Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, and in particular to a full-cycle frog and lotus root compound circulation comprehensive breeding method. Background Art

[0002] With the rapid development of fisheries, aquaculture practitioners usually increase the density of aquaculture per unit water body in order to increase aquaculture output and obtain better aquaculture benefits. However, the high-density intensive aquaculture model has disadvantages such as environmental pollution, uncontrollable water environment, and difficulty in preventing and controlling fish diseases. In frog farming, the trend is also developing towards high-density intensive aquaculture, especially in the intensive breeding model of bullfrogs, wood frogs and other frogs, where the water environment is seriously polluted. In addition, when diseases break out, farmers usually invest a lot of fish medicine to ensure the safety of the breeding objects, and the quality of frogs under high-density breeding conditions also needs to be improved urgently. In adult frog farming, there are also disadvantages such as seed loss and pathogen invasion during seed transportation, and an integrated breeding model integrating seedling and breeding throughout the entire cycle needs to be developed. In addition, when frogs are put on the market in large quantities, there is a problem of oversupply, resulting in price reduction and reduced profits. Therefore, the improvement and optimization of the water environment has become a problem that currently hinders the healthy development of the frog farming industry. The high-density full-cycle healthy ecological breeding model is also the key development direction of frogs and the entire aquaculture industry in the future.

[0003] At present, many public documents related to frog breeding and lotus root planting can be consulted, but there is little information on breeding models that combine the two. The invention patent with announcement number CN201410712127.6 discloses a high-efficiency circular breeding method for bullfrogs, which only involves a breeding method of bullfrogs in lotus root ponds under the traditional breeding model, and does not extend to the layout of the temperature-controlled nursery workshop on the bank, early seedling supply, and early sale of adult frogs.

[0004] An analysis and comparison of existing public data shows that in the process of frog breeding, drugs are used to reduce the threat of diseases. However, excessive use of drugs will lead to harmfulness of aquaculture effluent, and the direct discharge of aquaculture effluent is also a waste. Summary of the invention

[0005] The object of the present invention is to provide a full-cycle frog and lotus root compound cycle integrated breeding method. Through the effective combination of a pond bank temperature-controlled seedling nursery workshop and a frog and lotus root co-cultivation pond, full-cycle frog breeding can be achieved, seedlings and adult frogs can be sold in staggered peaks in advance, the problems of tail water treatment in frog breeding and fertilization in lotus root planting can be solved, the comprehensive output of lotus root co-cultivation can be increased, and the economic benefits can be improved, so as to solve the problems raised in the above-mentioned background technology.

[0031] Step 1. Site selection: The breeding site and its surrounding areas should meet the objective geographical conditions such as flat terrain, abundant water resources, convenient irrigation and drainage, fertile soil, sufficient power supply, good water quality without pollution, no flooding, convenient water intake and transportation. The site should be selected from paddy fields with flat terrain that can be used for fence reconstruction. The area of ​​a single paddy field should be ≥ 2 mu, and the surrounding area of ​​the field should also have 1-2 mu of flat land that can be used to build a temperature-controlled seedling workshop;

[0032] Step 2, site transformation: dig a 0.5-1m deep and 1.5-2m wide ditch around the paddy field as the main frame area of ​​the suspension mat and the feeding place. Set up an escape-proof fence around the paddy field. The bottom of the fence is inserted into the soil 20-30cm deep and 1.2-1.5m above the ground surface. The inlet and outlet need to be covered with gauze. The paddy field adult frog breeding area is covered with a sky net to avoid predation by natural enemies such as birds. A special suspended mat with holes for frogs is arranged in the paddy field, covering 10-20% of the overall area. An insect attractant is arranged 2-3m away from the ridge, about 0.5m above the water surface;

[0033] Step 3, construction of temperature-controlled nursery workshop: A rectangular breeding pond with a length of 4-6m, a width of 1.5-3m, a height of 1-1.2m, and a cone bottom depth of 15-20cm is built on the selected land of the temperature-controlled nursery workshop. Well water is preferred as the water source for the workshop.
