Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, and particularly relates to a movable breeding device for increasing the parasitic amount of freshwater shellfish and a using method thereof. Background Art

[0002] By means of filter feeding, mussels can effectively remove planktonic algae, suspended particles in water, organic debris and bacteria in the bottom sediment, and are natural "cleaners" of water bodies. In the benthic biological community of freshwater ecosystems, mussels are an important component, but the total amount of their resources has decreased sharply, and their survival is facing a severe test. Artificially breeding shellfish resources and supplementing them into nature to restore the natural ecosystem is a rapid and effective method.

[0003] During the large-scale breeding process of river mussels, parasitism is a key step, and ensuring the parasitic quantity of host fish is the core link to increase the shellfish yield. During the large-scale breeding process, some host fish are irritable and love to jump, splashing the water containing glochidia out of the container; some host fish are gentle and not easy to move, and the glochidia are easy to sink to the bottom of the basin, resulting in poor parasitism effects. These will all affect the parasitic amount of host fish, and thus affect the breeding effect of river mussels. The currently commonly used parasitism method is to put the water containing glochidia into a basin and then put the host fish to complete the parasitism work. The host fish swims in the basin and breathes deeply to adsorb the glochidia on the gills. However, the conventional basin has a relatively low height, and the water containing glochidia will be splashed out by the host fish during the parasitism process. At the same time, some host fish may escape from the basin; for some host fish that like to be quiet, it is also necessary to manually shake the periphery of the basin to make the host fish active. During the large-scale breeding process, a large area of the site is required to place the breeding device; at the same time, shaking the basin wastes a lot of labor, and the shaking is uneven, which is likely to cause fish disturbance and glochidia overflow. After parasitism, it still needs to be manually transported to the cultivation pond, causing secondary disturbance, and the host fish is prone to death. Generally, there are still a small number of glochidia left in the basin after the first parasitism. Secondary utilization can effectively increase the parasitic amount and improve the breeding efficiency.

[0004] The traditional parasitism method not only consumes a large amount of glochidia and host fish, increases the breeding cost, and consumes a lot of manpower and material resources, but also cannot guarantee a good parasitism effect. Therefore, it is very important to design a breeding device with low cost, easy management and capable of effectively increasing the parasitic amount. Summary of the Invention

[0005] The purpose of the present invention is to provide a movable breeding device for increasing the parasitic amount of freshwater shellfish, and solve the problem that the traditional parasitism method not only consumes a large amount of glochidia and host fish, increases the breeding cost, consumes a lot of manpower and material resources, but also cannot guarantee a good parasitism effect.

[0006] The technical solution adopted by the present invention to solve its technical problems is: an oscillating breeding device for improving the parasitism rate of freshwater shellfish, including a plurality of parasitic barrel structures for the completion of parasitism of glochidium larvae and host fish, an oscillation system structure arranged at the lower part of the parasitic barrel structure, and a spray water circulation system arranged at the upper part of the parasitic barrel structure. The oscillation system structure includes a motor, an oscillation support frame, and a barrel body connection platform. The parasitic barrel structure includes a main host breeding barrel and a secondary host breeding barrel. The lower ends of the main host breeding barrel and the secondary host breeding barrel are respectively connected to the corresponding oscillation system structures. A main drain pipe body is arranged on one side of the main host breeding barrel, and a leakage drain pipe is arranged at the bottom of the main host breeding barrel; it is connected to the secondary host breeding barrel through the leakage drain pipe, and the outside of the main host breeding barrel is connected to the spray water circulation system. An access port connected to the leakage drain pipe is arranged on one side of the secondary host breeding barrel, and a secondary drain pipe body is arranged on the other side of the secondary host breeding barrel.

[0007] The spray system includes a water storage barrel, a connecting pipe, and a movable nozzle.

[0008] A method for using an oscillating small breeding device for improving the parasitism rate of freshwater shellfish. During the parasitism process: spray around the main host breeding barrel every 50 seconds, spray the glochidium larvae attached to the wall of the main host breeding barrel into the water to increase the number of host fish parasitized, spray for a total of 10s, and the water consumption is about 120ml. Since the parasitism time of the host fish is generally about 5 minutes, spray 5 times in a single parasitism process, consuming about 600ml of water. After the parasitism work is completed, the water containing glochidium larvae enters the secondary host breeding barrel through the leakage drain pipe below, and the host fish directly flows into the cultivation pond through the main drain pipe body on the side of the main host breeding barrel. Then, close the leakage drain pipe and the main drain pipe body. After the glochidium larvae in the secondary host breeding barrel settle to the bottom, drain the water without glochidium larvae on the upper layer of the main host breeding barrel from the side pipeline; this pipeline is about 1cm away from the bottom of the main host breeding barrel, and a small amount of water containing glochidium larvae can be retained. After adding water to a certain amount by the spray system on the upper part of the secondary host breeding barrel, add a small amount of host fish again, and repeat the above parasitism work to improve the utilization rate of glochidium larvae; because the parasitism effect of the glochidium larvae in the second time is relatively poor, the required parasitism time also needs to be appropriately increased.

[0009] The beneficial effects of the present invention: This device has a low manufacturing cost and can be reused; it can be automatically cleaned to ensure that the glochidium larvae can always be suspended in the water, reducing the waste of glochidium larvae and host fish; this device is a movable small device, which can be operated by a single person, reducing the labor cost. At the same time, the device can be placed beside the cultivation pond, and the host fish can directly enter the pond after parasitism, reducing manual transportation and facilitating movement and breeding. At the same time, in the face of large-scale breeding, the devices can also be connected together in an assembled manner to complete the breeding work in batches.
