Abstract：The impact of the Pazi Hydraulic Project on fish life and reproduction is primarily manifested in the obstruction of migration channels within the reservoir area,which weakens genetic exchange among fish populations in different water bodies and may lead to a decline in overall genetic diversity.With the continuous improvement of national requirements for ecological environmental protection in recent years,the synchronous construction of ecological fishway facilities alongside new hydraulic projects has become a crucial measure to ensure the smooth passage of fish.The type of fishway facility can be optimized and determined through technical means such as numerical simulation to better satisfy fish migration needs and promote the healthy and sustainable development of the aquatic ecosystem.Fishways hold significant importance in protecting fish resources and maintaining the ecological environment;they constitute not only an engineering measure but also an embodiment of the philosophy of harmonious coexistence between hydraulic construction and natural ecology.
