摘要：
The nutritional value of Artemia nauplii from the Great Salt Lake was effectively improved for larval striped bass (Morone saxatilis) by incorporation of unsaturated fatty acids (20:5n-3 and 22:6n3) into the nauplii by the direct method of enrichment, Survival at 24 days post-hatch increased from 23% to 64% when fish were fed nauplii containing 8.24% lipid as 20:5n-3 and 3. 10% as 22:6n-3 fatty acids. Growth of the larval fish was significantly improved by a diet of fatty acid enriched nauplii. Fatty acid composition of the larvae reflected the composition of the fed nauplii. Results suggested a requirement by larval striped bass for long-chain highly unsaturated fatty acids and an inability, at this stage of development, to elongate and desaturate the shorter chain fatty acids in sufficient amounts to meet this requirement.
