Description

technical field [0001] The invention relates to the technical field of aquatic biology, in particular to a device and method for hatching and cultivating portable fish egg fry. Background technique [0002] In recent years, the development of hydroelectric cascades in major river basins has developed rapidly and has become more and more complete. While bringing economic and social benefits, it has also brought about a series of water ecological environmental problems, especially for aquatic organisms represented by fish. , resulting in a significant reduction in fish resources in some river basins, and some fish species in some river sections are endangered or even disappear. The cascade joint ecological dispatch of major hydropower stations in the basin is a favorable and important measure to improve the ecological water environment of the basin and the habitat conditions of important aquatic habitats. The important research content of the evaluation of the cascade joint e...
