The effect of various doses vitamin B complex on the spesific weight growth rate of seabass (Lates calcarifer) larvae

Abstract

Seabass (Lates calcarifer) is one of the fishery commodities with important economic value which in its growth requires vitamin B complex that helps as nutrient intake required by larvae for maximum growth. This study aimed to determine the best dose of vitamin B complex on the growth rate of specific weight of white snapper larvae. This research was conducted from October to November 2020 at the Brackish Water Cultivation Fisheries Center, Takalar Regency, South Sulawesi. The experimental animals used were white snapper larvae 4-5 days old. The number of white snapper larvae used in this study was 15,000 larvae with 1,250 for each research container. The study was designed using a completely randomized design (CRD) consisting of 4 treatments with 3 replications, namely 0, 75, 150, and 225 mg/L doses of vitamin B complex. The results showed that the administration of vitamin B complex had a significant effect on the growth rate of the specific weight of white snapper larvae. The growth of specific weight of white snapper larvae was highest at a dose of 75 mg/L, which was 21.81%/day, while the lowest was at 0 mg/L, which was 18.94%/day.
