摘      要：Conservation of endangered or economic fish and control of invasive fish is a great challenge of hydraulic engineering *** velocity has been recognized to affect the spawning of fishes delivering drifting eggs in ***,solid scientific supports and associated mechanisms to establish quantitative relations between flow velocity and fish reproduction,taking into account spawning,fertilizing,hatching,as well as surviving,are *** this paper,we quantified the relationship between flow velocity and reproduction of Chinese carps through both lab and field *** results showed that a minimum velocity was required to trigger Hypophthalmichthys molitrix(***)releasing eggs,and a velocity range was preferred to sustain spawning ***,the embryo incubation and larvae development of *** were found to be inhibited with the increase in flow *** the requirements of spawning and hatching,as well as larvae surviving,an optimized flow velocity processes was identified for the reproduction of *** in *** findings were of great significance to the adaptive operation of reservoirs to create reasonable and precise ecological flows for managing fish reproduction,as shown by the promising results in the engineering application to the Three Gorges Reservoir.
