Problems solved by technology

[0008] The purpose of the present invention is to solve the problem of poor water quality when silver carp and bighead carp are cultured in large water surfaces such as lakes or reservoirs, which is not suitable for the growth of bighead carp, and the growth rate of fish is slow and the yield is low, resulting in low income of fishermen and poor economic benefits. , to provide a low-cost, healthy and efficient method for farming bighead carp in large water surfaces

Embodiment 1

[0033] see figure 1 , figure 2 , the present embodiment takes the method of cultivating silver carp and bighead carp in a small reservoir of 1350 mu on the open space near the water source as an example, to explain in detail the specific cultivation method of the present invention:

[0034] (1) Excavate a 1,350-mu reservoir 1 on open land close to the water source, build a 100-mu plankton cultivation pool 2 that is 1.5 meters higher than the reservoir upstream, and build 4 holes higher than the plankton in the upper reaches of the plankton cultivation pool 150 cubic meters of chicken manure fermentation tank 3 with 1 meter of cultivation pool;

[0035] (2) Build a water tower 4 between the chicken manure fermentation tank, the plankton cultivation tank, the reservoir, and the water source. A water pump 5 is arranged in the water tower. The fermentation tank, the plankton cultivation tank and the reservoir are connected, and a drain pipe 7 is arranged between each chicken ma...

Embodiment 2

[0045] see image 3 , the present embodiment takes the method of cultivating silver carp and bighead carp in small lakes with more than 1700 mu of upstream supply rivers as an example to explain the specific culture method of the present invention.

[0046] (1) Build a retaining dam 17 at the water inlet of the upstream river 16 of the small lake 15 with an area of ​​more than 1,700 mu to raise the water level of the upstream river by 1.5 meters, and set up a sluice 19 at the outlet of the downstream effluent river 18. A blockage 13 is set on the side of the lake, which is convenient for water level management in the lake and prevents fish from escaping from the downstream. A plankton cultivation pond 2 of 120 acres higher than the lake 2 meters is built at the upstream river and adjacent to the lake. Build 4 chicken manure fermentation tanks 3 of 200 cubic meters higher than the plankton cultivation pond 1.5 meters in the upper reaches of the pond; step-type outlet culverts a...

Abstract

The invention relates to the field of aquaculture, in particular to a large-water-surface low-cost healthy high-efficiency bighead cultivating method. Facilities of a plankton cultivating tank, a chicken manure fermenting tank and a water tower are built on a water reservoir or a lake more than 500 acres. Chicken manure slurry is injected into the plankton cultivating tank to cultivate plankton suitable for growth of bigheads, so that the stocking proportion of the bigheads in the water reservoir or the lake can be increased to 80%. Aquatic plant products of cane shoots and arrowheads are utilized to consume humus in the plankton cultivating tank and adjust water quality and water temperature in the plankton cultivating tank, so that the possibility of diseases to fish in the water reservoir or the lake is fundamentally avoided. The method uses the chicken manure fermenting tank and the plankton cultivating tank to circularly cultivate plankton to provide good-quality feeds for fish in the water reservoir or the lake. Thus, the purposes of cultivating the bigheads with higher economical value and multiplying the yield of the fish in the water reservoir or the lake are achieved, the production cost is greatly reduced, and good popularization value is achieved.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a low-cost, healthy and high-efficiency method for cultivating bighead carp in a large water surface. Background technique [0002] At present, the traditional aquaculture in large water surfaces such as natural lakes or reservoirs in my country is mainly based on polyculture of silver carp and bighead carp. The ratio of silver carp and bighead carp is generally 8:2 or 7:3. Feed mainly chemical fertilizers or manure. Under this farming model, after a year of farming, the weight of silver carp is 2 to 3 catties, and the weight of bighead carp is 3 to 4 catties, reaching the growth bottleneck. It is difficult to continue to gain weight and can only be marketed. However, the price of small-sized silver carp and bighead carp is cheaper than that of large-sized silver carp and bighead carp, resulting in limited income for fishermen and low economic benefits. After analysis, this farming model...
