The wild juvenile fat minnow Phoxinus lagowskii Dybowski was collected from rivers or reservoirs ,and cultured in net cages or in ponds until they became broodstocks .A total of 670 pairs of broodstocks were induced to spawn by hormone injection (LHRH-A2 + DOM + HCG) ,with spawning success of 77 .8% ,fertilization rate of 84 .6% and hatching rate of 64 .0% ,and 1170 ,000 fertilized eggs and 558 ,000 fry were obtained in 2012 .In the study ,the techniques of artificial propagation of the fat minnow were studied including sexual distinguish in morphology , identification of maturity degree , spaw ning temperature and time ,hormone injection ,artificial insemination and hatching .
