Abstract: A lasted two years experiment was carried out to detect the acclimatization of the Yangtze River Coilia ectenes in cage culture for the Coilia ectenes resource protection from 2011 to 2013. In this experiment，totally 35 203 Coilia ectenes fingerlings were transported from the Yangtze River in Nantong ( Jiangsu Province) to Qiandao Lake in Hangzhou (Zhejiang Province) by trucks respectively in September oi 2011 and 2012 . After two years of acclimatization，totally 17 000 Coilia ectenes was survived (7 500 of 2011 and 9 500 of 2012) ，the survival rate of fishes in 2011 was 35.30 % ，average body length was 28.8 cm and average body weight was 74.5 g ； the survival rate of fishes in 2012 was 68.10 % ，average body length was 20.9 cm and average body weight was 21.4 g. The results of this experiment demonstrated that Coilia ectenes could cultured in cage and the experience from transport， acclimatization， feeding and daily management of cage culture Coilia ectenes provided us more possibilities for the Coilia ectenes research in the future.
