Abstract
Marine fish larvae have a requirement for large quantities of n − 3 highly unsaturated fatty acids (HUFA), particularly docosahexaenoic acid (DHA; 22:6n − 3), and dietary deficiencies of these induce a range of pathologies in fish including behavioural abnormalities. Therefore, there is a growing demand for natural lipids highly enriched in DHA as nutritional supplements during larval development. In the present study, DHA-rich products were obtained from fish neural tissues by a procedure involving ensiling in organic acids followed by neutralisation, drying, milling and sieving to produce the final paniculate, crumbed products. Lipid content varied in the neural tissue silages from 5.5% to 46.5% but all lipid contained high percentages of DHA and high DHA:EPA (eicosapentaenoic acid; 20:5n − 3) ratios ranging from 3.5 to 5.4. Tuna eye silage was a high lipid, high triacylglycerol (90.6% of total lipid) product and was particularly effective in increasing DHA content, outperforming a commercial product, in rotifer (Brachionus plicatilis) enrichment. Cod brain/eye silage had an intermediate content (18.2%) of lipid, which contained almost 50% as phospholipid, and proved as effective as a commercial enricher in increasing DHA content in Artemia nauplii. Moreover, Artemia nauplii, enriched with the cod brain/eye silage were more effective than nauplii enriched with a commercial enricher in increasing the DHA content of larval turbot brain. In conclusion, tuna eye and cod brain/eye silages are useful as enrichers of Artemia nauplii and rotifers for feeding marine fish larvae prior to weaning onto pelleted formulated diets.

Cod brain/eye silage had an intermediate content (18.2%) of lipid, which contained almost 50% as phospholipid, and proved as effective as a commercial enricher in increasing DHA content in Artemia nauplii. Moreover, Artemia nauplii, enriched with the cod brain/eye silage were more effective than nauplii enriched with a commercial enricher in increasing the DHA content of larval turbot brain. In conclusion, tuna eye and cod brain/eye silages are useful as enrichers of Artemia nauplii and rotifers for feeding marine fish larvae prior to weaning onto pelleted formulated diets.</abstract><subject><genre>article-category</genre><topic>Nutrition</topic></subject><subject><genre>Keywords</genre><topic>Artemia</topic><topic>Rotifers</topic><topic>Docosahexaenoic acid</topic><topic>Lipids</topic><topic>Silage</topic><topic>Enrichment</topic></subject><relatedItem type="host"><titleInfo><title>Aquaculture</title></titleInfo><titleInfo type="abbreviated"><title>AQUA</title></titleInfo><genre type="journal">journal</genre><originInfo><dateIssued encoding="w3cdtf">19970115</dateIssued></originInfo><identifier type="ISSN">0044-8486</identifier><identifier type="PII">S0044-8486(00)X0040-3</identifier><part><date>19970115</date><detail type="volume"><number>148</number><caption>vol.</caption></detail><detail type="issue"><number>2–3</number><caption>no.</caption></detail><extent unit="issue pages"><start>77</start><end>264</end></extent><extent unit="pages"><start>213</start><end>231</end></extent></part></relatedItem><identifier type="istex">D3489C25DE01BAD2CCF9F24A72DA0E71B135153A</identifier><identifier type="DOI">10.1016/S0044-8486(96)01396-8</identifier><identifier type="PII">S0044-8486(96)01396-8</identifier><recordInfo><recordContentSource>ELSEVIER</recordContentSource></recordInfo></mods></metadata></istex></record>Pour manipuler ce document sous Unix (Dilib)
