Problems solved by technology

However, the water body of existing wild lakes is rich in toxic substances and harmful substances such as toxic blue-green algae, and the temperature is high in summer. Unaccustomed water fleas ingest algae and algae and The ability to survive is obviously reduced, and it is difficult to survive stably for a long time, which greatly limits the application of daphnia in water ecological restoration.

Embodiment 1

[0029] The temperature tolerance and domestication method of water flea in this embodiment specifically includes the following steps:

[0030] A: Collect several water flea (Cladocera) in the wild;

[0031] B: Place the water flea in the first culture pool and the second culture pool (there is culture fluid in the culture pool) for cross domestication and culture. The initial temperature of the culture fluid in the two culture pools is both 18°C. The temperature of the culture solution remains unchanged;

[0032] Specifically:

[0033] B1: Put the water flea into the first culture tank at a density of 200-500 per liter of water, and domesticate for 8 hours;

[0034] B2: Take out the water flea, place it in the second culture tank, and domesticate for 8 hours;

[0035] B3: Increase the temperature of the culture solution in the first culture pool by 1°C, then take out the water flea and put it into the first culture pool, and acclimate for 8 hours;

[0036] B4: Take out the water flea, pl...

Abstract

The invention aims at providing a temperature resistance domestication method for daphnia and a method for conducting ecological repair on a water body through daphnia. The method includes the steps that A, daphnia is placed in a breeding solution to be bred for a set period of time, and the temperature of the breeding solution is changed into the preset temperature according to the same tendency; B, the step A is repeatedly executed till the temperature of the breeding solution reaches the preset limiting temperature, beneficial microorganisms are put in, and domestication of daphnia is completed. By putting daphnia domesticated according to the method in the water body rich in toxic substances and algae, the water body can be purified, the underwater ecological balance can be repaired, and the ecological self-purification of the water body can be achieved.

Description

Technical field [0001] The invention belongs to the field of environmental protection and biotechnology, and particularly relates to a temperature-resistant domestication method of water flea and a method for ecological restoration of nutrient-rich water bodies by using water flea. Background technique [0002] The algae in the water erupted because of various human production activities, which discharged nutrients such as nitrogen and phosphorus into rivers, lakes and other water bodies. When the lake’s ecological self-purification ability was destroyed, nutrients such as nitrogen and phosphorus continued to be in the water body. It accumulates in large quantities, which results in the flooding of single-celled algae, especially cyanobacteria (mainly Microcystis aeruginosa), and serious water pollution. Most cyanobacteria cells have a well-developed layer of algin, and the outside is surrounded by a thick layer of polysaccharides. These algins and polysaccharides can hardly be d...
