ANALISIS KEBERHASILAN PEMIJAHAN IKAN TAWES (Barbonymus gonionotus) MELALUI APLIKASI HORMON OVAPRIM DI UPR CENRANA MAS INDAH

Abstract

This study aimed to analyze the success rate of spawning in tawes fish (Barbonymus gonionotus) through the application of the Ovaprim hormone at a single dose of 0.5 ml/kg of female broodstock. The research was conducted at a Community-Based Hatchery Unit (UPR) using spawning media in the form of plastic basins as simple containers. Male and female broodstock with mature gonads were selected and injected with Ovaprim hormone, then allowed to spawn under controlled conditions. The results showed that the total number of eggs produced reached 656,000, with a hatching rate of 83.52%. The hatched larvae were subsequently reared, and on the third day, a survival rate of 91.25% was recorded. These results indicate that the use of Ovaprim is effective in inducing spawning in tawes fish, and simple spawning media such as basins can be used efficiently, provided that water quality and sanitation management are properly maintained. This study recommends further testing with different hormone doses and regular monitoring of water quality to improve sustainable aquaculture efficiency.
