EFEKTIFITAS OVAPRIM TERHADAP LAMA WAKTU PEMIJAHAN, DAYA TETAS TELUR DAN SINTASAN LARVA IKAN LELE DUMBO, CLARIAS GARIEPINUS
Abstract: This study aimed to
determine the effect of different doses of ovaprim on spawning time, egg
hatchability, and survival of African
catfish larvae (Clarias gariepinus). The research was done in the Central Local
Fish Seed (BBI) Jayapura, Papua Province. Experimental design used was
Randomized Complete Design. The study consisted of four treatments namely 0 ml,
0.3 ml, 0.6 ml and 0.9 ml ovaprim, each with three replications. Data collected
were spawning time, egg hatchability, and survival rate of African catfish
larvae. The number of containers used was as much as 12 buckets (for spawning,
hatching, and observation of survival rate of larvae). The results showed that
treatment with different doses of ovaprim hormones provided a significant
influence on the latency time of spawning, egg hatchability and survival rate
of larval. The dose of 0.3 ml ovaprim caould increase the latency time of
spawning, egg hatchability and survival rate of African catfish larvae. The
average latency time of hatching was 552 minutes, spawning and
egg hatchability 84.16% and survival rate of living larvae was 85.76%.
