[Explanation] In Paixi Village, Shangen Town, Wanning City, Hainan Province, there is a land-based "ocean pasture"-a land-based coral and clam cultivation base. The artificially cultivated corals, giant clams, seaweeds, and fish form a small ecosystem. After multiple filtrations through the food chain, zero emissions of pollutants and zero breeding medicines are finally achieved. The grown corals and clams will eventually be released into the sea and used to restore the marine ecological environment.

  [Explanation] In 2013, when Wang Yuan, a Beijinger, came to Hainan as an aquarium creature enthusiast, the cultivation of corals and clams is still blank. After years of continuous exploration, he and his team finally created the land-based "ocean pasture" of their dreams. At the same time, they have broken through hundreds of coral and marine fish breeding technologies and filled many domestic and international gaps. At present, the South China Sea Institute of Oceanography, Chinese Academy of Sciences is cooperating with them to carry out scientific research projects on artificial breeding of corals and clams.

  [Same period] Wang Yuan: For this artificial land-based coral reef ecological marine pasture, we will also adopt this modular form. It can be combined with ornamental fish and aquatic products. We can produce a large number of coral seedlings every year and then use them for ecological restoration. In this way, we can use low-cost models and fast ways to repair the ecology of the ocean.

  [Commentary] The reporter saw in Wang Yuan's "Ocean Ranch" that transparent glass water tanks lined up. Sunlight shines into the water through the roof of the glass house. Various colors of tropical fish, corals, giant clams, seaweeds and other sea vivid plants present a colorful scene. The reporter noticed that most of the corals in the water tanks grew on a movable base, and the whole coral could be taken out by pulling out the base.

  [Same period] Wang Yuan: It is very convenient for divers to fix this outer bud part on the seabed (artificial reef) by diving, so that we can plant a large number of corals in a short time. One of these corals quickly forms a complete ecology in the sea, and the other one can also quickly reproduce sexually.

  [Explanation] Wang Yuan introduced that at present, this land-based "ocean pasture" can completely rely on sunlight as the driving force. The food fed through the multiple filter food of the food chain organisms is completely decomposed and used, and eventually melts into a part of the entire ecosystem The entire breeding process does not use any drugs, so it can achieve zero-emission pollutants and zero-drug organic ecological farming. He said that coral reef ecology is the most productive ecosystem in the world. The principle of land-based coral reef ecological marine pasture is to simulate the coral reef ecology of the sea on land, and the grown corals and clams can be released to the sea to repair the ocean. ecosystem.

  [Same period] Zhou Hailong, a researcher at the State Key Laboratory of Marine Resources Utilization in the South China Sea (Hainan University): Wang Yuan's artificial (coral) sexual reproduction can obtain a large number of coral seedlings at a relatively fast rate, and then carry out indoors for a period of time The cultivation can grow to a certain size. In this way, we can transplant the coral he cultivated to the environment that needs repair and the site is suitable for coral growth without affecting the original coral reef ecosystem. So this positive effect (for the restoration of marine ecosystems) is beyond doubt.

  [Explanation] Zhou Hailong said that Wang Yuan ’s land-based “ocean pastures” can more intuitively introduce the importance of coral reef ecosystems than traditional marine pastures, and provide an excellent platform for popular marine ecological knowledge. .
