Description

Three-dimensional ecological breeding cage for abalone and sea cucumber

technical field

The invention relates to the field of aquaculture devices, in particular to a three-dimensional ecological culture cage for abalone and sea cucumber.

Background technique

As we all know, the current main methods of sea cucumber and abalone farming include land factory farming, pond culture, intertidal zone cofferdam culture, seabed catapulting and reef culture, etc., which not only require huge investment, but also artificially change the growth environment of sea cucumber and abalone. The rate is low, the risk is high, and it will have a certain impact on the natural environment. At the same time, in the breeding process, sea cucumbers and abalones are cultured separately or mixed with abalones. The former is convenient for feeding and harvesting, but the waste of bait is relatively large and the cost is high; the latter breeds abalones and sea cucumbers on the same plane. It is conducive to the full utilization of bait, but abalone and sea cucumber live together, and because their habits are not completely the same, they will have adverse effects on each other, thereby affecting the growth of abalone and sea cucumber, and are also unfavorable for harvesting.

Contents of the invention

In order to overcome the deficiencies of the prior art, the present invention provides a three-dimensional ecological breeding net cage for abalone and sea cucumber, which has simple structure, strong wind and wave resistance, low production cost, and convenient production and operation, which can enable layered cultivation of abalone and sea cucumber in the natural environment , not only is conducive to the full utilization of bait, reducing emissions, but also can turn waste into treasure, maximizing the production profit margin.

The technical solution adopted by the present invention to solve the technical problem is: a three-dimensional ecological breeding net cage for abalone and sea cucumber, which is provided with a base and net clothing, and is characterized in that the base is composed of an upper sinking tube, a sinking tube and a support tube, and the upper The immersed tube and the sinking tube are circular or polygonal. There is an upper support frame in the middle of the upper sinking tube, a lower support frame in the middle of the sinking tube, and vertical or oblique support between the upper sinking tube and the sinking tube. The bottom of the net is fixedly connected to the upper sinking tube, the middle of the net is provided with a support ring, the middle of the support ring is provided with a support frame, the support ring is provided with a mesh, and the periphery of the mesh is connected with the net. Fixed connection, the net will empty the space in the net

The space is divided into upper and lower layers. There are seedling holes on the mesh. The upper part of the net is fixedly connected to the floating tube. The floating tube is circular or polygonal. The opening of the net is set in the middle of the floating tube. There are brackets to support the net clothing, the opening of the net clothing is fixedly connected to the net cover, and the top of the net cover is provided with a bait feeding port.

The present invention can also be realized by the following measures: the lower layer of the net clothing is provided with an observation port. A buoy is arranged on the floating pipe. A support leg is fixed below the sinking tube. A support rod is connected between the support ring and the upper immersed tube. The net is interspersed with reinforcing ropes.

The invention has the beneficial effects of simple structure, strong wind and wave resistance, low production cost, convenient production and operation, enabling layered cultivation of abalone and sea cucumber in the natural environment, which is not only beneficial to the full utilization of bait, reducing emissions, but also variable Turning waste into treasure maximizes production profitability.

Detailed ways

In Fig. 1, the present invention is provided with base and net clothing 14, and base is made of sinking tube 12, sinking tube 16 and support tube 13, and sinking tube 12, sinking tube 16 are circular or polygonal, and sinking tube 12 is provided with an upper bracket 11, and the middle of the sinking tube 16 is provided with a lower bracket 15. Between the upper sinking tube 12 and the sinking tube 16, a support tube 13 is provided vertically or obliquely, and a netting is provided on the base. 14. The bottom of the net 14 is fixedly connected to the upper sinking tube 12, the middle part of the net 14 is provided with a support ring 9, the middle of the support ring 9 is provided with a support frame 8, and the support ring 9 is provided with a mesh 10, and the periphery of the mesh 10 is connected to the The netting 14 is fixedly connected, and the space in the netting 14 is divided into upper and lower layers by the mesh 10. The mesh 10 is provided with 2-6 seedling throwing holes 7, and the top of the netting 14 is fixedly connected to the floating pipe 5 and the floating pipe 5. Be circular or polygonal, the opening 3 of net clothing 14 is located at the middle part of floating tube 5, is provided with 4 supports 4 (or reinforcing rope) between opening 3 and floating tube 5 to support net clothing 14, the net clothing 14 The opening 3 places are fixedly connected to the net cover 2, and the top of the net cover 2 is provided with a bait feeding port 1. There are several reinforcing ropes 6 interspersed on the netting 14, and the reinforcing ropes 6 play the role of reinforcing ribs, which can prevent the netting 14 from being torn due to excessive sea currents, and a supporting rod 17 is connected between the supporting ring 9 and the upper sinking tube 12 , when cultivating abalone on the net sheet 10 of net clothing 14 upper floors, support bar 17 can play a supporting role, prevents net sheet 10 from being pressed to net clothing 14 bottoms because of the weight of abalone.

When the present invention is in use, the sea cucumber attachment base is placed in the bottom layer of the net clothing 14 through the seedling throwing hole 7 on the mesh 10, and a certain number of sea cucumbers of a certain specification are put in, the abalone attachment base is placed on the mesh 10, and placed Put in a certain amount of abalone with a certain specification, and then put in bait such as kelp from the bait feeding port 1, and use a ship-mounted crane to sink the whole cage into the shallow seabed at a depth of 5-10 meters. The base sinks on the seabed due to gravity, and the floating tube 5 floats upwards under the effect of buoyancy, and also can be tied with buoy on the floating tube 5, so that the net clothing 14 is stretched out in the seawater to form a box body, this net cage is relatively strong in wind and wave resistance, so abalone in the net clothing 14 The upper layer of the sea cucumber grows, and the lower layer in the sea cucumber net 14 grows. The sea cucumber mainly feeds on the residual bait and excrement of the abalone, which is not only conducive to the full utilization of the bait and reduces emissions, but also turns waste into treasure, and the residual bait and excrement of the abalone Converted into high-quality protein of sea cucumbers to maximize production profit margins. The bait feeding port 1 can be tied to the raft or floating rope on the sea surface. According to the feeding situation of the abalone, the kelp is fed from the bait feeding port 1 at intervals of a certain time. Cages are pulled out or harvested by divers. Net clothing 14 lower floors of the present invention can also be provided with observation port. A support leg may also be fixed below the sinking tube 16 .
