Enrichment Moina sp. with fish meal improved growth performance of Colossoma macropomum larvae

Abstract

Colossoma macropomum is freshwater fish which has a great demand in Indonesia. However, cultivation of C. macropomum is still developing. C. macropomum cultivation requires a good quality seeds to support the success of aquaculture. The exhausted egg yolks of C. macopomum larvae require appropriate and high-nutrient feed intake through enrichment of feed with the addition of natural feed nutrients (Moina sp.). This study aimed to evaluate the effect of additional Moina sp. enriched with fish meal on the survival and growth of C. macropomum. This study was structured using a completely randomized design (CRD) consisting of 4 treatments with 3 replications, namely: treatment A (Moina sp. without enriched with fish meal), treatment B (Moina sp. enriched with fish meal 4 gr/L), treatment C (Moina sp. enriched with fish meal 6 gr/L), and treatment D (Moina sp. enriched with 8 gr/L fish meal). The results showed that the additional of Moina sp. enriched with fish meal had a significant effect on the absolute length growth, absolute weight growth, and specific growth rate but had no significant effect on survival of C. macropomum. The highest value was obtained in treatment C (Moina sp. enriched with fish meal 6 gr/L) with the absolute length growth of 0.46 cm, absolute weight growth of 0.010 gr, and specific growth rate of 3.184%/day.
