Abstract: In order to estimate the resources status before the storage of Baihetan and Wudongde hydropower project, surveys of Ichthyoplankton resources were carried out in Jiaopingdu section of the lower Jinsha River from 2016 to 2018. The results showed that there were 7 fish species with drifting eggs, five of which were endemic to the upper Yangtze River, including Jinshaia sinensis, Leptobotia elongate, Coreius guichenoti, Rhinogobio ventralis and Leptobotia rubrilabris. In 2016, 2017 and 2018, the total eggs quantity of fish with drifting eggs were 0.21×108 ind, 0.22×108 ind and 0.25×108 ind, respectively, and spawning grounds were located in Yuanmou, Yongren, Pingdi, Jinjiang and Geliping sections. Sections above the Jiaopingdu were large in scale of fish with drifting eggs, which will be inundated after the storage of Jinsha River second stage project, and then the propagation of fish maybe affected. It is suggested that the spawning habitat should been protected and restored in flowing sections of mainstream and tributary above the end of Wudongde reservoir based on the results of the research.
