To study the growth characters of silver carp (Hypophthalmichthys molitrix) in Wudalianchi Lake, 248 individuals were sampled from August to October in 2013 and 2014 respectively. Age was determined through the scale annuli, and body length and body weight were backcalculated. Keys formula and Von Bertalanffy growth equation were fitted to analyze the growth of body length and body weight. Growth parameters of silver carp were compared between different years and areas. Results showed the growth formula of silver carp in Wudalianchi Lake as follows:L_t=52.992［1-e^-0.301(t_i-0.064)］,W_t=2621.649［1-e^-0.301(t_i-0.064)］^2.901. Growth rate curve of body length has no inflexion, i.e. growth rate of body length declined as age increased. Growth rate curve of body weight has an inflexion, and the age, body length and body weight corresponding to the inflexion were 3.602, 34.72 cm and 769.08 g, respectively. Compared with silver carp populations in other waters, the population in Wudalianchi Lake grew most slowly. The growth of silver carp in 2013-2014 was larger than in 2012-2013. The growth of silver carp might be affected by both biotic and abiotic factors such as genetic factors, water temperature, food organism density and pressure from intra and interspecific competition in Wudalianchi Lake.
