The performance analysis of hybrid seeds between catfish (Clarias gariepinus Burchell) semarang and sangkuriang strains

This study aimed to analyze the performance of hybrid seeds between catfish (Clarias gariepinus Burchell) semarang and sangkuriang strains by parameters of fecundity, length and weight gain and seeds survival rate. The material used in this study was the parent of catfish semarang and sangkuriang strains. The research method used was experimental method using Completely Randomized Design (RAL), consists of four treatments and three replications. Those were Treatment A (semarang/HH ♀ × semarang/HH ♂), Treatment B (semarang/HH ♀ × sangkuriang/SS ♂), Treatment C (sangkuriang/SS ♀ × sangkuriang/SS ♂) and Treatment D (sangkuriang/SS ♀ × sangkuriang/SS ♂). The results showed that fecundity of most catfish eggs were obtained from treatment A, B, C and D. The hatching rate of catfish eggs from various treatments was not significantly different. Performance of seeds with length and weight parameters showed that newly hatched larvae until the age of one-week-feeding catfish are not significantly, the difference in seed performance began to appear on the 14th day of feeding. The order of the best treatment result were C, B, D and A. The difference was more significant at 28 days of feeding.
