| 摘 要： | 2017年3月19日,在长江口近海采集到1 ind中华鲟(Acipenser sinensis),全长133.0 cm、体质量13.8 kg,对其食物组成进行了分析。食性分析结果显示,春季中华鲟在长江口近海摄食较好,摄食强度为4级,饵料生物共有6种,其中鱼类有黄鲫(Setipinna taty)、焦氏舌鳎(Cynoglossus joyneri)和龙头鱼(Harpadon nehereus)3种,甲壳类有中华管鞭虾(Solenocera crassicornis)和口虾蛄(Oratosquilla oratoria)2种,头足类仅四盘耳乌贼(Euprymna morsei)1种。结合历史资料分析认为,中下层和底层鱼类是近海中华鲟最主要的饵料生物。

| Abstract: | One Chinese sturgeon (Acipenser sinensis) was collected in the coastal waters of the Yangtze Estuary on the 19th of March, 2017, and its food composition was analyzed.The results showed that A.sinensis fed very well in the coastal waters of the Yangtze Estuary in spring, and its feeding intensity was at level four.There were six diet species in the fish stomach.Among them, there were three fish species (i.e.Setipinna taty, Cynoglossus joyneri, and Harpadon nehereus), two crustacean species (i.e.Solenocera crassicornis and Oratosquilla oratoria) , and one cephalopod species (Euprymna morsei).The middle-and bottom-living fishes were the dominant prey species of Chinese sturgeon in the coastal waters based on the present and previous studies. |
