加拿大pc28官网技巧 New fish species found in east China

HANGZHOU加拿大pc28官网技巧, Oct. 4 (Xinhua) -- Chinese researchers have discovered a new species of fish, 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.

在踝关节手术中，前入路踝关节镜微创手术这种手术方式相较于传统的足踝开放式手术，具有显著的优势加拿大pc28官网技巧，踝关节镜手术通过微小的切口插入镜头和手术器械，对踝关节内部进行细致的观察和治疗，为了完美配合踝关节镜的使用，踝关节无创牵引系统专为配合踝关节镜使用。

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官网技巧, which helps to maintain biodiversity and promote the sustainable development of ecotourism and fisheries.  ■
