Embodiment 1

[0025] A kind of breeding method utilizing ecological floating bed technique pond to culture perch-crucian carp, comprises following concrete steps:

[0026] (1) Pond settings:

[0027] The water depth of the pond is 1.8m, the bottom of the pond is 20cm deep, and it is leeward to the sun. It is rectangular and has a slope ratio of 1:1.5. Aeration and aeration machines are installed at both corners of the pond. After the whole pool is sprayed to completely kill potential pathogens and harmful organisms, etc., water will be injected after the drug effect disappears, and a 60-mesh sieve will be set at the water inlet to filter. After 4 days of water injection, 70kg of fermented organic fertilizer will be applied per mu to fertilize and water to cultivate Plankton;

[0028] (2) Floating bed construction:

[0029] The size of the floating bed is 3×2.5m 2 , the mesh size of each floating bed bottom is 4cm 2 Each floating bed is connected with iron wires and placed in the pond i...

Abstract

The invention discloses a hybrid culturing method for bass and crucian by using an ecological-floating-bed-technology-based pond. On the basis of lift habits of various cultured fishes, intercroppingyellow-head catfishes only need to eat residual feeds fully and intercropping crucian plays a role in removing excrements of the bass. When the crucian and yellow-head catfishes, together with the bass, are cultured together in a pond, a phenomenon that the water quality is affected by the residual feed corruption and deterioration is prevented, the ecological balance of the pond is kept, and thecrucian and yellow-head catfish yields are increased additionally. With the biological floating bed technology, water hyacinth is transplanted and the coverage rate of the water hyacinth on the watersurface is controlled, so that nitrogen and phosphorus transformation effect is fully utilized, the dissolved oxygen content in the water is ensured, and biomass of the green alga and blue-green algaeand the like is reduced obviously. Therefore, the purification effect of the culturing pond water is realized; and thus the healthy growth of fishes is promoted effectively and the culturing yield isincreased.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating perch and crucian carp in ponds using ecological floating bed technology. Background technique [0002] In order to pursue economic benefits, traditional aquaculture overuses aquaculture water, which leads to deterioration of water quality and seriously affects the green and healthy development of my country's aquaculture industry. Therefore, related research on improving the aquaculture water environment and constructing an environment-friendly and efficient aquaculture model has become a hot spot in the field of aquaculture research. [0003] Water hyacinth (Eichhornia crassipes) is a monocotyledonous perennial plant belonging to the genus Eichhornia crassipes. It has a fast propagation speed and is a good source of feed and organic fertilizer. Water hyacinth was introduced to my country from South America in the 1930s, and was widely stocked in th...
