Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of breeding, in particular to a device for breeding carp in a pond. Background Art
[0002] The croaker, a member of the Cyprinidae family, belongs to the genus Cyprinidae. Commonly known as flower fish, peach blossom fish, and mountain croaker, it is widely distributed throughout my country's rivers and tributaries. It is an omnivorous, partially carnivorous freshwater fish, primarily found in mountain streams, especially in shallow, fast-flowing areas. Its meat is plump and highly valued. Because of its rapid growth, croaker fry can be grown and marketed within the same year, making it highly valuable for aquaculture development.
[0003] In the traditional breeding technology stage, farmers mainly rely on ponds to breed black carp, with low breeding density and relatively simple breeding technology.
[0004] With the advancement of science and technology, the aquaculture of black carp is gradually shifting towards modern farming. Farmers are beginning to adopt new technologies such as cage aquaculture and drum aquaculture in large water bodies such as reservoirs. This has increased stocking density, shortened the aquaculture cycle, and improved profitability. Despite some success, black carp aquaculture still faces several technical challenges, particularly in traditional pond aquaculture. Existing sewage systems often fail to effectively remove pollutants from the aquaculture water, leading to eutrophication and negatively impacting the growth and development of black carp. Due to the black carp's impatient nature, the aquaculture process can easily injure the fish, leading to disease and reduced survival rates. Traditional fishing methods often cause significant damage to the fish, triggering stress reactions and even death. Utility Model Content
[0005] In response to the above-mentioned deficiencies in the prior art, the utility model provides a pond culture device for black carp, which solves the problems of no sewage discharge, eutrophication of water quality, low feed utilization rate, damage and stress death caused by multiple fishing in the prior art black carp pond culture.
[0006] In order to achieve the above-mentioned purpose of the utility model, the technical solution adopted by the utility model is: a device for breeding a carp in a pond, comprising a grid-shaped walkway arranged in the pond, a breeding cage arranged below the walkway, a canvas slope arranged at the bottom of the pond for the breeding cage, a sewage collection ditch arranged in the middle of the canvas slope; an aerator is arranged on the outside of the walkway.
[0007] Furthermore, in the above-mentioned croaker pond breeding device, the inclination angle of the canvas slope to the horizontal plane is 15°.
[0008] Furthermore, in the above-mentioned carp pond breeding device, the width of the walkway is 50 cm.
[0009] Furthermore, the above-mentioned black carp pond breeding device has a breeding cage with a length of 5m, a width of 5m and a height of 2.5m, of which 2m is sunk into the pond and 0.5m is exposed above the water surface and hung on a grid-shaped walkway.
[0010] Furthermore, in the above-mentioned carp pond breeding device, the width of the sewage collection ditch is 3m.
[0011] The beneficial effects of this utility model are as follows: the device utilizes the three-dimensional space of the pond by combining a grid-shaped walkway with aquaculture cages. The walkway not only provides convenient inspection and operation access for management personnel, reducing human interference during the aquaculture process, but also centralizes aquaculture through the cages below, maximizing feeding efficiency and fishing convenience. Each aquaculture cage measures 5m in length, 5m in width, and 2.5m in height, respectively, facilitating daily management and feeding while accommodating an appropriate number of mullet schools, maintaining an appropriate aquaculture density and thus increasing the yield per unit of water.
[0012] The setting of the canvas slope and its 15° inclination angle help the sediments at the bottom of the pond (such as leftover bait, feces, etc.) to slide naturally into the sewage collection ditch for collection. The centralized sewage discharge effectively reduces the accumulation of pollutants in the water body and reduces the anaerobic environment at the bottom of the pond, thereby reducing the breeding of pathogens. The width of the sewage collection ditch reaches 3m, which is sufficient to accommodate and centrally treat these pollutants, facilitate subsequent cleaning and discharge, and greatly improve the water quality of the aquaculture water body. In addition, the aerators installed on the outside of the trail can continuously add dissolved oxygen to the water body, further promote water circulation, enhance self-purification ability, and provide a fresher and healthier living environment for the black carp, which is conducive to its rapid growth and immunity improvement.
[0013] This device significantly improves the economic benefits of aquaculture farms by increasing aquaculture efficiency, reducing disease incidence, and lowering water quality management costs through improved water quality. On the one hand, the rational use of aquaculture space and the continuous optimization of water quality have shortened the growth cycle of the black carp, improving both survival rate and quality, directly increasing aquaculture output and commercial value. On the other hand, the design of the sewage collection ditch simplifies the pond cleaning process, reduces the use of chemical disinfectants, and reduces environmental remediation costs. Furthermore, the precise placement of aerators avoids energy waste and ensures energy efficiency during the aquaculture process. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The specific implementation methods of the present invention are described below to facilitate understanding of the present invention by those skilled in the art. However, it should be clear that the present invention is not limited to the scope of the specific implementation methods. For those skilled in the art, as long as various changes are within the spirit and scope of the present invention as defined and determined by the appended claims, these changes are obvious, and all utility model creations using the concept of the present invention are protected.
