Abstract: The growth characteristics of Pseudorasbora parva cultured artificially were analyzed, in order to provide scientific basis for promoting culture of P. parva. P. parva were cultured artificially in the outdoor flowing water ponds from March 2016 to November 2016. The body weight, body length and total length were measured, respectively. Then the growth characteristics of P. parva were analyzed. The 180 days old fish had average total length of 3.96 cm, average body length of 3.23 cm and average body weight of 0.49 g. The special growth rate, daily weight gain and condition factor were affected by the change of water temperature significantly. The linear relation model between body length（LB）and total length（LT）was described as LT=1.0589LB 0.767,（R2=0.8628）, and the curve relation model between body length（LB） and body weight （W）of the P. parva was expressed as W=0.0466LB2.1623（R2=0.8306）. The coefficient variation was changed from 6% to 14% in body length, from 20% to 41% in body weight and changed from 1.45 to 5.31 in condition factor. P. parva shows strong adaptability under artificial culture condition, thus it indicated that P. parva should be cultured artificially on a large scale.
