Description

Technical Field

[0001] This utility model relates to the technical field of spawning grounds, and in particular to an artificial composite system for spawning grounds. Background Technology

[0002] With the significant decrease in aquatic plant populations in natural water bodies such as rivers, lakes, and reservoirs, spawning grounds for fish that lay adhesive eggs are severely insufficient, leading to a sharp decline in the species and numbers of such fish. For example, the silver carp prefers shallow water areas rich in aquatic plants and rocks, where it lays adhesive eggs that attach to the rocks. However, the silver carp population is already declining, and the degradation of its spawning grounds is a major reason for this decline. To replenish aquatic fish populations and alleviate the decline in fishery resources and biodiversity, it is essential to implement diverse fish habitat restoration measures.

[0003] Floating aquatic plant beds utilize hydroponics, primarily aquatic plants, to establish artificial ecosystems that reduce pollution loads in water bodies. They leverage interspecies symbiosis and fully utilize the ecological niches and nutrient niches of the water. Plants grow in a hydroponically similar environment, their roots naturally extending and floating in the water, absorbing and adsorbing organic pollutants such as ammonia and nitrogen. This provides habitats and attachment points for fish, shrimp, and microorganisms, while simultaneously releasing compounds that inhibit algae growth. Through the combined efforts of plants, animals, and microorganisms, the water quality is improved, achieving the goal of restoring or rebuilding the aquatic ecosystem.

[0004] However, a simple floating structure for planting on water cannot provide a spawning ground for fish that lay adhesive eggs. Therefore, there is an urgent need to provide an artificial composite spawning ground system to solve the above problems. Utility Model Content
