What is Delivery of dietary components to larval shrimp (Penaeus vannamei) by means of complex microcapsules about?

Efficient delivery of nutrients is necessary for the successful study of aquatic larval nutrition. Conventional artificial food particles for larval shrimp (Penaeus vannamei) have poor water stability and poor nutrient retention or both. We developed a novel food particle type that retained low-molecular weight, water-soluble nutrients (vitamins and glucose) within lipid-wall microcapsules embedded with dietary ingredients in particles of gelled alginate-gelatin. The combination of lipid-wall microcapsules (LWMs) embedded in gelled food particles was termed complex microcapsules (CXMs). Eighty-five percent of 14C-activity associated with encapsulated 14Cglucose was retained by CXMs (after 18 h of suspension in seawater). Bioavailability of CXM-encapsulated molecules was demonstrated by release of encapsulated dye marker into the gut lumen of larval shrimp, and by uptake of 14C from encapsulated 14C-glucose. Minimum ingestion rates, calculated from 14C-uptake for larval shrimp (Mysis-I through Postlarva-2) fed CXMs, ranged from 48 to 99 lag dry wt larva 1 d-1, and were similar to literature values reported for ingestion of live rotifers by penaeid larvae.
