摘要
2016—2018年利用流刺网、定置刺网、撒网、地笼、罾网及饵钩等渔具对天津市蓟县城东4 km蓟运河左支流州河上游出山口处的于桥水库(北纬40°20',东经117°25')的鱼类进行了多次采集调查。共采集到鱼类24种,隶属于5目10科24属,其中鲤形目15种,鲇形目2种,鲈形目4种,鲑形目2种,合鳃目1种。与历史资料相比,于桥水库新增鱼类6种,其中鲤形目2种,鲈形目1种,鲑形目2种,合鳃目1种;消失10种,其中鲤形目9种,刺鱼目1种。根据生物操纵理论,提出保护水库生态平衡的建议。
Composition and Diversity of Fishes were investigated in samples collected by fishing gears including drifting gill nets,fixed gill nets,cast nets,traps,and bait hooks in Yuqiao Reservoir(latitude 40°20'north,longitude 117°25 east)at the mouth of the upper reaches of Liuzhou River,the left tributary of Ji Canal,4 km east of Jixian City,Tianjin from 2016 to 2018.The results showed that there were 24 species fish were found in Yuqiao Reservoir,belonging to 5 orders,10 families and 24 genera,15 species in Cypriniformes,2 species in Siluriformes,4 species in Perciformes,2 species in Salmoniformes,and 1 species in Synbranchiformes.Compared with the previous data,6 species was shown to be increased,including 2 species in Cypriniformes,1 species in Perciformes,2 species in Salmoniformes,and 1 species in Synbranchiformes;and 10 species were not observed,including 9 species in Cypriniformes,and 1 species in Gasterosteiformes.The suggestion is proposed for protection of the ecological balance in Yuqiao Reservoir by theory of biomanipulation.
