Abstract

The pH of waters is one of external factors that is important for succesfull of hatching percentage of fish eggs. The pH stimulates the chorionase enzyme become more active that can softens the egg chorion so the eggs are easy to hatch. The aim of this study was to determine the optimum pH value for hatching of catfish eggs based on the hatching percentage and the hatching time. This research has been conducted in Fisheries Basic Laboratory, Department of Aquaculture, Department of Fisheries, Agriculture Faculty, Universitas Sriwijaya from August 31st to September 16th, 2019. The research method used Completely Randomized Design with five treatments and 3 replications. The treatments are P1 (pH of 5±0,2), P2 (pH of 6±0,2), P3 (pH of 7±0,2), P4 (pH of 8±0,2) dan P5 (pH of 9±0,2). The results showed that different value of water pH gave significant effect on hatching percentage, hatching time and survival rate of catfish larvae but did not significant effect on percentage of abnormal larva. The highest hatching percentage 80.33 % was in treatment of pH 7 ± 0.2 (P3), the fastest hatching time 21.59 hours was in treatment of pH 8 ± 0.2 (P4), the highest survival rate of catfish larvae 99.44 % was in treatment of pH 7 ± 0.2 (P3) and the highest percentage of abnormal larvae 2.22 % was in treatment pH 5 ± 0.2 (P1). During the research, water quality were in tolerance range for hatching and rearing of eggs and larvae catfish that were temperature of 26.2 – 27.9 oC, dissolved oxygen of 4.7 – 5.5 mg.l-1, and ammonia of 0.22 – 0,47 mg.l-1.
