A few days ago, the first batch of multi-layered ecological aquaculture carried out by the Pulandian Bay Mariculture Experiment Park in Pulandian City, Liaoning Province, was the first to succeed, providing a reliable scientific basis for the high-efficiency and ecological development of the beach culture.
The water quality of the Bohai Sea is about 4% higher than that of other sea areas, and the technical requirements for aquaculture are higher. In the past, Pulandian City used Yellow Seawater to carry out two-layer culture experiments with different combinations of flowers, prawns and sea cucumbers. This was not only a three-layer culture experiment, but also the first use of Bohai Seawater. This year, 1.2 million Oriental prawns and 200,000 “Jiangsu Red†cotton seedlings were introduced and introduced. Scientific and technical personnel adopted scientific methods and technical means to successfully solve the problems of poor water quality, pH value and salinity. By the harvest season, the average weight of cottonseed meal is 2.5 kg and the average body size of shrimp is 10 cm. It is reported that, in the next step, researchers will increase other organisms such as Conch, and conduct different experiments on mixed three-dimensional culture.
