| 摘 要： | 2007年4月25～30日,对乌伦古湖河鲈的食性进行了调查研究.与1987年比较乌伦古湖河鲈食物组成发生了明显的变化;主要食物由20年前的摇蚊幼虫变为易得的池沼公鱼,适口饵料生物的减少使得河鲈选择了替代食物.推断了乌伦古湖河鲈食物的制约是影响种群补充的重要原因. |
| 关 键 词： | 乌伦古湖 河鲈 池沼公鱼 食物竞争 |

| Abstract: | Diet Composition of Perch(Perca fluviatilis Linnaeus) in Ulungur Lake was studied in 25~30th Apri.2007.Great variation was found in last two decades that fish instead of tendipes worm became the most important prey group of perch.Lack of preferable food resulted in perch living on replacement food of pond smelt(Hypomesus olidus Pallas).So the conclusion was reached that food is the important bottle neck of the perch population development in Ulungur Lake. |
| Keywords: | Ulungur Lake Perch(Perca fluviatilis Linnaeus) Pond smelt(Hypomesus olidus Pallas) Biological invasion Food competition |
