What fish eat green algae in the pond What fish eat green algae

Grass carp, Thai dace, scavengers and anti-swimmer cats all eat green algae, which can pollute the pond water, so be careful to clean up the green algae. Chlorella have photosynthetic pigments, and typical green algae cells may or may not be motile. Cells** have vacuoles, pigments are distributed in plastids, and the shape of plastids varies with species.

The cell wall is made up of two layers of cellulose and pectin. Common green algae in activated sludge are chlorella and sponges.

The following types of fish will eat green algae:

1.Haddock Flying Fox: This is a recognized algae-eating fish with a body color between green and black that feeds on algae. When it eats algae, its mouth acts like a vacuum cleaner, absorbing the algae attached to the stone.

2.Pixies: This fish is only 2-3 cm long and feeds on algae, making it suitable as an ornament in a fish tank.

3.Beard: This fish can be up to 10 centimeters long and feeds on algae and cleans the algae inside the tank.

4.Monkey Flying Fox: This fish loves to eat algae and microorganisms, and can reach a body length of up to 15 cm, making it suitable as an pelagic fish in a fish tank.

5.Black Mary: This fish can reach up to 10 centimeters in length and feeds on algae, which cleans the algae inside the tank.

In addition to the fish mentioned above, there are many other fish that eat green algae, such as grass carp, Thai dace, scavengers, and anti-swimming cats.

There are many fish that <> eat green algae, such as black line flying fox, elf fish, **beard, little monkey flying fox, black Mary and so on. It should be noted that as tool fish, it is easy not to let them into the tank, which will cause disturbances among other fish, and there is a certain risk of polyculture. If you want to remove algae, you can take out the fish and clean it manually, or you can choose an algaecide and pour an appropriate amount into the water.

The black flying fox, the black flying fox can remove the green algae in the tank, but it needs to be kept in a hungry state; Scavengers, scavengers can also clean the green algae at the bottom of the tank, but the water needs to be changed regularly; Pixies, elves can eat green algae at the bottom of the tank, pay attention to the algae food after the green algae is eaten up; Golden moss rats, golden moss rats can eat green algae when they are young; Black Mary and Black Mary can also feed on the green algae at the bottom of the tank, but they need to choose fish polyculture with similar growth habits.

If you want to remove algae from the fish tank, it is recommended not to feed them, because only in a hungry state, the black fox can better clean up the algae produced in the tank. And during the feeding period, it is necessary to cover the top of the fish tank to avoid the situation of jumping the tank after the black line flying fox is frightened.

The scavenger is also the most common cleaning fish, and the scavenger itself is a benthic fish that feeds on the green algae and food debris at the bottom of the tank. However, scavengers will also excrete a large amount of feces after eating, so during the feeding period, it is necessary to regularly observe the changes in water quality, and after finding that the water quality has deteriorated, the water needs to be changed in time.

The small size of the pixie allows them to remove green algae from small tanks and feed on snail eggs. However, it should be noted that the pixies can only eat the algae plants at the bottom of the tank, so after the algae shells in the tank are eaten, the pixies will gradually starve to death. Therefore, in the later stage, it is necessary to feed a small amount of algae-containing feed.

The golden moss ratfish is a yellowing species of moss rats, which can play a role in cleaning the fish tank, can eat the moss produced on the tank wall, and has a relatively mild temperament, and can be mixed with other fish. Note that the golden moss rat can only clean the tank when it is a juvenile, and it is easy to harm other fish when it reaches adulthood.

Black Mary fish is also a good clean fish, can eat algae good aquatic plants, and the requirements for water quality are not high, it is easier to raise, you can choose weak alkaline soft water feeding, you need to choose the same growth habit of fish polyculture, so as to avoid poor growth.

<> Filling up new water: Filling the pond with new water, or replacing the pond water, or using micro-flowing water to breed aquatic animals.

Disinfection treatment: 10 kg of quicklime per mu is sprinkled in the whole pool, or bleaching powder with a concentration of 1ppm.

Manual removal: use nylon nets to catch green algae, and the green algae can be used as feed for livestock.

Biological control: Stock some black-shell shrimp, which will use green algae as food.

Deepening the water level: Deepening the pond water level will reduce the area where green algae can attach, speed up the sedimentation rate, and gradually die.

1. Fill with fresh water

1. When there is a lot of green algae, new water should be added, or the pool water should be replaced to improve the cleanliness of the water quality.

2. Usually add water regularly, or use micro-flowing water to breed aquatic animals, and the bad pond water can destroy the growth environment of green algae.

2. Disinfection treatment

1. Use 10 kg of quicklime per mu of pond to sprinkle the whole pond, or splash bleaching powder with a concentration of 1ppm.

2. Use organic fertilizer to avoid the aging of water quality and control the reproduction of filamentous green algae.

3. Splashing copper sulfate solution with a concentration can kill green algae.

3. Manual removal

Nylon nets are used to catch green algae from ponds, and the green algae can be used as feed for chickens, ducks, pigs and other livestock.

Fourth, biological control

1. Put an appropriate amount of black-shell shrimp, which will use green algae as food.

2. Put some fish with licking and scraping epiphytic eating habits.

Fifth, deepen the water level

1. Green algae are attached algae, and deepening the water level can reduce their attachment area and accelerate the sedimentation rate, so that they gradually die.

