摘要

摘要: 本文研究了厦门港瘦尾胸刺水蚤(Centropages tenuiremis Thompson et Scott)成体的体长、体重以及摄食率.结果表明,瘦尾胸刺水蚤的体长和体重具有显着的季节变化:冬、春季的个体比夏初、秋末的大,个体大小与海区水温呈显着负相关.摄食率的季节变化亦比较明显,且雌性成体的摄食率大于雄性成体的摄食率.单位体重的摄食率[Ic',μg/(μg·d)]与水温(t,℃)有显着的回归关系(♀:Ic'=0.056t-0.249,r=0.710;♂:Ic'=0.034t-0.315,r=0.798).

Abstract: The body length and weight and ingestion rate of adult Centropages tenuiremis Thompson and Scott in Xiamen Harbor were studied.The results showed that the body length and weight have significant seasonal variations,they are bigger in winter and spring than that in earlier summer and later autumn.There is negative correlation between the body size and field sea water temperature.The seasonal variation in ingestion rate is relatively significant.Ingestion rate of adult female is larger than that of adult male.Water temperature effects notably on weight specific ingestion rate (♀:Ic'=0.056t-0.249,r=0.710;♂:Ic'=0.034t-0.315,r=0.798).
