The technical path verification of the far -reaching marine ship breeding for the first time, the first cabin of "Guoxin No. 1" was arrested and listed

After more than three months, more than 3,000 nautical miles of maritime patrols, the technical path verification of far -reaching maritime ship breeding for the first time

"Guoxin No. 1" first cabin big yellow croaker is arrested and listed

On the afternoon of September 1st, the world's first 100,000 -ton smart breeding ship "Guoxin No. 1" breeding was launched and launched. The golden yellow croaker is "fishing out" from the fish pump and transferred to the dormant pool through the conveying system. The first batch is expected to catch up to about 65 tons of big yellow croaker.

Since the delivery of operations on May 20, the "fishery aircraft carrier" has cruised more than 3,000 nautical miles at sea, from south to north, from spring to autumn, and finally ushered in this golden gain.

For more than three months, the Minister of Breeding Technology Qu Shancun followed the "Guoxin No. 1" to run in the Yellow Sea and the East China Sea. Miscellaneous. For more than three months, the breeding team carefully "cares" the first batch of fry entering the cabin, but it is still inevitable to encounter various "accidents" that make them anxious. The world's first batch of big yellow croakers in the "carrier -carried" mode also saved one hand of technical data and information.

The starting list of the first batch of big yellow croakers means that the "ship carrier -carried" model represented by the "Guoxin No. 1" is successful at the technical level. For the first time, Qingdao has completed the technical path verification of far -reaching marine ship breeding in the world.

"Guoxin No. 1" maritime cruise breeding big yellow croaker.

Chasing "temperature" all the way northward

The "Guoxin No. 1" is moored at 28 nautical miles of Zhengdong East of the Yellow Sea. After collecting the fish gap, Qu Shan Village stood on the deck and looked west to enjoy a rare time. The process of breeding for more than three months was full of embarrassment and anxiety. The moment his heart was "landed" until the moment he collected the fish.

"No one has raised fish like this, we have no experience to learn from." Qu Shancun admits that the first sailing journey of "Guoxin 1" is not smooth sailing. "Storm".

On May 20th, the "Guoxin No. 1" delivered from Qingdao to the waters of Ningde, Fujian for the first batch of fish seedlings to enter the cabin. The most suitable growth temperature of big yellow croakers is 22-26 degrees Celsius. Under the "ship carrier -carried" mode, the farmers can change from air temperature and environmental changes. They choose the most suitable waters such as water temperature, ocean currents, and climate to create the best growth environment for fish.

As a result, the mobile "marine pasture" chased the "suitable temperature" all the way north, and arrived in the Zhoushan waters in Zhejiang in mid -late June. In order to avoid typhoons, it continued to enter the Yellow Sea area in early July.

After entering the Yellow Sea, the "Guoxin No. 1" unexpectedly encountered the edge of the Yellow Sea Cold Water Group. In the waters of cold water, the temperature difference between the surface layer of the seawater is larger than the underwater temperature difference. "Guoxin No. 1" mainly uses large -scale seawater pumps to extract the seawater near the bottom of the ship to the breeding warehouse to achieve the uninterrupted exchange between water and natural seawater in the cabin. "Guoxin No. 1" eats about 14 meters under normal breeding conditions, and the power pump has a large power. Sea water with water depth of about 20 meters can be drawn to the breeding cabin. In the case of the temperature of the seawater surface layer exceeding 20 degrees Celsius, the temperature of the water body at 20 meters has been as low as a dozen degrees of Celsius, and the water temperature in the breeding cabin decreases significantly after the water body exchange, which has a greater impact on the breeding of the big yellow croaker.

The "Guoxin No. 1" of "Cold War" quickly transferred the anchor to find a new anchor near the Yellow Sea Cold Water Group.

In the intelligent management and control center of the ship's end, the breeding personnel conduct centralized control and real -time monitoring of water, oxygen, light, feed, and fish in the breeding cabin through the 2108 testing point information of the entire ship.

