Problems solved by technology

However, the water body of the existing wild lakes is rich in harmful substances such as toxic substances and toxic blue-green algae, and the temperature is relatively high in summer. The ability to live and survive is obviously reduced, and the decline rate is more obvious with the increase of temperature, and it is difficult to survive for a long time, which greatly limits the application of daphnia in water ecological restoration.

Embodiment 1

[0055] The water flea domestication method of the present embodiment specifically comprises the following steps:

[0056] A: Collect some water fleas (Cladocera) in the wild;

[0057] B: Place daphnia in the first culture pool and the second culture pool (there is culture fluid in the culture pool) for domestication and cultivation, the initial temperature of the culture fluid in the two culture pools is 18°C, the water temperature of the second culture pool constant;

[0058] Specifically:

[0059] B1: First put water fleas into the first culture tank, the stocking density is 200-500 per liter of water, and domesticate and cultivate for 8 hours;

[0060] B2: Take out the daphnia, place it in the second culture tank, and cultivate it for 8 hours;

[0061] B3: Increase the temperature of the culture solution in the first culture tank by 1°C, then take out the daphnia and put it into the first culture tank, and acclimatize and cultivate for 8 hours;

[0062] B4: Take out the...

Embodiment 2

[0087] The water flea domestication method of the present embodiment specifically comprises the following steps:

[0088] A: Collect some water fleas (Cladocera) in the wild;

[0089] B: Place daphnia in the first culture tank and the second culture tank (there is a culture solution in the culture tank) for domestication and cultivation, the culture solution in the first culture tank contains deltamethrin with a concentration value of 0.0000385 mg / L, The initial temperature of the culture medium in the first culture pool is 31°C, the initial temperature of the culture medium in the second culture pool is 18°C, and does not contain deltamethrin;

[0090] Specifically:

[0091] B1: First, put water fleas into the first culture tank at a density of 200-500 per liter of water, and then put microcystin-LR at a concentration of 1-3 mg / L into the first culture tank, and domesticate and cultivate them for 8 Hour;

[0092] B2: Take out the daphnia, place it in the second culture tan...

Embodiment 3

[0100] The water flea domestication method of the present embodiment specifically comprises the following steps:

[0101] A: Collect some water fleas (Cladocera) in the wild;

[0102] B: Place daphnia in the first culture tank and the second culture tank (there is a culture solution in the culture tank) for domestication and cultivation, the culture solution in the first culture tank contains deltamethrin with a concentration value of 0.0000385 mg / L, The initial temperature of the culture medium in the first culture pool is 31°C, the initial temperature of the culture medium in the second culture pool is 18°C, and does not contain deltamethrin;

[0103] Specifically:

[0104] B1: First, put water fleas into the first culture tank at a density of 200-500 per liter of water, and then put microcystin-LR at a concentration of 1-3 mg / L into the first culture tank, and domesticate and cultivate them for 8 Hour;

Abstract

The purpose of the present invention is to propose a method of domestication and use water to repair the ecological repair of the water body.And / or increase the concentration of the toxic substances in the cultivation solution until the temperature of the cultivation liquid reaches the predetermined temperature and / or the concentration of the toxic substances in the culture liquid to the highest concentration of the predetermined.Algae toxin ‑LR, completes the temperature and domestication of water turmoil and the toxic substance tolerance.The water -based water tadpoles that are domesticated in accordance with the current invention of the water crickets are put into the water body that is severely contaminated with toxic substances and algae.

Description

technical field [0001] The invention belongs to the fields of environmental protection and biotechnology, and in particular relates to a method for domesticating water fleas and a method for ecologically restoring nutrient-rich water bodies by using water fleas. Background technique [0002] The reason why the algae in the water broke out is that various human production activities discharge nutrients such as nitrogen and phosphorus into rivers, lakes and other water bodies. When the ecological self-purification ability of lakes is destroyed, nutrients such as nitrogen and phosphorus continue to accumulate in the water body. The accumulation of a large number of single-celled algae, especially cyanobacteria (mainly Microcystis aeruginosa) floods and seriously pollutes the water quality. Most of the cyanobacteria cells have a well-developed alginate layer and are surrounded by a thick layer of polysaccharides. These alginates and polysaccharides can hardly be decomposed by th...
