INDUCED BREEDING AND SEED PRODUCTION OF NALEH FISH Barbonymus sp. USING SYNTHETIC HORMONES

The Naleh fish, Barbonymus sp., is a native freshwater fish in Aceh province, Indonesia, and considered one of the popular fish species for food and ornamental purposes. Induced breeding technology is crucial for the success for any fish farming practices, but currently, the effective hormone treatment and the induced breeding and seed production methods for Naleh fish is unknown. Therefore, the present study aims to determine the suitable hormone for effective induced breeding of Naleh fish. The study was conducted in January 2025 in Community Fish Breeding Center of Meunasah Krueng Village, Nagan Raya District, Aceh Province, Indonesia. The Completely Randomized Design method with 3 treatments and 5 replications for each hormone was tested. Three types of commercial available hormones, namely Ovaprim, Ovaspec, and HCG, were evaluated. The results show that the types of hormones tested significantly affected latency time, fertilization rate, and survival rate (p<0.05) but did not significantly affect hatching rate and larval malformation rate (p>0.05). The highest reproductive parameters performance were found in the Ovaprim induced fish groups. Therefore, it was concluded that Ovaprim hormone is the suitable hormone for the effective induction spawning and seed production of Naleh fish.
