Abstract
We established large-scale ecohydraulic modelling over 600 km of the upper Yangtze River to identify the critical ecohydraulic conditions that support sturgeon reproduction. Based on the theoretical modeling results, we conducted indoor experiments to optimize the combinations of identified key ecohydraulic parameters. Besides, the construction of the Xiangjiaba Dam in 2006 profoundly altered the hydrological regime and ecohydraulic conditions of spawning habitats of the Yangtze sturgeon. To investigate the impact of these alterations on the quality of spawning habitats, two of the eight historical spawning areas of the Yangtze sturgeon, located near the Xiangjiaba Dam, were examined. The current habitat conditions at these two spawning areas were estimated from the recently collected bathymetric and hydrological data.
