Review on hydraulics research of fish eggs’ movement in rivers
摘要
Abstract
The transport of fish eggs is an important stage in its early ontogeny, which relates to hatching success and population recruitment. An understanding of the eggs’ movement has the potential to obtain a better estimation of egg abundance,guide the rehabilitation of spawn grounds,evaluate the effect of ecologi⁃cal measures and create strategies for protecting fish resources. Taking eggs of Chinese sturgeon and four major Chinese carps for examples, this paper summarized the main influence factors of eggs’ movement and reviewed the relevant research methods and results from hydraulic aspect. The influence factors includ⁃ed the eggs’ physical and biological characteristics, river morphology and hydrodynamic conditions. The main research methods included survey on fish early stage of ontogeny, drifting experiment with tracers, flume experiment and numerical simulation. Meanwhile, this paper pointed out that most of the researches on eggs’movement only showed the phenomenon,but did not explain the reason or mechanism for the phe⁃nomenon. It should be necessary to carry out more flume experiments to reveal the principle of eggs’move⁃ment and the influence mechanism. In simulation of eggs’ movement, the dimension and scale problem should be well concerned. It is also of importance to reasonably generalize the ecological characteristics of fish eggs for the simulation of eggs’evolution and movement. The eggs’movement is a multidisciplinary re⁃search. So,how to use the method of sediment movement and integrate the fish ecology,hydraulics and riv⁃er dynamics will be the direction of future research.关键词