2. Set up aerators and wave machines in the pond to destroy the stability of the water body, which can also inhibit the reproduction of green algae.

Sixth, muddy mud water prevention

Add pig manure to the yellow clay (the amount of pig manure is about 30% of the yellow clay), mix it into a thin mud, and then splash it on the water surface, 1 time a day, 3-4 times in a row.

7. Combination of scrubbing and medicated bath

1. Scrub the green algae with waste polyethylene mesh, once every 2 months in spring and autumn, and only need to wash once in winter.

September is the peak season for the bloom of green algae, during which time it is washed once a month.

3. After scrubbing, soak it in copper sulfate solution with a concentration of 8ppm for 15-20 minutes, which can kill the residual algae species.

(1) Planktonic algae are producers who can produce organic matter through photosynthesis and provide food for other organisms**; Algae plants carry out photosynthesis and release oxygen at the same time to meet the needs of aquatic life activities (2) Algae plants at night can only respire, not photosynthesis, coupled with the respiration of fish, resulting in a decrease in oxygen in the water, forcing fish to breathe oxygen from the surface air (3) (4) Fish live in water, respire by gills, and water dissolved in oxygen enters from the mouth of the fish and flows out from the posterior edge of the gill cover, and the oxygen in the water is exchanged into the body of the fish through the gills. It can be seen that fish obtain oxygen in the water through their gills If there is a phenomenon of fish "floating head" at dawn in a fish pond, it means that fish need sufficient oxygen for respiration Therefore, in order to prevent the phenomenon of fish floating before dawn, the measures that should be taken are: oxygen is introduced into the water at night, so the answer is: (1) planktonic algae plants; Zooplankton; Food**; Photosynthesis; oxygen (2) respiration; Photosynthesis; Respiration; Oxygen decreases: (3) photosynthesis; Oxygen; Oxygen (4) Oxygen is introduced into the water at night.

Snail farming is the best. If you have to use fish. There is a fish called "scavenger" that is good.

Among the tropical fish, both "black marry" and "kissing" fish can eat green moss.

Yes, but. Are you a fish pond?

Then there is no heating equipment. Fish can't stand it.

It's better to raise snails.

Apple snails are very good at removing algae. It is also easy to reproduce.

It is also relatively resistant to low temperatures.

The water temperature above 14 degrees Celsius is sure to withstand it.

Fish ponds will have green algae because of light, and the microorganisms in the water photosynthesize with sunlight, so try to avoid sunlight, and the ecosystem will be built slowly.

The prevention and control methods are as follows:

1. Pay attention to changes in water quality. If the pool water is too fertilized, it should be filled with new water in time, or the pool water should be replaced to improve the water quality. Usually add water regularly or use micro-flowing water for aquaculture.

2. Regularly disinfect the pool water. 10 kg of quicklime per mu of water surface is sprinkled throughout the pool, or 1ppm of bleaching powder is sprinkled. Decomposed organic fertilizer should be applied to prevent the aging of water quality and control the growth of filamentous green algae.

3. Combination of scrubbing and medicated bath. The scrubbing effect is better with waste polyethylene mesh, which is washed every two months in spring and autumn and once in winter. During the peak bloom season of green algae blooms in May and September, wash once a month to keep it clean.

After brushing, soak with 8 ppm copper sulfate solution for 15 minutes and 20 minutes to kill residual algae species.

4. Kill with copper sulfate solution.

5. Muddy mud water prevention. Add an appropriate amount of pig manure with yellow clay (pig manure is about 30% of yellow clay), mix it into a dilute mud and splash it on the water surface, once a day, splash 3 times and 4 times, save labor and time, and the effect is good.

6. Stocking fish with licking and scraping epiphytic biophagogenesis.

The pond is planted with water banyan or iron crown algae fish, and the fish cannot be eaten. The aquatic plants that fish don't eat are generally sclerophyllous, such as water banyan or iron crown, and these aquatic plants are not eaten by fish.

Eating grass is like eating vegetables, which can supplement vitamins and dietary fiber, so that fish can better digest food, make their bodies healthier and fatter, and you can also raise some small fish that eat algae, which will not only not harm aquatic plants, but also clean the algae in the fish tank and provide some help for the growth of aquatic plants.

Aquatic plants are recommended.

Moss is the most common aquatic plant, as a bryophyte has no roots, it needs to be attached by sinking wood or stones, it is very good to put it in a fish tank to beautify, this aquatic plant can absorb the waste produced by fish fry, has low requirements for light and carbon dioxide, and is easy to raise.

Cow felt is a type of aquatic weed. It does not have strict requirements for temperature, it is widely distributed in our country, it usually grows in rice fields or ponds, this aquatic plant is very dense, like cow hair, with a height of about 2 to 12 cm, it is beautiful and easy to raise in a fish tank.

Staghorn moss is a floating aquatic plant, with a height of 1 to 6 cm, it prefers a warm environment, is afraid of cold, and the temperature should be kept between 15 and 30, and should not be lower than 10 in winter, to ensure healthy growth.
