This invention relates to the field of aquaculture engineering technology, and discloses a gravity-based three-dimensional polyculture system for fish, shellfish, and algae based on intelligent monitoring, and its control method. The system includes a polyculture system net, which is used to optimize ecological efficiency when fish, shellfish, and algae are polycultured. The net contains polyculture support components. In this invention, the polyculture system net enables three-dimensional, stratified polyculture of fish, shellfish, and algae, establishing a complete trophic cascade relationship. Fish uneaten feed and excrement are filtered and utilized by mid-layer shellfish, shellfish metabolites promote the growth of bottom-layer algae, and algae photosynthesis oxygenates the system and absorbs eutrophic salts, forming a closed-loop, highly efficient ecological cycle. Combined with dissolved oxygen sensors, flow meters, and multi-dimensional water quality sensors for collaborative monitoring, the culture density at each layer can be precisely controlled, increasing the system's material conversion efficiency by more than 30% and reducing feed input by 25% compared to traditional monoculture models.
