% and 100% survival rate. In agribusiness perspective, only tilapia in consumption size (at 135 days old) treated with bio-enzymes (500 ml and 1000 ml) were recommended for sale, particularly in consumption size. Meanwhile, for catfish, only in fingerlings phase were decommended for selling with treatment bio-enzyme 500 ml.
