HANGZHOU, Oct. 4 (Xinhua) -- Chinese researchers have discovered a new species of fish加拿大pc28预测在线, Opsariichthys iridescens, in east China, which features beautiful colors.
The research findings describe how the species is distinguished from congeners by morphological features, which have been validated through gene-based phylogenetic analysis.
次节，于米提连续2球接球三分命中，道格拉斯反击上篮命中后球队扳平比分！第二节过半，在全场的加油声中球队气势十足，两队分差始终在5分左右。第二节最后时刻，沃伦抛投打进，两队2分分差进入更衣室。
卫冕冠军辽宁队，在经历之前的连败加拿大pc28预测在线，最近两场比赛连胜福建和广州，1分险胜广州队以后，辽宁队的战绩提升到15胜7负，从积分榜第8的位置，直接杀回积分榜第5。而在辽宁队后边的山东队，他们的战绩也是15胜7负，排在积分榜第6。北京队少赛一场，战绩是15胜6负，屈居积分榜第7名。第八名则属于青岛队，他们的战绩是14胜8负。
The discovery was published in a recent edition of the international academic journal Zookeys. The research was led by Yang Jinquan, a professor at Shanghai Ocean University, in collaboration with the Zhejiang Forest Resource Monitoring Center and other institutions.
The new species can be distinguished from its closely related species with a genetic divergence of over 14 percent, according to the research findings. The new species is found in the Qiantang and Oujiang River systems in Zhejiang Province and the tributaries of the lower Yangtze River adjacent to the Qiantang River.
Yang said that the discovery of several new species living in fast-flowing rivers or streams including Opsariichthys iridescens, indicates that the diversity of freshwater fish species in the region is still underestimated.
According to Yang, these stream fish species are food resources for waterfowl and other animal, contributing to the nutrient cycling and water purification of rivers.
Yang said protecting these fish species is essential to maintaining the balance of aquatic ecosystems加拿大pc28预测在线, which helps to maintain biodiversity and promote the sustainable development of ecotourism and fisheries. ■
