Embodiment 1

[0025] The test was carried out in 9 cement pools from August 2, 2016 to September 16, 2016. The size of the cement pool is 2m×1.5m×1.2m, and tap water is injected into the depth of 70cm, and the water injection volume is 2.1m 3 , Oxygenated with air head, no water change during the test. One-fifth of the area is covered with sunshade nets above the cement pool to provide shade for fish to prevent exposure to the scorching sun.

[0026] Trichosanthes for the test was produced in Shanghai. It was brought back to the laboratory in July 2016. It was rejuvenated with Hoagland's nutrient solution prepared by the laboratory. After 3 days, it was transplanted in an ecological floating bed and fixed with foam boards. 5 plants of Trichosanthes were transplanted in each floating bed. Vegetables, the total weight is about 40g. flower He and crucian carp were purchased from the local aquatic product market in July 2016, and domesticated after soaking in salt solution. After 7 days, fi...

Abstract

The invention provides an aquaculture method for achieving water purification and algae control of freshwater aquaculture water. The aquaculture method comprises the step of aquaculturing flower and anodonta woodiana in water in which lythrum salicaria is aquacultured. By the aquaculture method, a significant effect of regulating and controlling the water quality of the freshwater aquaculture water is achieved, effective regulation and control of the total nitrogen, the total phosphorus, the ammonia nitrogen, the nitrite nitrogen, the orthophosphate, the nitrate nitrogen and the phytoplanktoncommunity structure can be achieved, a good water purifying effect is achieved, and the economic benefits of aquaculture are increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture and the technical field of freshwater treatment, in particular to a cultivation method for purifying and controlling algae in freshwater aquaculture water. Background technique [0002] Numerous studies have shown that aquaculture water is a complex environment, and it is difficult to effectively purify water by relying solely on a single organism or a single method. Cleaning organisms are the core of the aquaculture environment cleaning projects that have been vigorously carried out in recent years, that is, the organic combination of aquatic plants, filter-feeding animals and slough-feeding animals. Omnivorous fish such as barracudas and barracudas living in seawater play the role of carrion-eating animals in the combination. Compared with silver carp and bighead carp, these omnivorous fish can eat organic debris in addition to smaller algae, making up for the shortcomings of filter feeders...
