　　Marine aquaculture equipment can not only raise fish, but also a "net celebrity" travel check-in point; seagrass beds can not only attract whooper swans, but also reduce carbon emissions.

At the Northeast Asia Marine Economic Innovation and Development Forum and the 2022 China Marine Economic Forum held on the 10th, technology, humanities, and win-win have become the key words for the guests and experts to discuss the future development of my country's marine ecological economy.

　　In the sea about 2 kilometers away from Fisherman's Wharf in Laishan District, Yantai, Shandong, the "Genghai No. 1" marine ranch integrated platform is like a huge "sea flower".

Three circular cages with a diameter of 40 meters form "petals", and the culture volume of each "petal" is about 10,000 cubic meters.

"Sea Flower" can cultivate 200,000 marine fish each year, with an annual output of about 150,000 kilograms.

　　There are 60 fishing spots on the three "petals", and there is a multi-functional hall of nearly 600 square meters at the "flower heart".

Visitors can go fishing, taste seafood, and enjoy popular science films about marine culture on the platform.

Every year, "Genghai No. 1" can receive 50,000 tourists.

　　Through the hydraulic pile system, "Genghai No. 1" stands firmly on the sea surface.

Wind and solar power generation equipment basically meets daily electricity demand, sewage treatment equipment allows zero discharge of domestic sewage, and seawater desalination technology can produce 20 cubic meters of fresh water per day.

According to the wind direction, sea water flow and other conditions, "Genghai No. 1" can adjust the feeding position and quantity, so as to achieve the effect of scientific feeding and accurate feeding.

　　The application of a series of scientific and technological innovations has made a marine aquaculture equipment a tourism and sightseeing platform.

In the field of marine ecological economy, the primary, secondary and tertiary industries are being deeply integrated.

　　Luo Xuye, a researcher at the National Oceanographic Technology Center, said that in the fields of ocean observation instruments and deep-water platforms, my country already has overall design and system integration capabilities.

In terms of specific technologies and products, my country has achieved a comprehensive tracking of the international advanced level, and has continuously promoted the process of industrialization.

　　In the vast seas of our country, there are many large and small islands.

Experts at the meeting believed that with the development of economy and society, island tourism will become the next breakthrough in tourism development.

However, compared with seaside cities, island tourism requires a longer incubation period.

　　Zhang Haifeng, director of the Island Research Center of the Ministry of Natural Resources, said that my country's island tourism is currently mainly based on natural resources, with insufficient humanistic characteristics, homogenization of tourism products, and imperfect service systems.

　　However, from the needs of tourists, they not only pursue the original ecological environment, but also pay more attention to the quality of service and the human resources of the island.

　　Zhang Haifeng believes that to develop island tourism in the future, the local government should not only create a good ecological environment and invest in infrastructure construction, but also refine the regional division of labor and positioning, especially to improve the creative level of tourism products with unique human resources.

　　In addition, developing a "blue carbon sink" ecosystem to achieve a win-win situation has also become an important topic in this marine ecological economic discussion.

　　It is understood that as the main force of marine organisms that absorb and fix carbon dioxide, mangroves, coastal salt marshes and seagrass beds are internationally recognized as the three major "blue carbon sink" ecosystems.

Tamarix, Suaeda, coral reefs, etc. also have the role of carbon sequestration.

　　In Weihai, Shandong, the local area has carried out large-scale restoration of seagrass beds of algae to create "undersea grasslands" and "undersea forests".

Seagrass beds can provide rich bait for whooper swans, attracting more than 10,000 whooper swans to spend the winter every year, and thus attracting a large number of tourists.

　　Relevant experts said that the development of the "blue carbon sink" ecosystem is becoming a new focus for the development of marine ecological economy.

It can not only help carbon reach the peak and carbon neutrality, but also bring economic and social benefits to the local area, and achieve the win-win effect of green development and harmony between the human and the sea.
