Problems solved by technology

However, the high-density sowing of scallop seedlings has caused a great burden on the original ecosystem of the cultured sea area, especially the various microalgae used as food for scallops. Once climate change or other environmental changes occur, it is very easy to cause related algae populations in the cultured sea area The number has dropped sharply, further causing the continuous starvation stress of farmed scallops
In recent years, there have been reports of large-scale disappearance or migration of scallops from related companies that have continued to sow and multiply at the bottom, which has brought huge losses to the local aquaculture industry.

Embodiment 1

[0038] A migratory seabed culture device, such as figure 1 As shown, it includes a cube frame group 1, a boat base 2, a rope 3 and a positioning float 4. Balls 4 are connected.

[0039] The cube frame group 1 is composed of more than one cube frame, such as figure 2 As shown, the cube frame includes a common plate frame 5, a dodge door frame 6 and a connecting rod 7, the plate frame is a frame structure hollowed out in the middle, and the plate frame material is selected from a seawater corrosion-resistant non-metallic material with a certain strength ( Such as hard plastic resistant to seawater corrosion), the size of the plate and frame can be adjusted according to the breeding process.

[0040] Such as image 3 As shown, frame insertion holes 8 are provided at four corners of one side of the common frame 5 .

[0041] Such as Figure 4 As shown in (a), the upper edge of the hollowed-out part of the front of the movable door panel frame 6 is provided with a rotating sha...

Embodiment 2

[0050] The operation process of the above-mentioned migration type seabed culture device is as follows:

[0051] When there is no seawater flow, the rotating plate 14 hangs down naturally; when the seawater flows, causing the rotating plate 14 to open, as Figure 8 As shown in (a), downward seawater flow is provided, and the seawater flow that is rich in algae is continuously supplied for the cultivation cabin body 17; When seawater flows, when causing rotating plate 14 to close, as Figure 8 As shown in (b), provide upward and downward seawater flow, while continuously supplying the seawater flow rich in seaweed for the culture cabin 17, generate a driving force in the direction of seawater flow, and provide power for the migration of the migratory seabed culture device .

[0052] Such as figure 1 As shown, the cube frame group 1 is installed on the boat base 2 to form a culture unit 21. The culture unit 21 can be fixed by an anchor 20, or the migration speed can be reduced...

Abstract

The invention discloses a migration-type undersea breeding device and an operation process thereof. The device comprises a cubic frame group, a boat-type base, a rope and a positioning floater. The cubic frame group is arranged on the boat-type base. The boat-type base is connected with the positioning floater through the rope. The cubic frame group comprises more than one cubic frame. The migration-type undersea breeding device has the advantages that the device has a simple structure and a low cost, seawater flows are taken as driving forces, directional migration of an undersea farm is achieved, ecological burdens on the same sea area are avoided, and abnormal changes in a certain seawater temperature can be avoided; according to the flow field effect of artificial fish reefs, downwardseawater flows are provided, so that seaweed-rich seawater flows are continuously supplied to the undersea farm; according to the biological effect of the artificial fish reefs, a multilayered marinefarm is formed.

Description

technical field [0001] The invention belongs to the field of marine aquaculture, and in particular relates to a migratory seabed aquaculture device and an operating process thereof. Background technique [0002] Bottom sowing and multiplication of shellfish refers to the production activities of putting artificial seedlings or semi-artificial seedlings of shellfish on the substrate of waters with suitable environment, and cultivating them through natural growth. Bottom-seeding multiplication mode has many advantages such as the breeding site is located on the seabed where there is no temperature and salinity, the environment is less affected by wind and waves, the habitat water temperature is low and the change is small, and it is suitable for cold-water biological breeding. For example, the scallops multiplied by bottom-seeding are It grows naturally on the seabed at a water depth of about 30 meters, and has become an important economically cultivated shellfish along the co...
