Effect of Feeding n-3 HUFA Enriched Artemia on the Growth and Fatty Acid Profile of Macrobrachium rosenbergii De man

A 30-day experiment was conducted to investigate the effects of enrichment on fatty acid composition of adult Artemia through lipid emulsions containing highly unsaturated fatty acids (HUFA) and its impact on growth, survival and fatty acid composition of sub-adult of giant fresh water prawn Macrobrachium rosernbergii. Enrichment was done in emulsions containing Mega3 capsules as sources of lipid. The prepared emulsions were found efficient in enriching adult Artemia by increasing level of eicosapentaenoic acid (EPA) and docosahexaenoicacid (DHA) up to maximum of 5.69 and 3.78%, respectively, in 2h enrichment. Maximum Specific Growth Rate (SGR) of subadult increased (4.951±0.29) with increased amount of EPA and DHA in dietary adult Artemia. It also revealed good effect in terms of fatty acid composition. The nutritional quality of adult Artemia in relation to fatty acids can be increased by enrichment which can influence the growth and fatty acid composition of sub-adults of freshwater prawn.
