| 摘 要： | 测定了海捕银鲳亲鱼肌肉，肝脏和性腺组织的氨基酸，并分析了不同性腺发育阶段的氨基酸变化。结果表明，雄性V期亲鱼精巢中的牛磺酸含量最高（27.8mg/g），显著高于肌肉和肝脏组织，而雄性V期亲鱼氨基酸总量在肌肉中最高（631.4 mg/g），其次是精巢（544.8 mg/g）和肝脏（468.0 mg/g）组织。雌性亲鱼肝脏中的牛磺酸含量（13.7 mg/g）显著高于卵巢和肌肉组织。在卵巢从III期发育到V期过程中，雌性亲鱼肌肉和肝脏中的氨基酸总量在V期下降显著，而卵巢氨基酸总量维持稳定。在总氨基酸的组成上，肌肉中含量高的氨基酸为Glu，Lys， Asp，Leu和Arg；肝脏中含量高的为Glu，Lys， Asp，Val和Leu；精巢中含量高为Glu，Asp， Lys， Arg和Val；卵巢含量高中为Glu，Lys，Leu，Val和Asp。性别和性腺发育阶段对亲鱼肌肉总氨基酸组成无影响。游离氨基酸含量在III 、IV和 V期卵巢中的含量分别为17.7 mg/g ，41.5 mg/g和29.6 mg/g，且其组成随性腺发育阶段的不同而有显著差异。 |

| Abstract: | The amino acids of the muscle, liver and gonad tissues of the wild-caught silver pomfret (Pampus argenteus) broodstocks from Zhoushan fishery in the East China Sea were investigated. The changes of content and composition on amino acid in different tissues as the gonad development were also analyzed. The results indicated that the spermary in V stage of the male broodstock had the highest taurine content, 27.8mg/g, which was significant higher than that in muscle or in liver of the broodstocks respectively. The total amino acids of muscle, spermary and liver of the V stage of the male broodstocks were 631.4 mg/g, 544.8 mg/g and 468.0 mg/g respectively. While in female broodstocks, the taurine content (13.7 mg/g) in liver tissue was significant higher than those in ovary and muscle tissues. The total amino acid contents of muscle and liver of the broodstocks in V stage were declined significantly as the ovary developed from III stage to V stage. While the total amino acid content of ovary was stable during the ovary development from III stage to V stage. Glu, Lys, Asp, Leu and Arg were dominant in total amino acid composition of the muscle, while Glu, Lys, Asp, Val and Leu, Glu, Asp, Lys, Arg and Val, Glu, Lys, Leu, Val and Asp were dominant in total amino acid compositions of liver, spermary and ovary respectively. There were no effects of gender and ovary development stages on the total amino acid composition of the muscle. The free amino acid contents of ovaries in III, IV and V stages were 17.7 mg/g, 41.5 mg/g and 29.6 mg/g respectively. The compositions on free amino acid in ovaries were significant variable during the development from III stage to V stage. |
