Abstract

The Banggai cardinal fish has quite high commercial value as an ornamental fish. There are around 700,000‒900,000 traded cardinal fish per year. The Banggai cardinal hatchery currently needs to be developed. Efforts are being made, namely the development of the production of Banggai cardinal fish seeds by using technology that is easy to apply. The purpose of this study was to gather information on the techniques for seeding cardinal Banggai to produce quality seeds. The Banggai cardinal fish is a type of fish that incubates eggs in its mouth or is called a mouth breeder. The total number of eggs incubated by the mother is 1.520 eggs. The number of eggs that came out of the mother's mouth was 1.115 so the hatching rate (HR) obtained was 76%. The seed survival rate at the end of the observation was 95% with a total revenue of IDR 95.040.000 and a profit of IDR 19.795500.

Abstract

Nilem fish Osteochilus vittatus is an economically valuable freshwater species that also supports ecological sustainability. However, its aquaculture is hindered by slow larval growth and high mortality rates. This study aimed to evaluate the effectiveness of vitamin C-enriched daphnia as a dietary supplement to enhance the growth performance and survival of nilem fish larvae. A Completely Randomized Design (CRD) was implemented, consisting of 4 treatments with 3 replicates each: VC0 (0 mg L-¹), VC200 (200 mg L-¹), VC250 (250 mg L-¹), and VC300 (300 mg L-¹) of vitamin C enrichment. Larvae aged 15 days were stocked at a density of 5 individuals L-1 in aquarium containing 7 L of water. Enrichment was conducted by immersing daphnia in vitamin C solutions for 3 hours prior to feeding. The results indicated that vitamin C supplementation significantly improved larval growth (p<0.05), with the highest length and weight gains observed in treatments VC300. However, survival rates peaked at 100% in VC200 and VC250 treatments. The study concludes that vitamin C-enriched daphnia, particularly at 200–250 mg L-¹, effectively enhances both growth and survival in nilem fish larvae
