摘要
[目的]协调丹江口水库渔业与水质保护的关系。[方法]对该水库的渔具类型及相应的渔获物结构进行了调查。[结果]共采集到鱼类25种,隶属4目6科,其中鲤形目种类最多,共18种。鲢、蒙古!、鳙、翘嘴!、鲤、鲫、、鲇在生物量中的比例较高,分别为29.80%、20.18%、13.62%、10.09%、5.15%、4.65%、3.77%和3.45%;和蒙古!在样本总数量中占绝对优势,分别占41.65%和32.55%。[结论]目前丹江口水库鱼类群落结构空间差异较小,但广适性和静水性鱼类成为了优势种,这与生境的剧烈变化有关。
[Objective] To coordinate the relationship between water quality protection and fisheries in the Danjiangkou Reservoir. [Method] The types of fishing gears and structure of fishes in catch were investigated. [Result] A total of 25 fish species were collected, belonging to 4 orders and 6 families. The order Cypriniformes with 18 species was the most dominant group. The biomass proportion of Hypophthalmichthys molitrix, Culter mongolicus, Aristichthys nobilis, C. alburnus, Cyprinus carpio, Carassius auratus, Hemiculter leucisculus , and Silurus meridionalis were higher, accounting for 29.80%, 20.18%, 13.62%, 10.09%, 5.15%, 4.65%, 3.77% and 3.45%, respectively. H. leucisculus and C. mongolicus were the most dominant species in total number of samples, accounting for 41.65% and 32.55%, respectively. [Conclusion] The community structure of fisheries in the Danjiangkou Reservoir had small spatial differences, eurytopic and lentic fish species were dominant species, which was related with the acute changes of habitat.
