"Grazy" in the sea has become a reality!

When it comes to the ranch, most people think of vast grasslands. Today, the deep blue maritime ranch is also giving birth to vitality. On June 1, my country's first national standard "Technical Guide to Construction of the Marine Ranch", which was established in China, was officially implemented, and "grazing" in the sea became a reality!

Looking at the Long Island at the intersection of the Yellow Sea and Bohai Sea, there are platforms on the sea. This is the "Over -Sea" series of deep -sea intelligent cages independently developed by my country. Only a few people can automate and intelligent farming hundreds of thousands of tails. Fish, realize "Tibetan grains in the sea" and "Tunyu and the sea". These smart cages and maritime platforms are the implementation of marine pastures.

The waters of my country are vast and rich in marine resources. The area that can be used for breeding is more than 1.2 million square kilometers. In recent years, fishery resources have been over -mining, offshore fishery resources have severely declined, and marine ecological environment has been damaged. How to protect and repair marine resources and ecology, and achieve sustainable use of fishery resources? When the land is loaded, can the ocean become a new "granary"? How can we protect the marine ecological environment while using it? Building a marine pasture is a good idea.

Ocean pastures are in specific waters, through measures such as artificial fish reefs, proliferation release, ecological breeding and other measures, to build or repair marine biological reproduction, growth, bait or avoiding the enemy's need for the enemy. In the same way, plans and purposeful maritime reservation of marine resources such as fish and shrimp.

Compared with traditional fisheries, ecological benefits are the most significant characteristics of marine pastures better than traditional breeding methods. Ocean pastures are divided into two parts. The smart cages and breeding platforms on the sea are the carrier of industrialized ecological breeding and intelligent monitoring, and underwater is a three -dimensional "underwater community". Artificial fish reefs are houses built for marine life. They can raise the bottom plane of the sea and allow marine life to attach, gather, and inhabit. It is a "ecological bank" under the sea floor. The seaweed seagrass provides bait and habitats for fishery biology, but also absorbs and transforms nutrients in the water body, improves the water quality and environment of the sea area, and proliferates through underground proliferation, which can increase the fishery biological resources.

The underwater seasons are a "blue granary" for environmental protection, resource maintenance and fisheries.

In addition to ecological benefits, marine pastures also bring considerable economic benefits to fishermen. With the marine pasture, the company and small and medium -sized farmers will sign a fish contract to facilitate farmers to cultivate in accordance with standards and requirements. After achieving a certain specification, the company will acquire it at higher market prices and further put them on the cage of the marine pasture. Continue to breeding China to form a "relay farming" of farmers and marine pastures, eliminating the worries of fishermen.

For farmers with difficulty breeding and technical support, marine pastures will cooperate with retail fishermen. In Yantai, Shandong, marine ranch companies have formed a professional cooperative of fishermen to achieve "big fishing belts small fishing" by integrating the waters. From eating by the sky to the door -to -door assistance, fishermen increase their yields and income. Ocean pastures are about 7,000 yuan/mu for direct economic benefits each year, and each annual economic benefits are increased by 50,000 to 80,000 yuan per year. The three -dimensional breeding model of the upper layer of algae, middle shellfish, and underlying fish farming has increased the economic benefits of the perurone by more than 2.5 times.

Economic benefits are also driving the development of related industries. While promoting the transformation of traditional fisheries to leisure and fisheries, experience fisheries, and cultural and fisheries, it also drives the related industries of hydraulic products, fishery equipment manufacturing, catering and tourism, transportation industry, retail industry, craftsmanship and commercial investment develop.

Today, traditional fishermen have become fishermen of leisure fisheries, their income has doubled, and their lives are more comfortable. In Shandong, marine pasture expands the comprehensive functions of tourism, fishing, catering, culture, and science popularization, integrates development with the second and third industries, and builds a leisure and fishery demonstration base. A marine pasture drives tourism consumption and output value of about 500 million yuan throughout the year.

At present, many provinces and cities across the country vigorously promote the construction of a national marine ranch demonstration zone.In the future, marine pastures will take digitization and systematic as a driving force to promote the ecological, precise, and intelligent development of core technology, and have the "smart brain". In Fujian, Taiyuan Shipbuilding Co., Ltd. independently developed "Taiyu No. 3" deep -sea breeding platform, which uses hydraulic twisted motor to drive the wire rope to achieve the rotation of the cage, which not only saves costs, but also reduces the risk of typhoons and seawater damage. Essence.The platform introduces a comprehensive management system of modern marine pasture, with an intelligent monitoring system, living water cabin, and feed fresh -keeping library, which integrates deep -water breeding, water quality intelligent monitoring, and sea leisure sightseeing.

my country's national marine pasture demonstration zone has reached 153. According to the "National Ocean Ranch Demonstration Zone Construction Plan (2017-2025)", 2025 will create 200 national marine ranch demonstration zones. In the future, marine pastures will continue to exert comprehensive benefits and promote the future of sustainable development at sea.
