| 摘 要： | 为了解瓦氏雅罗鱼对盐碱水体的适应性,在吉林西部盐碱水体三王湖中移入瓦氏雅罗鱼(Leuciscus waleckii),通过对其生长、食性和生态位的研究,分析其对三王湖的适应情况,并与吉林东部老龙口水库的瓦氏雅罗鱼野生群体相比较.结果显示,两个水体中瓦氏雅罗鱼的生长均属于非等速生长类型中的正异速增长,肥满度指数没有显著性...

| Abstract: | In order to understand the adaptation of Leuciscus waleckii to the saline-alkaline water,L.waleckii was tranplanted into Lake Sanwang which is a saline-alkaline water in western Jilin Province.Based on the researches of the growth,feeding habits and ecological niche of L.waleckii,its adaptability to Lake Sanwang was analyzed by comparison with the wild population of L.waleckii in Laolongkou Reservoir in eastern Jilin Province.The results showed that,the growth of L.waleckii in both water bodies belonged to positive allometric growth within non-isometric growth type,and no significant difference were detected in plumpness index(P≥0.05).L.waleckii belonged to the medium trophic niche in Lake Sanwang,which was an omnivorous fish with animal food preferance.In Lake Sangwang the relative abundance of L.waleckii was negatively correlated with pH value,salinity,conductivity,total dissolved solids,total nitrogen,total phosphorus,non-ionic ammonia,chemical oxygen demand,five-day biochemical oxygen demand,alkalinity and phytoplankton density,whereas positively correlated with dissolved oxygen and zooplankton density.However,the correlations were not significant(P≥0.05).The results indicated that L.waleckii adapted well to saline-alkaline water in western Jilin Province,and showed high tolerance to the water environment,thus it can quickly form a dominant population under the condition of appropriate fish fauna composition. |
