Abstract
The icefish Neosalanx pseudotaihuensis (Salangidae) is a small (to 70 mm TL ), transparent fish that occurs naturally in central and eastern China. It is commercially important in many lakes and reservoirs, and recently has be en introduced into other waters. However, very little is known about its bi ology including growth. In this paper we studied the population structure a nd the growth of the icefish in Xujiahe Reservoir (central China) from May 1995 to December 1997. The icefish completed its life cycle within about on e year and the population consisted of one cohort. The main growth period w as May to December and little growth occurred at other times. Remarkable se asonal and interannual variations in the growth rates were found and these are discussed in relation to food availability, water temperature and fishi ng activity.