They found that the big yellow croaker in the breeding cabin likes to gather but does not like the light. The lights of the underwater camera are avoided as soon as the fish is turned on. After feeding the feed, the fish will swim to the water as soon as the sound of the feed machine starts. Eat. They also found that the big yellow croaker when the catcher would become golden and golden under dark and hypoxic environmental conditions, and the color was more beautiful.

The survival rate exceeds 90%of the breeding cycle is a quarter of a quarter

Tian Naidong, the project and business director of Guoxin Zhongshi (Qingdao) Marine Technology Co., Ltd., introduced that the controllable closed breeding environment of "carrier -carried cockts" is more likely to isolate the source of the disease and enhance the survival rate of breeding. The results of the acceptance before the arrest show that the results of the first cabin are better than expected. The survival rate of big yellow croakers is as high as 90%, which is higher than the traditional breeding method of 70%-80%.

From the perspective of breeding density, the actual production capacity of the first cabin is also better than the traditional breeding method. The first batch of big yellow croaker breeding exceeds 20 kilograms per cubic meter, while the breeding density of ordinary cage breeding can only reach 8 kg per cubic meter. From the perspective of growth rate, the cabin fry grows rapidly in three months, and the weight gains by 100-200 grams, far exceeding the growth rate of breeding big yellow croaker in ordinary cages, and a quarter of the breeding cycle can be shortened.

The neatly arranged big yellow croaker runs quickly on the conveyor belt, from the fish water separation area, the dormant pool to the pre -cold pond, and the freezing processing area. "The first batch of big yellow croakers to catch the entire process of entering the cabin, transfer, growth, quality control, and capture, and verified the feasibility and effectiveness of the" ship carrier -carried maintenance 'model. " Xu Hao, director of the Institute of Mechanical Instrument, said.

During the first batch of big yellow croaker breeding, breeding technicians continued to improve the "ship carrier" technology through data accumulation and analysis. "Guoxin No. 1" has clarified the key indicators of the best growth environment for the breeding of the baron breeding, and basically identified key breeding process parameters such as feed nutrition, feeding strategy, disease prevention and control, breeding density, and growth characteristics. At present, the "Guoxin No. 1" has been approved by the Ministry of Agriculture and Rural Ministry of the country's only far -reaching maritime breeding ship operation pilot, and was included in the "Advanced Manufacturing and Modern Service Development Special" in 2022 by the National Development and Reform Commission.

Fifty farmers will be built in the next five years

The first batch of big yellow croaker on the listing of the Douyin platform was quite sensational on the day of sale. This 8.5 -hour full -scene interaction opened a new stage of industrialization operation of "ship carrier -carried" big yellow croaker.

Mature and copied profitable models are an important guarantee for the sustainable development of the workmade cabin. Not long ago, Qingdao Guoxin Group also organized a Yu Xianye brand release and "Guoxin No. 1" Gongboa Big Yellow Cain Merchants Conference, which officially set up a brand for "ship carrier -carried" big yellow croaker, and gradually improved the marketing network system system Essence

Large -scale farming will reduce the cost of breeding and accelerate the industrial operation of farm breeding. At present, the design of the "Guoxin 2-1", "Guoxin 2-2" and the 300,000-ton oversized farmers design is continuously promoting. With the successive establishment of farmers' ship fleets, the scale effects gradually appear, and the depreciation and amortization of ships will gradually decrease. At that time, the cost of breeding will be mainly concentrated on feed and seedlings. In the future, "Guoxin No. 1" will still have room for improvement in breeding density, energy consumption, and orderly breeding methods.

"In fact, 'Guoxin No. 1' has been preparing for the operation of the subsequent shipwriting." Tian Naidong said that in addition to the main breeding variety of big yellow croakers, "Guoxin No. 1" also raised small yellow croakers and silver catfish to explore other fish breeding varieties The technology and specifications of workers.

In the next five years, Qingdao Guoxin Group will invest in the construction of 50 farmers, forming a far -reaching maritime breeding industry chain with a total tonnage of 10 million tons, an annual output of 400,000 tons of seafish, and an annual output value of 50 billion yuan. The picture is strong and the ocean is the ocean to create a "blue granary" at sea. (Qingdao Daily/Guanhai Journalist Wang Wei)
