This project is aimed at the improvement of environmental facilities for the selection and breeding of seawater ornamental fish. The existing pattern field space is used to improve the mechanism of biological bait cultivation, feeding and feeding during the breeding period, and systematic improvements are made to facilitate the completion of automated breeding experiments. The breeding trials at the seedling stage will be carried out and the relevant water quality, water supply, growth, bait and other data will be collected as reference materials for facility selection and breeding. Based on the demonstration field, the optimized nursery breeding environment and bait conveying system are developed to provide intelligent networking functions that are more accurate and labor-saving, and provide practical farm application. Cultivate ornamental aquarium breeding and intelligent modular facilities and equipment, and improve the environment of the economically beneficial breeding farm through modularization, and use functional modules and breeding fish behavior identification systems as future models of ornamental fish breeding for set up specification functional facilities to effectively implement industry upstream and downstream integration.
