Effect of Feeding Daphnia sp. Enriched with EM4 Against the Seed Growth of Striped Catfish (Pangasianodon hypophthalmus)

Aquaculture

Catfish is one of the leading freshwater fish commodities and has the potential to be developed and continuously boosted in productivity. This research aimed to determine the optimal dose of EM4 on Daphnia sp. enrichment as a natural food striped catfish (Pangasianodon hypophthalmus) towards survival and growth. The study was conducted from November 2021 – January 2022 at the Fisheries Laboratory, Faculty of Fisheries and Marine Sciences, Padjadjaran University. Researchers chose it by using experimental with a completely randomized design. It consisted of 4 treatments and three replicates. A treatment (control), B (10mL/L), C (20 mL/L) and D (30 mL/L). The fish used in this study were 240 striped catfish aged 15 days with a length of 2.5±0.55 cm obtained from fish seed sellers in Bekasi. Analysis of growth data used the normality test and then analyzed the data for variance (ANOVA) with a 95% confidence level, while data analyzed water quality descriptively. The results showed that feeding Daphnia sp. enriched with EM4 at a concentration of 10mL/L resulted in a length growth of 2.96%, specific growth rate of 7.40%, and feeding efficiency value of 34.35%, and survival rate of 88.33% on striped catfish seeds.
