Provided is a culturing facility comprising: a rearing water tank for rearing a cultured fish stock; an inspection device for performing a non-destructive inspection of a living cultured fish stock; and an information processing device that derives information relating to the amount of at least one organ on the basis of an inspection result acquired by the inspection device. Provided is a method for culturing fishes, comprising a selection step for selecting a parent fish from a cultured fish stock on the basis of information relating to the amount of at least one organ acquired during a non-destructive inspection of a living cultured fish stock.

The application discloses a marsh habitat multi-element integrated promotion method based on biological difference requirements, and belongs to the technical field of wetland ecological restoration. The method first carries out biological resource investigation and water quality monitoring on the target marsh area, establishes the corresponding relationship between the biological community life cycle stage and the habitat element demand, and then divides the area into a clear water structure type habitat promotion area and a food supply enhancement area. In the clear water promotion area, complementary submerged plant combinations are used for restoration, and in the food supply enhancement area, local fish stocking is implemented by constructing a containment unit, and the water eutrophication state is monitored in real time. The effect evaluation is completed through regular ecological monitoring. The application is oriented to biological differentiation requirements, cooperatively regulates water quality, food supply and habitat structure, has stronger restoration accuracy and stability, can effectively improve the suitable living conditions of the key life cycle of multiple types of organisms, and optimizes the structure and function of the marsh wetland ecosystem.

This invention discloses a method and system for allocating fish stock enhancement quotas in plateau lakes and reservoirs based on ecological carrying capacity analysis. The method includes: acquiring lake / reservoir environmental perception information; preprocessing the information and constructing a distribution map of lake / reservoir environmental parameters; extracting multimodal features from the environmental parameter distribution map to generate multimodal fusion features, constructing an ecological carrying capacity analysis model, and performing ecological carrying capacity analysis on the target plateau lake / reservoir to obtain ecological carrying capacity analysis information; introducing a quantum evolutionary algorithm to combine the ecological carrying capacity analysis information and the multimodal fusion features to perform fish stock enhancement quota analysis and generate a stock enhancement quota scheme; conducting spatial value assessment of the target plateau lake / reservoir to generate a value heatmap; and using an ant colony optimization algorithm to optimize the stock enhancement quota allocation path to obtain a stock enhancement allocation path network to assist in fish stock enhancement quota allocation in the lake / reservoir. This improves the effectiveness and ecological stability of fish stock enhancement in plateau lakes and reservoirs.
