摘要
分析了闽南-台湾浅滩渔场蓝图鲹、金色小沙丁鱼、鲐鱼、颌圆鲹 、竹筴鱼、羽鳃鲐等6种鱼类的生殖生物学特性。结果表明:肝指数、脂肪系数、丰满度的周年变化均与生殖过程有一定关系。成熟系数及性腺组织学观察得出6种鱼的生殖期分别为:蓝圆鲹 :3~7月;金色小沙丁鱼:3~7月;鲐鱼:1~5月:颌圆鲹4~7月;竹筴鱼:12月至翌年4月;羽鳃鲐:3~8月。
Seasonal variations in the hepatosomatic index, coefficient of fat and fullness are presented for six pelagic fishes (Decapterus maruadsi, Sardinella aurita,Pneumatophorus japonicus, Decapterus lajang, Trachurus japonicus, Rastrelliger kanagurta), which might be related with their reproductive activities. GSI variations and observation of gonadal microscopic sections show that the reproduction seasons for the six pelagic fishes are : D.maruadsi: March-July, S.aurita: March-July; P.japonicus: January-May, D.lajang: April-July; T.japonicus: December-April(nextyear): R .kanagurta: March-August.
