嵩县鱼类资源调查

Current status of fishery resources in Songxian country

2016年5月16日-5月22日,河南省鱼类资源调查队对河南省洛阳市嵩县主要河流展开了调查工作。本次调查共设采样点32个,主要涉及黄河水系、长江水系和淮河水系,捕获标本37种,隶属于4目6科30属。鲤形目鱼类种类占采集样本总种类的主要组成部分,占总种数的81.08%;其次是鮎形目,占比为8.10%;最少的是餅形目和鮭形目,均仅有两种,占比均为5.41%。调查结果显示:嵩县鱼类种类较少,冷水鱼类数量较多,造成这一现象的原因可能与嵩县地质环境有关。地势条件复杂多样,气候多变。鱼类在摄食、繁殖及栖息习性等方面呈现多样化特征。根据鱼类区系复合体学说,嵩县鱼类资源主要为江河平原区系复合体种类。

From May 16 to May 22,2016,the Henan Provincial Fish Resources Survey Team conducted an investigation into the main rivers in Song County,Luoyang City,Henan Province.A total of 32 sampling points were set up in this survey,mainly involving the Yellow River system,the Yangtze River system and the Huaihe River system.37 specimens were captured,belonging to 4 orders,6 families and 30 genera.The species of the scorpionfish accounted for 81.28%of the total species,and the second was the scorpion,accounting for 8.10%;the least was the scorpion and the scorpion,only Two,accounting for 5.41%.The survey results show that there are fewer fish species and more cold fish species in Songxian County,which may be related to the geological environment of Songxian County.The terrain conditions are complex and diverse,and the climate is changeable.Fish exhibit diverse characteristics in terms of feeding,reproduction and habitat habits.According to the theory of fish fauna complex,the fish resources of Songxian County are mainly the assemblages of the river plains.
