Kimura early development of the whole process was investigated. According to the exterior appearance and typical characteristics of the embryo, the process of embryonic development was defined into 25 minor periods and described in detail. The result showed that the total accumulated temperature was 228.31℃·d at an average water temperature 10.2℃ from fertilization to hatching, the fertilized eggs hatching lasted 549 h. The mean total length of newly hatched larvae was (11.62±1.00) mm, the mean body weight of larvae was (0.0254±0.0016) g, the yolk sac volume of larvae was (53.82±1.03) mm³. Primordia dorsal, anal primordia, pelvic primordia, adipose fin primordia appeared respectively on days 2, 4, 9, and 11. The first chamber air bladder was formed on 17 d. Larvae began into the mixing vegetative stage on 18 d. First scales appeared in the larva of abdomen, entered into juvenile stage on 20 d. The yolk sac was completely absorbed, juvenile completely exogenous nutrition on 26 d. All fins completed development on 52 d. Stripes appeared completed development on the body surface on 64 d. The scales fully distributed the body on 73 d, entered the young period. Growth model equations fish larvae period is: TL=0.3766: days of age), the specific growth rate was 0.030. This study aims to provide scientific guidance for the Sichuan taimen artificial breeding and fry cultivation.
