摘要: Abstract Dietary lipids and fatty acids composition play an important role in the reproductive processes, embryo development larval survival marine fish. Long-chain polyunsaturated (LC-PUFA) are especially for egg quality. The main objective of present study was to evaluate effects increasing dietary n-3 LC-PUFA levels on spawning performance quality greater amberjack (Seriola dumerili). Sixteen mature broodfish were distributed four 40 m3 circular tanks fed diets containing different LC-PUFA: diet D1 with 1% dry weight basis (dw), D2 1.7% dw, D3 2.3% dw D4 3% dw. fecundity significantly higher (P
