Abstract: In order to study the reproductive status of drifting egg-producing fish in the lower reaches of Jinsha River, and to provide scientific basis for the fish conservation, the fish resources surveys of early life history stage were carried out in the Qiaojia section, the lower reaches of the Jinsha River during May to July in 2017 and 2018. The results showed that there were at least 14 species (subspecies) of fish bred in the lower reaches of the Jinsha River, including 12 species with drifting egg and 7 endemic fishes in the upper reaches of the Yangtze River. The amount of drifting eggs laid by fish was estimated 6 949.73×104  individual in 2017 and 11 056.17×104  ind. in 2018, among which 3 861.44×104 ind and 5 338.16×104  ind was produced by the endemic fishes, respectively. Five peaks of spawning activities (two in 2017 and three in 2018) were detected during the surveys, with a spawning amount of 7 942.02×104 ind, accounting for 42.67% of the total spawning scale in two years. Pearson Correlation analysis showed that the discharge of fish eggs was significantly and positively correlated with water temperature (p < 0.01) in 2018. The peaks of spawning activities for the endemic fish species such as Coreius guichenoti, Leptobotia elongata and Jinshaia sinensis all appeared when the flow velocity increased. The spawning grounds of fish with drifting eggs ranged from the reaches of Qiaojia County to Panzhihua City. Specifically, In 2017, the spawning sites mainly located in the reaches of Qiaojia County, Huize, Huidong and Jiaopingdu. Besides, Wuding section was found in 2018 as well.Compared with the previous results, our study indicated that the spawning egg abundance maintained stable and spawning grounds were more disperse in the lower reaches of the Jinsha River although the number of endemic fish species increased in our surveys.It is suggested that the study on resources of drifting eggs in the lower reaches of Jinsha River should be strengthened, especially on artificial propagation technology of endemic fish species. Meanwhile, ecological operation of dams should be conducted scientifically, which, particularly, are suitable to meet the demand of fish spawning in the lower reaches of the Jinsha River.
