近太湖新银鱼——银鱼移植新对象

NEOSALANX PSEUDOTAIHUENSIS -A NEW TRANSPLANT OBJECT OF ICEFISH

近太湖新银鱼不仅在形态上与太湖新银鱼很相似,而且它们的个体大小、生长速度、食性等方面也十分相近。近几年在湖北地区的湖泊、水库相继发现了近太湖新银鱼,并在湖北省广水市徐家河水库成为优势种类,形成了较大生产规模。从目前研究的结果来看,近太湖新银鱼也是适宜我国湖泊、水库移植的银鱼种类。

Icefishes (Salangidae) are very important and valuable fishes in the inland waters of China. The N. taihuensis was successfully introduced from Taihu Lake to Dianchi Lake by the scientific workers in Nanjing Institute of Geography & Limnology, CAS in the end of 1970s. Up to mow, there are only two species for successful transplantation, one is N. taihuensis, the other Protosalanx chinensis, although more than 20 species of icefish have been found and identified in China. Neosalanx pseudotaihuensis is a new species which was nominated by Zhang Yulin in 1987. It is similar to N. taihuensis not only in form, but also in body size, growth speed and food selestissty. In recent years, it has found its distribution in some lakes and reservoirs in Hubei Province, and becomes dominant and forms a larger productive scale in Xujiahe Reservoir, Guangshui City, Hubei Province. The research reveals that N. pseudataihuensis is a new icefish species which can be transplanted to lakes and reservoirs.
