Description

Technical Field

[0001] The present invention relates to a marine aquaculture system and method. Background Art

[0002] Existing marine ranches are generally divided into fixed structures or mobile structures.

[0003] At that time, fixed structures generally used artificial reefs, but the problem was that harvesting was difficult, it was not suitable for deep-sea aquaculture, it was not suitable for migratory fish, and when strong typhoons or large-scale marine pollution occurred, it would lead to harvest risks.

[0004] Mobile fish farms are easy to move, facilitate later fishing, and facilitate centralized management of fish stocks, thus avoiding the risks associated with fixed farms to a certain extent. However, they also require the constant coordination of the operating vessel captain, making it difficult to distinguish the grade of fish, resulting in a mixture of healthy and weak fish. This lack of grade separation affects the taste of the fish. Furthermore, the fry are easily eaten by larger fish or escape from the cages, resulting in waste. If the mesh size is too dense, it will cause high resistance and poor water exchange.

[0005] Moreover, dead fish cannot be discharged in time, causing pollution or introducing diseases.

[0065] Step 2: Perform fry maintenance;

[0066] Step three, stocking big fish;

[0067] Step 4: Perform system maintenance;

[0069] As a further improvement of the above technical solution:

[0070] First, the fry box is placed in the designated sea area with the help of the pulling rope; the weighted anchor is put in; then, the fry is put into the fry box through the feeding pipe of the batching group B;

[0071] The growth status of the fry in the fry box is observed by a camera. When the number of fry counted in a set unit interval is greater than the set value ratio NA%, and the number ratio NA% exceeds the set threshold, the lower telescopic top rod D is activated to raise or lower the cage body D so that the mesh of the fry inner box and the cage frame B coincide with each other. Under the action of the ocean current, the fry enter the cage frame B; at the same time, fish food is fed into the cage frame B through the feeding pipe of the ingredient group A to lure the fry into the cage frame B;

[0072] The camera is used to observe the growth status of the fry in the fry box. When the number of fry counted within the set unit interval is less than the set value NB, and the number NB exceeds the set threshold, the feeding pipe of the ingredient group B is activated to send in high-pressure fresh water or salt water with a higher concentration than seawater to drive the fry in the fry box;

[0073] When the fresh water or salt water reaches the set time, the fry in the seed box is deemed unhealthy;

[0074] Then the lower telescopic rod D is activated to lower or raise the net box D, the mesh of the seedling inner box and the net box frame B are misaligned, the pump station is activated, oxygen and fish food are fed into the seedling inner box through the feeding pipe for a set time, and then the pump station is reversed to pump water through the feeding pipe to extract the fry in the seedling inner box; after that, the water quality is tested at set intervals and new fry are added;

[0075] In step 2, nutrients and / or medicines are regularly added to the seedling box based on the collected data;

[0076] According to the collected data, nutrients and / or drugs are regularly added to the cage frame B;

[0077] In step 3, inside the cage frame B, the fish and seawater conditions are regularly observed through a camera, and nutrients and / or medicines are added through the feeding pipe of the cage frame B;

[0078] In step 4, according to the hydrological, weather and ocean current information, the cage frame B is regularly towed to cruise in the ocean to achieve automatic water exchange;

[0079] In step 5, the camera is used to observe the growth of the fry in the cage frame B. When the number of fry in the set unit interval is greater than the set value, the number ratio NC% exceeds the set threshold value;

[0080] Then the net cage assembly below, to the surrounding of the net cage frame B;

[0081] Start the telescopic rotating assembly and enter the corresponding mesh hole E on the side wall of the cage; rotate the telescopic rod into the cage assembly and connect it with the cage assembly as a whole;

[0082] The pulling arm controls the shoulder step to drive the cone nozzle B to extend forward, push open the corresponding one-way baffle, and the cone nozzle B enters the cage assembly;

[0083] Open the electric damper;

[0084] Feed fish food through the bypass pipe A and the bypass pipe B, and lure the fish to push open the one-way cone mouth A, pass through the confluence pipe and the secondary pipe, and then enter the cage assembly;

[0085] As the fish enter the cage, they can only enter the cage assembly in one direction through the middle cone mouth C and the top cone mouth B;

[0086] During this period, with the help of camera observation, fish food is added through the side pipes A and B, or the electric baffle is closed. Fish that cannot swim out of the middle cone mouth C are defined as Class II healthy fish, fish that cannot swim out of the top cone mouth B are defined as Class II healthy fish, and fish that swim out of the top cone mouth B are defined as Class I healthy fish; fish that cannot enter the one-way cone mouth A are defined as Class III healthy fish, and are classified;

[0087] Retrieve the components entering the net cage to achieve classified fishing;

[0088] As for dead fish, they will enter the bottom of the box or float on the bottom of the box under the influence of ocean current;

[0089] Automatic collection through the upper cleaning cage assembly A and / or the lower cleaning cage assembly B;

[0090] During collection, the spiral disk is driven by rotation, so that dead fish or diseased fish enter the storage cavity, while fish that enter by mistake swim out through the middle notch.

[0091] In general, small cages facilitate pulling and moving. Matryoshka cages allow for a balanced distribution of large fish, with smaller fish swimming on the outside and smaller fish on the inside. Multiple cages can also be used to cultivate a variety of fish. Small cages are fast to move, while smaller fish are more vulnerable, allowing for quick replacement and forcing them to swim and grow. Direct and precise feeding is achieved through pipes. Counterweights allow for fixed positioning of the cages. In the event of a typhoon and a lack of time to move, the cages can be lowered to minimize losses. Large cages on the outside, smaller cages on the inside, reduce drag.

[0092] The pressure sensor can monitor dead and sick fish, reduce the spread of dead fish, ensure the freshness of meat and fish grading.

[0093] The staggered meshes allow the fry to be discharged, the pipes ensure that the fish swim in one direction as much as possible, achieving natural elimination, and the bionic structure avoids scratching or scaring the fish. The clever placement of the bait allows the fish to move forward automatically, and the telescopic rotating rod makes it easy to connect and disassemble, thus achieving separate breeding and grade screening.

[0094] The invention has beneficial effects and is described in conjunction with embodiments.

[0095] The invention has reasonable design, low cost, durability, safety and reliability, simple operation, time and labor saving, money saving, compact structure and convenient use. BRIEF DESCRIPTION OF THE DRAWINGS
