In order to protect the marine ecology, Zhanjiang has implemented a policy of reducing the number of fishing vessels without increasing them, and actively guided fishermen who have reduced their boats to switch to marine aquaculture. Fishermen who have switched to other industries are creating smart ocean ranches to provide the market with more high-quality seafood products.

Recently, the joint research and innovation team of the South China Sea Fisheries Research Institute of the Chinese Academy of Fishery Sciences, including Associate Researcher Li Gen and Researcher Huang Xiaohua, has made new progress in intelligent monitoring methods for deep-sea aquaculture.

On the coast of the South China Sea, in the vast blue territory, through the "Hengyi 1" aquaculture platform for deep sea aquaculture, Kanpachi fish, Seriola quinqueradiata, grew to eight pounds in just four months. What are the secrets behind it? How to firmly grasp the "Chinese core" of fisheries and intelligently cultivate the "blue granary" from seed industry, breeding, equipment to deep processing? What technological innovations are behind the high-quality development of the marine industry?

Based on the advantages of net cage aquaculture, adopt the production mode of "company+base+fisherman", encourage and support capable and powerful aquaculture enterprises and large-scale breeders to develop gravity based deepwater net cages, and have put 254 reinforced gravity based deepwater net cages into operation.

The report shows that in 2023, the crayfish aquaculture area was 29.5 million mu and the output was 3.161 million tons, an increase of 5.36% and 9.35% respectively year-on-year, continuing to maintain rapid growth. The crayfish aquaculture output accounts for 9.26% of the total freshwater aquaculture output in China. Among them, the comprehensive cultivation area of rice and crayfish is 25.3 million mu, and the output of crayfish is 2.75 million tons, accounting for more than 80% of the national crayfish cultivation area and output.
