Correspondence_Enrichment Effectiveness of Daphnia sp. With Viterna, Spirulina and Glutamine as Natural Food Preparation for Climbing Perch Larvae (Anabas testudineus Bloch)

Abstract

The aim of this research was to analyze the effectiveness of giving natural Daphnia sp feed enriched with viterna, spirulina and glutamine on the survival and growth of Climbing perch larvae. Proximate analysis was carried out at the end of the research to see the nutritional content of the enriched Daphnia sp. Sampling was carried out at the beginning and end of the research with a maintenance period of 30 days. This research used completely randomized design for 4 treatments and 3 repetitions, namely: treatment A (control), B (viterna enrichment 10 ml/L), C (spirulina enrichment 3 g/L) and D (glutamine enrichment 25 mg/L). The proximate test results showed that treatment B produced the highest protein content, namely 59.61%, while the control treatment was 49.45%. Survival rate ranges between 72-84%. Relative weight growth ranged between 196.78-506.88% while relative length ranged between 29.24-88.51%. The 10 ml/L spirulina enrichment treatment resulted in the highest relative growth in weight and length, while the highest survival rate was found in the 3 g/L spirulina enrichment treatment.
