Culture method with spatial mixing of aquatic gordon euryale and fishes

Abstract

The invention discloses a culture method with spatial mixing of aquatic gordon euryale and fishes. The method includes the steps that a fishpond in an inverted isosceles trapezoid shape is arranged, a double-layer net is arranged around the fishpond, a water heating device and a water temperature control device are arranged, and water injection ports and water drainage ports are formed in the four corners of the fishpond; after the dried fishpond is desilted and exposed to the blazing sun for a long time, gordon euryale seeds are sprouted in air without soil, then sowing is conducted, and then water is injected along with early-stage growth of gordon euryale; after water culture, fry are put in, and the fry are fed with feed; disinfection devices are arranged on the water injection ports, compound bacteria and compound sodium nitrophenolate are splashed, and the fishpond is disinfected after harvesting and catching. Fishes cultured through the method grow fast, and meanwhile the natural flavor is maintained; by utilizing photosynthesis, planted gordon euryale absorbs nutrient substances such as nitrogen and phosphorus in water in the fishpond through the developed roots, and produced stems and fruits can be used and have economic benefits.

Description

technical field [0001] The invention belongs to the technical field of fish breeding, and in particular relates to a breeding method for spatially mixing aquatic Gorgon fruit and fish. Background technique [0002] Since the middle of the 20th century, the development of world aquaculture has made an important contribution to the global food supply. my country is the largest aquaculture country in the world. The aquaculture output has exceeded the capture output for more than 20 years. The aquaculture industry has become an important industry in my country to increase farmers' income, ensure food supply, and promote rural economic development. The so-called freshwater aquaculture mainly uses inland fish ponds, rivers, reservoirs and other areas to breed economical aquatic products. Because freshwater aquaculture has the characteristics of less investment, stable production, and variety of species, it occupies a relatively large proportion in my country's aquatic product aqu...

Problems solved by technology

[0004] When the fish is monocultured, the species is single, the fish pond space and feed are not fully utilized, and the benefit is low. When the aquatic gorgon is mixed with fish, it conforms to the ecological cycle of the fish pond
