Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, and in particular to an integrated fry and water flower cultivation system. Background Art

[0002] In aquaculture, seedlings are one of the key factors, and the fry and splash cultivation stage is of utmost importance. Fry and splash refer to young fish that have just hatched from fish eggs, also known as "splashes" or "fish flowers." These young fish are usually 7-8 mm in length, and in some areas refer to fry from hatching to 1 inch (about 3.33 cm) in length. Firstly, the fry and splash cultivation stage is a basic link in aquaculture. Fry and splash cultivation is the starting link in aquaculture and plays a vital role in the success of the entire breeding cycle. It provides a high-quality seedling foundation for subsequent breeding and directly affects the cost and benefits of breeding. Secondly, the fry and splash cultivation stage is also the key to germplasm assurance. Through fry and splash cultivation, high-quality and healthy seedlings can be selected, thereby improving the genetic quality and growth performance of the entire breeding population, which is of great significance for enhancing the market competitiveness of breeding products.

[0003] Currently, the industry's fish fry rearing model can be roughly divided into two models: traditional pond rearing and indoor or factory rearing. Although the traditional pond model has a long history, it has the following disadvantages: difficult water quality and piping, limited natural bait quantity and variety, risks of disease and predators, high technical requirements, and seasonal and geographical restrictions. Factory cultivation can be roughly divided into flow water (water exchange) cultivation mode and circulating water cultivation mode. In the flow water (water exchange) cultivation mode, the water body cannot be circulated, the water exchange rate is high, the system heating energy consumption is high, and the water environment is unstable; the existing circulating water flower cultivation system is basically a standard circulating water aquaculture system, the system unit size is large, and the process is complex; for the flower cultivation stage, the water flow rate should not be too large, and the traditional model of circulating water flower cultivation system, the exchange of water in the breeding pond and the water in the water treatment area is generally carried out through the inlet / outlet pipe, which will cause excessive local water flow and affect the development of the flowers; at the same time, in order to prevent the flowers from escaping, anti-escape nets with very small mesh are often used at the inlet / outlet pipes. Due to the small area of ​​the anti-escape net, there is a serious blockage problem, and cleaning is also very troublesome, which greatly affects the overall use effect of the system.

[0004] The cultivation of water fry greatly affects the subsequent results of large-scale fry coarsening and adult fish breeding. At present, many farmers engaged in seedling production focus on the stage of large-scale fry cultivation. They mainly purchase standard seedlings that are centrally cultivated by others for coarsening. There are fewer farmers who directly purchase water fry for cultivation. This model has lower economic benefits than the model of purchasing water fry for cultivation and then coarsening. At the same time, it is difficult to control the quality of purchased seedlings. The investment in coarsening directly purchased seedlings is greater. Once problems arise, the economic losses are greater, and it is more difficult to control the breeding plan. The above content shows a tendency to be unfriendly to farmers who specialize in coarsening breeding.

[0005] In the above context, building an integrated fish fry and water splash cultivation system meets the development needs of the aquaculture industry. Utility Model Content

[0006] In order to solve the above-mentioned deficiencies in the prior art, the utility model provides an integrated fry water splash cultivation system.

The water treatment pond is erected in the center of the breeding pond. The water treatment pond includes a bottom plate, side retaining walls and a top guide plate arranged from bottom to top. The lower and upper parts of the side retaining walls are respectively provided with water holes, and the water holes are covered with anti-escape nets; the outer periphery of the top guide plate is connected to the top of the side retaining wall, and the middle part of the top guide plate is in an inverted cone shape; an aeration plate is provided above the bottom plate of the water treatment pond.

[0009] Furthermore, a sewage outlet is provided in the center of the bottom of the breeding pond, and the lower part of the sewage outlet is connected to the bottom drainage pipe.

[0010] Preferably, a filter is installed at the sewage outlet.

[0011] Furthermore, the bottom of the breeding pond is in an inverted cone shape, and the slope of the bottom of the breeding pond is 10%-30%.

[0012] Preferably, the slope of the bottom of the culture pond is 20%.

[0018] The beneficial effects of the utility model are:

[0019] The utility model provides an integrated fish fry water flower cultivation system, in which a water treatment tank is located in the center of a breeding pond, and an annular water hole is provided on the upper and lower parts of the side retaining wall of the water treatment tank. A top guide plate is provided on the top, and aeration is provided to the water treatment tank through an aeration plate, which can drive water to flow from bottom to top, and divert water to the surrounding areas through the top guide plate, and flow to the breeding pond through the water hole. The water in the breeding pond flows back to the water treatment tank through the water hole at the bottom of the water treatment tank, thus realizing water circulation treatment. The water circulation power relies on the air push + diversion method, and the system operation is simple. The power of a single system is low, and it only needs aeration to operate immediately under the operating conditions of suitable water temperature. The water hole is arranged in an annular shape and covered with an anti-escape net, which greatly increases the cross-sectional area of ​​the water exchange mesh. Under the premise of ensuring the water exchange volume, it greatly reduces the water flow rate and solves the problem of anti-escape net clogging.

[0021] This integrated fish fry aquaculture system utilizes a factory-scale circulating water concept, resulting in an integrated and miniaturized system for easy transportation, installation, and mobility. The system boasts low construction costs and can be operated independently or in combination, increasing system flexibility and applicability. It occupies a small footprint, achieves high aquaculture density, and recycles aquaculture water, requiring less than 5% daily water replenishment, conserving water resources. Water quality indicators such as ammonia nitrogen and salinity are safe, stable, and controllable, improving fry quality and survival rates during the aquaculture phase.

[0022] The utility model has strong compatibility and can adjust the volume ratio of the water treatment pool and the breeding pool to cultivate large-sized fish fry of various varieties. BRIEF DESCRIPTION OF THE DRAWINGS
