Abstract
Rotifers and artemia are live food that are widely used in fish and crustacean hatchery activities. The results showed that the omega-3 fatty acid content of rotifers and artemia, especially EPA and DHA were low, even though EPA and DHA were very important in supporting the survival rate and growth of marine organism larvae. The purpose of this study was to analyze the effect of enrichment of moringa leaf powder on levels of omega-3 fatty acids (EPA and DHA) in rotifers and artemia. The enrichment container uses a 12 L volume bucket filled with 25 ppt of saline water. Enrichment method by soaking for 6 hours in rotifers with a density of 500.000 individuals/L and artemia nauplius with a density of 300.000 individuals/L. The study was designed using a completely randomized design consisting of 4 doses of Moringa leaf powder, namely: 0, 50, 100 and 150 ppm with 3 replications. The results showed that enrichment of rotifers and artemia nauplius with moringa leaf powder had a very significant effect (P<0.01) on the EPA and DHA content of rotifers and artemia (P<0.01). The highest content of EPA and DHA in rotifers and artemia at a dose of 150 ppm, namely EPA 0.93 g/100g and DHA 6.41 g/100g in rotifers, and EPA 0.09gr/100gr and DHA 0.07g/100g in artemia, while the lowest dose at 0 ppm was EPA 0.71g/100g and DHA 2.72g/100g in rotifers and EPA 0.03g/100g and DHA0.01 g/100g in artemia.
