About 8 nautical miles away from Longqi Bay, Ledong Li Autonomous County, Hainan Province, you can see that "Pusheng Ocean Ranch 3" is like a white cruise ship moored in the blue sea. This is a semi submersible anti wind and wave green intelligent breeding and leisure tourism platform, and also one of the "experimental fields" for Hainan to explore and develop modern marine ranches. Modern marine ranching is the "key" to achieving high-quality development of marine fisheries. Here, the sea is vast, the water is good, and it is warm all year round. "Zhong Huiqun, Deputy General Manager of Hainan Pusheng Marine Technology Development Co., Ltd., believes that this" blue ocean "of Hainan Ocean Ranch has great potential. The reporter learned through interviews that the current platform of this modern marine ranch only requires 6 people to operate normally, with most of them being fishermen or farmers. Ji Xinxiang, 45 years old this year, is a local crab farmer who realizes that extensive farming causes damage to the environment and is not a long-term solution. As the "small sea" style aquaculture ponds were gradually phased out, Ji Xinxiang found a new job as a fish herder. The wind speed ranges from 4 to 5 levels, and the wave height ranges from 0.8 to 1 meter. "In the breeding cage of the" Pusheng Ocean Ranch 3 "platform, the cobia swims happily on the waves. Ji Xinxiang is checking meteorological and hydrological data on his mobile phone and underwater images transmitted by intelligent network patrol robots. From the images, abnormal situations such as sick fish, dead fish, or cage blockage can be identified in a timely manner, thereby reducing the workload of divers entering the water, "Ji Xinxiang said. This intelligent operation system for deep sea net cages is the core system for achieving intelligent aquaculture in ocean ranches. Offshore platforms and deep sea net cages need to be equipped with hardware facilities such as surface meteorological systems, profile flow velocity and direction meters, and underwater biological monitoring systems. Ji Xinxiang can accurately grasp the growth status of fish through data, which was difficult to achieve through extensive farming methods that relied on feelings and experience in the past. The reporter saw on "Pusheng Ocean Ranch 3" that the restaurant, guest rooms, photovoltaic power generation devices, network signals, and other facilities are all available, and daily transportation boats transport daily necessities and biological bait. Ji Xinxiang told reporters that the offshore platform can withstand a 17 level Super Typhoon. Compared with fishing at sea or "fishing in the small sea" aquaculture, the working environment is greatly improved, not only the benefits are improved, but also the safety and environmental protection. Protecting and then nurturing is the necessary path for Hainan to develop marine pastures. In order to protect the ecological environment of the sea area, Hainan Pusheng Marine Technology Development Co., Ltd. has put about 15300 cubic meters of Artificial reef into the sea area, of which 13300 cubic meters Feng Chunyun has personally participated. "It takes 6 to 7 hours to locate, tie anchor, release water, and fix a ship type Artificial reef from the water surface to the sea bottom." Feng Chunyun was a ship maintenance worker. He used to escort the ship, but now he has to sink the ship into the sea bottom himself. The reporter learned that Artificial reef can create a natural habitat and shelter for marine organisms at the bottom of the sea. Over time, corals attach and seaweed grows; Shellfish reproduce and digest some of the aquaculture bait. The Artificial reef gradually forms a small ecosystem, which is conducive to the restoration of marine fishery resources. "In the future, the sunken Artificial reef will be built into a submarine landscape, which can be one of the fishing and tourism projects for underwater sightseeing in the marine ranch," said Feng Chunyun.
