A PROCESS TO PREPARE NATURALISED ARTEMIA FRANCESCIANA FROM INDIAN SUBCONTINENT WITH HIGH DOCOSAHEXAENOIC ACID AND TREHALOSE FOR AQUACULTURE APPLICATIONS

摘要

The present invention relates to a process of preparing an enriched live feed from Artemia nauplli for raising fish in salinied seawater. The process involves feeding the young freshly hatched Artemia nauplli on marine microalgae selected from the family prymnesiophytes or eustigmatophytes in autoclaved salinied seawater as aquaculture rearing medium. The enriched Artemia nauplli was found to posses higher level of osmoregulator saccharide trehalose, polyunsaturated fatty acid, carotenoid content, protein content and the trehalose content than the freshly hatched Artemia nauplli. The saturated fatty acid (SFA) content, the monosaturated fatty acid (MUFA) content and the lipid content of Artemia nauplli after enrichment is lower than lipid content of the Artemia nauplli before enrichment. The Carotenoid content, the protein content and the trehalose content of Artemia nauplli after enrichment is based on the salinity level of the autoclaved seawater contained in the Artemia nauplli culture tank and/or the duration of enrichment.
