摘要: Abstract The requirement for dietary ( n −3) PUFA growth, survival and swim bladder development in gilthead seabream, Sparus aurata , larvae was tested using rotifers with various levels of PUFA. Four rotifer treatments differing their content (0.8, 3.2, 5.1 8.4 mg/g dry body weight, DBW) were prepared by feeding them combinations oil emulsions dried squid (rich both EPA (20:5 DHA (22:6 −3)). A fifth treatment consisted enriched on the algae Nannochloropsis sp. Regression analyses, from emulsion treatments, performed relationships between larval phospholipid growth. equations describing these correlations then used to examine whether same parameters fed -enriched a result they consumed or some other nutritional factor. results indicate that significantly P (8.4 showed four-fold increase growth (1263% vs. 312%) over offered lowest (0.8 DBW). In contrast, there no compelling evidence and/or strongly associated implies that, despite sources nutrition algal media, this fatty acid determines value larvae.
