Mariculture in China has been greatly developed in the last decade, and is the only country in the world where the culture yield exceeds the fishing yield. The ecological fishery can realize the culture production of specific aquatic organisms in a specific fishery water area environment, and realize the hierarchical multi-level energy conversion and material circulation among producers, consumers and decomposers in a fishery ecological system, and is a continuous, stable and efficient fishery production mode. In recent years, the concept and mode of ecological fishery are perfected and continuously developed, and higher requirements are also put forward for the culture mode.
Under different types of ecological fishery culture modes, on one hand, the quantity and the quality are required to be improved in production, and stable and healthy output is provided; on the other hand, the adverse effect of cultivation on the environment is required to be reduced as much as possible, and sustainable development is realized. The single-kind culture technology is relatively mature, wherein the culture area of the economic seaweeds such as kelp and asparagus suitable for culture on the water surface in China is continuously enlarged, and great contribution is made to carbon sink in China; economic seawater fishes such as large yellow croaker, Sebastes schlegeli, yellow croaker and the like have increasing specific gravity in the seawater aquaculture industry of China, and provide very high economic output for the development of the seawater aquaculture industry of China. However, in the current cultivation process, the condition of excessive cultivation of a single variety generally exists, and how to perform ecological cultivation by means of different ecological niches among multiple varieties and support the conversion of the quantity type to the quality type of the marine cultivation industry in China becomes an urgent priority.
The algae has strong ecological function in an ecological system, can provide stable primary productivity, provides shelters, refuges and spawning sites for fishes, and has extremely high ecological significance in the mixed culture of the algae and the fishes in open water areas. The multi-variety and three-dimensional ecological culture mode has been explored and tried in the mariculture processes of pond culture, net cage culture, raft culture and the like. The utility model CN 203040415U discloses a proliferation reef suitable for multi-element mixed culture of fish, ginseng and abalone. The precious marine product proliferation reef comprises a reef body shell and abalone and sea cucumber proliferation reefs loaded at the bottom of an inner cavity of the reef body, wherein the reef body shell consists of a prismoid frame type base and a square frame type reef body shell and is formed by pouring reinforced concrete, and the abalone and sea cucumber proliferation reefs are stones or other small proliferation reefs loaded at the bottom of the inner cavity of the whole reef body. After the whole precious marine product proliferation reef is thrown into the flat seabed of a designated sea area, stichopus japonicus and abalone fries are thrown into the reef, and the algal abalone and stichopus japonicus diversified culture is realized by naturally luring and collecting reef-loving fishes. The utility model discloses a reef body facility can be used to the many units such as fishes, sea cucumber and abalone and synthesize and breed, has improved product output and quality, is favorable to realizing the comprehensive utilization of habitat restoration and sea area. The patent mainly aims at the breeding of the rare marine animals such as fish, abalone and ginseng, the seaweed resources required by the stable balance of the regional marine system are not supplemented, the hidden danger of severe disturbance to the natural environment exists, especially, the abalone has severe ingestion intensity to the seaweed resources, the environment deterioration and the ecological system unbalance are easily caused, and the deep connotation of ecological breeding cannot be completely reflected.
In the wind sheltering area around the island, the general water body is calmer and is less disturbed by wind waves, which is beneficial to the accumulation of nutrient substances, provides a material foundation for the growth of algae, and simultaneously provides a good sheltering place for fishes loving reefs. At present, the work of fish-based and algae-fish mixed culture is less, and particularly, the development of ecological fishery which mainly takes natural resource growth and protection in natural sea areas is very little, mainly because the scientific transplanting technology of algae has technical and facility difficulties, and the research and development of related technologies and facilities are urgently needed to solve the problem.
