Embodiment 1

[0029] In mid-March 2016, in order to verify the beneficial effects of the present invention, the research team carried out relevant research practices in the pollution-free agricultural product production base in Linghu Town, Huzhou City, Zhejiang Province. The specific methods are as follows.

[0030] S1. Breeding pond selection, cleaning pond disinfection and basal fertilizer application: select a pond with an area of ​​12 mu with sufficient water source and water quality that meets the fishery water quality standard as the water carp breeding pond; in mid-March, use the quicklime dry pond method to clear the pond for disinfection, every 666.7 m 2 Use 65kg of quicklime; the specific method of clearing the pond is: first drain the pond water, dig a few small pools around the pond, let the water flow in, then put the quicklime into the melt, and immediately sprinkle the whole pond without waiting for cooling; after drying the pond for 10 days, every 666.7m 2 Apply 3400 kg of...

Embodiment 2

[0036] In order to verify the effect of the fish fry physique improvement solution in the pre-stocking step in the inventive route, the research team conducted relevant comparative experiments in the same production base mentioned above. The specific method is as follows.

[0037] The present invention: get 150 tails of water carp fry of the same specification kind in embodiment 1, adopt the method in embodiment 1, put in a suitable place to breed the fry after pre-stocking treatment in the fish pond, observe and record fry survival rate and health degree thereof, the result As in Table 1.

[0038] Routine treatment: get 150 water silver carp fry of the same specification kind in embodiment 1, after immersing 10min with 3% sodium chloride solution, put in a suitable place to breed in the fish pond, observe and record fry survival rate and its robustness, the results are shown in Table 1 .

[0039]

[0040] From table 1, we can find out that adopting technical route of the ...

Embodiment 3

[0042] In order to verify the beneficial effect of the basal manure applied in the route of the present invention, the research team adopted the same method steps as in Example 1 except that the basal manure was replaced by pig manure, and 80m pigs were raised on the same farm 2 The water carp was harvested and the yield was measured, and the results are shown in Table 2.

Abstract

The invention discloses an environment-friendly, low-cost and high-yield hypophthalmichthys molitrix aquaculture method. The method includes steps: S1, aquaculture pond selection, pond clearing and disinfection and base fertilizer applying; S2, water chestnut planting, loach stocking and management; S3, hypophthalmichthys molitrix fry disinfection and pre-releasing; S4, fry stocking and feeding management; S5, water chestnut and adult fish harvesting. By interplanting of the water chestnuts, hypophthalmichthys molitrix disease damages can be prevented under the allelopathic effect of the waterchestnuts, so that agent input is reduced; by applying of a base fertilizer rich in various organics, soil and water eutrophication level is raised, growth of plankton and algae in water is benefited, and natural food sources are increased for hypophthalmichthys molitrix; by spraying of fry physique improving liquid in the stage of hypophthalmichthys molitrix pre-releasing, the fry survival rateis guaranteed, fry strengthening is realized, and a foundation is laid for high yield and yield increasing of hypophthalmichthys molitrix; by matching of feeds suitable for different growth stages ofhypophthalmichthys molitrix, giving full play to functions of active substances in the feeds is realized, hypophthalmichthys molitrix growth and maturity can be accelerated, and hypophthalmichthys molitrix yield increasing and quality improvement are realized.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a low-cost, high-yield and environment-friendly breeding method for water carp. Background technique [0002] Water carp ( Hypophthalmichthys molitrix ) is also known as silver carp, jumping carp, silver carp, side fish, etc., belongs to Cyprinidae, Cyprinidae, and is one of the famous "Four Great Fishes". Mercury carp is a large freshwater fish with a flat body, a large head, no beards, small eyes, a wide mouth, and a silver-white body. It is widely distributed in various regions of my country and is the main freshwater cultured fish in my country. The water carp raised in artificial reservoirs, ponds and lakes grows fast, has a short growth cycle, less disease, and high yield. The average weight is 1-4kg. Feeding value. Silver carp is a pelagic fish. In spring, summer and autumn, most of the time it swims in the upper and middle layers of waters for food, and dives into deep water...
