【摘要】 对相同饲养条件下经产虹鳟和初产金鳟亲鱼自然成熟产卵群体生物学特性及其成熟鱼卵中四种不饱和脂肪酸 (亚油酸、亚麻酸、EPA、DHA)组成含量进行分析比较。结果表明 :两种鱼成熟产卵期和成熟卵粒重相近 ;成熟鱼卵四种脂肪酸组成含量 (mg/ g鲜样 )均依次为亚油酸 >DHA >EPA >亚麻酸 ,相关明显 (R≈ 0 97) ;虹鳟鱼卵四种脂肪酸总和 ( 6 68) ,必需脂肪酸 ( 3 831) ,DHA( 2 534 )含量明显高于金鳟( 3 93、2 2 1、1 14)。金鳟受精卵发眼率较低 ,可能与鱼卵EFA ,DHA含量低有关更多还原

【Abstract】 The biology characteristic of female mature fish Salmo gairdneri Richardson、Oncorhynchus mykiss and content of four polyunsaturated fatty acid (PUFA) in its spawn were analysed and studied.The result showed that autumn、brood amount and spawn weight of the two female mature fish was about colse;Four fatty acid valae(mg/g fresh) were linoleic acid>DHA>EPA>linolenic acid,content of two trout-bulltrout spawn had good linera correlation (R≈0 97)。 Total PFA of four polyunsaturated fatty acid、EFA、linolenic、linoleic acid、DHA content and eyed egg valae of ist spawn of the rainbow trout were significantly high compare with Oncorhynchus mykiss.更多还原
