摘　　要：比较了野生与养殖褐牙鲆(Paralichthys olivaceus)亲鱼卵、肝脏及肌肉营养学成分及繁殖力,以分析其繁殖阶段的营养需求及繁殖力的差异.结果显示:野生未成熟、野生成熟、普通养殖与维生素A、C、E营养强化的卵中粗蛋白含量分别为69.95%、74.35%、54.69%和67.30%,粗脂肪含量分别为17.88%、16.32%、19.83%和17.11%,野生亲鱼卵中粗蛋白含量显著高于养殖亲鱼(P<0.05),粗脂肪含量差异不显著(P>0.05).野生未成熟亲鱼肝脏中粗蛋白含量显著高于野生成熟亲鱼和养殖亲鱼(P<0.05),粗脂肪含量显著低于野生成熟亲鱼和养殖亲鱼(P<0.05).野生亲鱼肌肉中粗脂肪含量显著低于养殖亲鱼(P<0.05).野生未成熟、野生成熟、普通养殖和营养强化亲鱼的绝对繁殖力分别为1.88×106、2.40×106、0.68×106和1.38×106(粒),相对繁殖力分别为422、703、349和538(粒/克净体重),野生亲鱼的繁殖力显著高于养殖亲鱼(P<0.05),营养强化显著提高了养殖亲鱼的繁殖力(P<0.05).In order to investigate the nutrient requirement of Japanese flounder（ Paralichthys olivaceus） broodstock,approximate composition of muscle,liver,eggs,absolute fecundity（ AF） and relative fecundity（ RF） of wild and cultured Japanese flounder broodstock are analyzed. Results show that the crude protein of eggs in immature wild fish,mature wild fish,commonly cultured fish and enriching cultured fish are 69. 95%,74. 35%,54. 69% and 67. 30%,respectively,while their crude fat are 17. 88%,16. 32%,19. 83% and 17. 11%,respectively. The crude protein of wild fish is significantly higher than that in cultured fish（ P〈0. 05）,while the crude fat among them is not different（ P〈0. 05）. The crude fat of muscle in wild fish is significantly lower than that in cultured fish（ P〈0. 05）. The crude protein of liver in immature wild fish is significantly higher than that in mature wild fish and cultured fish. However,the crude fat in immature wild fish is lower than that in mature wild fish and cultured fish（ P〈0. 05）. The absolute fecundity of wild immature fish,mature fish,commonly cultured fish and enriching cultured fish are 1. 88 × 10^6,2. 40 × 10^6,0. 68 × 10^6 and 1. 38 × 10^6eggs（ P〈0. 05）,respectively,and their relative fecundity are 422,703,349 and 538 eggs / g,respectively. The fecundity of wild fish is significantly higher than that in commonly cultured fish（ P〈0. 05）. The fecundity is significantly improved through nutrition enrichment（ P〈0. 05）.
