The use of lipid emulsions for sterol supplementation of spat of the Pacific oyster, Crassostrea gigas
Abstract To determine the ingestion and absorption of lipid emulsions, spat were fed algae deficient in stigmasterol and cholesterol and an emulsion containing these two sterols. The ingestion-absorption of the emulsion was estimated by measuring incorporation of these two sterols in oyster lipids d...
