Abstract

The invention discloses a portable device and method for hatching and culturing fish eggs and fries. The device comprises a tank body, wherein a water storage bin, a fish egg temporary culture bin, afish egg hatching bin, a fish fry breeding bin, a circulating water filter bin, a filtered water temporary storage bin and a power bin are arranged inside the tank body. According to the device, hatching of fish eggs and culture of fish fries can be realized at the same time due to multiple bins having different functions, the actual requirement for early fish resource investigation and research for river fish spawning site can be met. The device is applicable to simultaneous constant sorted culture of multiple fish eggs and fish fries collected from the river fish spawning site, has the advantages of refined modular design, constant and stable operation, external-connected or built-in power supply, carrying convenience, simple operation, strong practicality and the like, and is suitable for large-scale popularization and application.

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...
