Problems solved by technology
These microorganisms have certain effects in purifying or regulating aquaculture water, but they are affected by the source, purity, and dosage of the strains. They are not very clear about the nutritional and immune functions of aquatic animals, and there is no unified quality and testing standards. Lack of regulation and monitoring in production and application

Embodiment Construction
[0020] The method for utilizing chlorella to purify heterogeneous gibel crucian carp culture water provided by the present embodiment comprises the following steps:
[0021] 1) Expansion and cultivation of Chlorella species:
[0022] Adopt Chlorella vulgaris (Chlorella vulgaris) provided by the laboratory cooperated by Nanjing University of Science and Technology, its number is FACHB-1086, add the culture medium, carry out light cultivation and expansion in the incubator, the light intensity is 3000Lux, cultivate for 10 days, cultivate to a chlorella concentration of 10 10 cell / L.
[0023] 2) Disinfection of the breeding pond and fish body, feeding and domestication of heterogeneous gibel crucian carp fry in the fish pond:
[0024] The size of the breeding pond is 100cm×60cm×80cm, and the pond is cleaned with fresh quicklime.
[0025] Purchase 450 heterogeneous gibel crucian carp fry of 29.0-32.2 grams, generally consistent in shape, strong in physique, complete in scales, ...

The invention discloses a method for purifying carassius auratus gibelio aquatic water by means of chlorella. The method comprises the steps of 1, conducting population expansion culture of chlorella; 2, conducting ingestion domestication on carassius auratus gibelio fry; 3, applying the chlorella subjected to population expansion culture in the step 1 to the aquatic water in a culture pond; 4, placing carassius auratus gibelio subjected to ingestion domestication in the step 2 in the culture pond, wherein the step 1 and the step 2 can be conducted in random order. By the adoption of the method, operation is convenient, implementation cost is low, the content of harmful substances such as ammonia nitrogen and nitrite nitrogen in the carassius auratus gibelio aquatic water can be quickly and effectively restrained, and meanwhile, the concentration of dissolved oxygen can be increased and a pH value suitable for growth of carassius auratus gibelio can be maintained.
Description
technical field [0001] The invention relates to a method for purifying heterogeneous gibel crucian carp culture water by using chlorella, belonging to the technical field of aquaculture. Background technique [0002] Aquaculture is facing many problems, such as the degradation of aquaculture species, high-density cultivation in ponds, the use of untreated industrial and domestic wastewater for cultivation, pond aging, especially the current feeding-based cultivation mode, residual bait, feces, Nitrogen, phosphorus and other eutrophication factors are discharged into the water body, so that the chemical oxygen demand, biological oxygen demand, ammonia nitrogen, nitrite, etc. in the aquaculture water body seriously exceed the standard, resulting in the deterioration of the aquaculture water body and endangering the safety of aquaculture production and product quality . [0003] At home and abroad, it is mainly through certain fungi in microorganisms, such as Bacillus subtilis...
