In the present study，intergeneric hybridization between Hucho taimen （♀） and Brachymystax lenok （♂）were carried out by hormone induction and artifical propagation. The embryonic，larval and juvenile development of the hybrid were also studied preliminarily. The results showed that the total effective accumulated temperature of the embryonic development of the hybrid between Hucho taimen （♀） and Brachymystax lenok （♂） was 5 806.70℃·h at 6.2-8.9℃.The embryonic development were divided into 6 stages（prophase of cell division，cell division stage，blastula stage，gastrula stage，neurula stage and organ formation stage），24 periods. The hatching larvae could not swim，of which the bodies were diaphanous，and systemic circulation was clear. Seven days later，mouth cleft of yolk sac larva was clear，of which the top of head and belly began to be buff，and caudal fin differentiated unceasingly.After 17 days，larva could swim，of which the yolk sac was absorbed completely，fin and scale began to differentiate uninterruptedly. After floating 40 days，the larvae developed in to juveniles with adipose fin differentiated and scales in both sides covered，of which parr marks began to appear.It may be considered that embryonic development speed of the hybrids was between their parents.Juvenile characters were similar to their parents，too. Morphological characteristics in the early stage of the hybrids was more similar to Hucho taimen，which grew much faster than their parents. It can be concluded that the contribution to hybridization advantage may come from maternal parent.
