Background technique

Artificial reefs are structures that are consciously installed in predetermined waters for the purpose of improving the water environment, protecting and multiplying fish and other aquatic resources, and conducting recreational fishing activities. Artificial reefs have important ecological significance in the management of offshore fishery resources and aquaculture, habitat habitat and biodiversity protection, restoration and protection of fish spawning grounds and nursery grounds, and construction of seaweed farms.

Seaweed is an important primary productivity in the sea area. The constructed seaweed field can provide rich food for herbivorous animals, form a complex and stable food web, and provide a variety of habitats for many marine organisms. At the same time, seaweed farms can also absorb N, P and heavy metals, etc., purify water quality, reduce seawater eutrophication, and prevent red tides.

Larvae are the basis for the replenishment and sustainable use of marine living resources. They are the largest in the life cycle of marine organisms and are the most vulnerable to the environment. Larvae are a sensitive developmental stage with the highest mortality rate in the life cycle. The hatching and survival rate and the amount of survival will determine the occurrence of biological generations, that is, the density of supplementary population resources.

However, the traditional artificial reef has a relatively single function, or it only has the function of attracting fish, or it only has the function of attaching eggs, or it is only suitable for the attachment and growth of algae. juvenile reef type.