[0018] like Figure 1 As shown, this embodiment provides a croaker pond aquaculture device, comprising a grid-shaped walkway 1 disposed within the pond, aquaculture cages 2 disposed below walkway 1, and a canvas slope 3 disposed at the bottom of the pond above cages 2, with an inclination angle of 15° to the horizontal. A sewage collection ditch 4 is disposed in the middle of canvas slope 3, with a width of 3 meters. An aerator 5 is disposed outside walkway 1.
[0019] This device is installed in a pond with sufficient water supply and convenient water inlet and outlet. A small number of silver carp and bighead carp are raised in the pond to purify the water quality, improve water utilization, and increase output value. The pond must be away from pollution sources to ensure that the water quality meets the growth requirements of the black carp. In this example, the pond water depth is set to 3.0 meters, which is conducive to the growth and activities of the black carp, maintains water stability, and reduces the impact of temperature changes on the fish. Before the pond is put into use, necessary renovations and cleaning work must be carried out. Remove silt and weeds from the bottom of the pond to prevent them from decomposing and producing harmful substances that affect the water quality. At the same time, reinforce the embankments around the pond to ensure the stability and safety of the water during the breeding process.
[0020] The grid-shaped walkway 1 in this example is made of a high-strength, corrosion-resistant plastic material, namely a plastic fish raft. This material is not only light and durable, but also easy to clean and maintain, making it very suitable for aquaculture.
[0021] Plastic fishing rafts are laid in the middle of the pond, forming multiple grid-like walkways 1. The width of the walkways 1 is set at 50 cm, which is convenient for personnel to walk and manage without taking up too much pond space. The walkways 1 are appropriately spaced to facilitate smooth water flow.
[0022] The aquaculture cage 2 is 5 meters long, 5 meters wide, and 2.5 meters high, made of high-strength, age-resistant nylon mesh. A canvas slope 3 is installed at the bottom of the cage, with a 15° angle to the horizontal. This design facilitates the natural sedimentation and collection of waste, such as leftover bait and feces.
[0023] The aquaculture cage 2 is fixed to the bottom of the plastic fish raft and secured by ropes or fixing frames to ensure that the cage will not shake or shift under the influence of wind, waves or currents, thereby providing a stable growth environment for the black carp.
[0024] A canvas slope 3 is laid at the bottom of the cage to not only facilitate the sedimentation of dirt but also prevent excessive mud accumulation at the bottom of the cage, which could affect water quality. A 3-meter-wide drainage ditch 4 is located in the middle of the canvas slope 3. This ditch collects dirt that accumulates on the slope, and regular cleaning helps maintain a clean environment within the cage.
[0025] Mesh is placed on top of the aquaculture cages 2 to prevent bird predation. Nanoporous aeration equipment is installed between the cages, using microporous aeration technology to dissolve oxygen from the air into the water, increasing the dissolved oxygen content. A 1.5kW impeller aerator 5 and a 1.5kW waterwheel aerator 5 are placed around the cages. The impeller aerator 5 stirs the water with rotating blades, increasing dissolved oxygen. The waterwheel aerator 5 utilizes the principle of water circulation to bring oxygen-rich surface water to the bottom layer, achieving a balanced dissolved oxygen content between the upper and lower layers of the water.
[0026] A floating feeding basket made of 50mm diameter PVC pipe is placed in each net cage. The square size of the feeding basket is 1.4 meters x 1.4 meters. The design of the feeding basket allows the feed to be evenly distributed in the water, reducing feed waste and pollution. In this embodiment, the feed mainly contains fish meal, chicken meal, soybean meal and rapeseed meal as protein sources, and soybean oil, fish oil and soy lecithin as fat sources. During the rearing period, the fish are fed a daily feed of 4% of their body weight, and the feed is manually sprinkled at a fixed time and place for feeding. During the rearing period, the fish are fed twice a day to their fullness, and each feeding is carried out in small amounts and multiple times. Each feeding cycle is 4 to 5 times, with an interval of 10 minutes between each round. The feeding time is about 1 hour, until there is almost no residual feed in the feeding basket and no feed overflows from the outside of the net cage. Feeding should also be appropriately adjusted according to changes in weather, water temperature and food intake.
