CATDOLL : CATDOLL: Do crabs eat moss?

1. Do crabs eat moss?

Crabs are omnivores and eat everything, including moss.

Especially when food is scarce, crabs will eat moss to survive.

Crabs will eat moss when they are hungry.

2. How to clean moss in water

Moss is a general term for many types of algae. Solving the harm of moss on the water surface is a big problem, and there is no very effective way at present. After checking the information, it is recommended to try the following methods. 1. Frequent salvage; 2. Copper sulfate elimination method: Sprinkle 0.7 grams of copper sulfate per cubic meter; 3. Blue alum elimination method: Use 2 to 3 kilograms of blue alum per mu of water surface, add 20 kilograms of water, and spray; 4. Try to use "Moss Sai Ke" produced by Nanjing Furunde Animal Pharmaceutical Co., Ltd., use 200 grams of this product per mu of water surface (1 meter water depth); 5. Raise ducks.

Only by adopting ecological restoration can the problem be completely solved. Ecological restoration is a systematic project. Simply put, it is to restore and improve the river's ecosystem and use a variety of organisms to eliminate the eutrophication problem of the water body. How to implement ecological restoration in the river where you are located requires a detailed plan based on the specific situation.

How to remove moss from water.

No matter what you raise, you can't get rid of the moss in the cement pool. It is recommended that you take out the red carp and sprinkle some lime. After a day, the moss can be removed. Then drain the water in the pool, refill it with water, and put the red carp in.

How to remove moss from fish tank

The main reasons why fish tanks grow moss are as follows:

1. Too many tropical fish; 2. Too many nutrients in the water, especially too many nitrogen compounds; 3. Direct sunlight; 4. Water pollution, excrement is not cleaned up in time; 5. Insufficient dissolved oxygen.

Moss grows very quickly, so it is best to remove it as soon as it appears. The main prevention methods are:

1. Reduce the number of fish;

2. Change the water regularly, such as once a week, changing one-quarter to one-third of the water to reduce excess waste and lower nitrates and phosphates in the water;

3. Control the amount of food you feed, twice a day, 5-10 minutes each time to finish eating, and it is best if there is no residual food left in the tank;

4. Plant honey aquatic plants and fill the bottom bed with them, leaving no empty space;

5. Avoid direct sunlight;

6. Use moss remover (algaecide);

7. Add moss-eating fish and shrimp;

8. Strengthen filtering.

In general, although there are many ways to remove moss, none of them is perfect, and prevention is the best approach. You can prepare a magnetic brush specifically for cleaning moss on the glass wall and clean the moss off the tank wall at any time every week.

There are often some smooth things growing in the fish tank, which are mosses. Mosses can grow on the walls of the fish tank, on water plants, on the artificial bridges and rocks. Mosses will pollute the water quality and destroy the living environment of the fish. Therefore, if you find mosses growing in the fish tank, you must find a way to remove them to ensure the healthy life of the aquarium creatures.

Moss reproduces very quickly and has a very strong reproductive capacity. There are several ways to remove moss. Farmers can choose the most effective and appropriate method to remove moss according to the actual situation.

First of all, the best and quickest way to completely remove moss is to give the fish tank a thorough cleaning. First, transfer the fish to a safe water environment, then start cleaning the fish tank, completely remove the moss, then pour in new water, and after the water is ready, put the fish back in to breed again.

Secondly, if the moss in the fish tank is not very serious, you can choose algaecides, or put in some moss-eating fish and shrimps when cleaning it, and then insist on regular water changes to ensure that the moss does not reproduce excessively, and then remove the moss through long-term treatment.

Finally, in the process of fish farming, measures should be taken to prevent the growth of moss. For example, the fish should be fed an appropriate amount of food, ensuring that they eat for 5-10 minutes every day. There should not be any extra residual fish in the fish tank to prevent water pollution and the growth of moss. At the same time, water filtration and purification should be strengthened. In addition, the lighting time should be reasonable, ensuring that the fish get the light they need every day, and also pay attention to preventing direct sunlight to prevent the rapid reproduction and growth of moss.

Just buy a cleaner fish.

3. Is it good to have moss in the crab pond?

It is not good to have moss in the crab pond. You need to deal with it properly. The steps are as follows

One is that there is water in the crab pond during the winter and it is not drained, cleaned, or disinfected in the spring. The other is that the pond is not fertilized properly before the crab fry are released, resulting in the water being too clear. When moss grows in large numbers in the crab pond, the main remedial measures are as follows: (1) When a large amount of moss appears before the crab fry are released, quicklime can be used to kill it. 2 kg can be sprinkled per mu of water surface.

(2) After stocking, raise the water level in the pond as much as possible to enrich the water, and use appropriate drugs.

1. After catching the winter aquaculture species, drain the pond water, be careful not to accumulate water, expose the pond to the sun and freeze it, and spread quicklime at 10-20kg/mu throughout the pond.

2. Remove impurities and firewood from the bottom of the crab pond to reduce the chance of moss attaching and growing.

3. Before breeding in the crab pond, soak the pond with water half a month in advance and drain it several times, then add enough water, clean the pond with 20ppm tea seed cake, kill harmful fish impurities, and do not discharge. After applying tea seed cake, it can cultivate algae with fertilized water and inhibit the growth and germination of moss. The toxicity of tea seed cake will disappear after a week. After that, the stocking of seedlings can be carried out with water to prevent the loss of fertilized water. In the early stage of breeding, according to the changes in water color, additional fertilizer or water can be added to adjust the pond water so that the reproduction of algae in the pond reaches a certain density. This can not only prevent the occurrence of moss, but also promote the healthy growth of fish, shrimp and crabs, and the effect is very ideal.

4. Planting submerged plants such as golden duckweed, Malayan pondweed, Vallisneria, and Ionella in crab ponds in winter and before Qingming Festival can help crabs ① become good natural and palatable bait; ② become a natural habitat for crabs, which is conducive to their molting and hiding, increasing their survival rate; ③ photosynthesis of water plants can decompose organic matter and improve water quality; ④ crabs walk on water plants without contacting sludge, and their bellies are white, giving them a good appearance. Lush water plants will not produce moss.

5. Use manual removal. Two people use bamboo poles to hold the moss and roll it up, which can make the lush moss relatively smooth. You can also use a special moss rake and net to remove it or drain the water.

6. If it still doesn't work, you can use complex copper products, such as "Green Moss Net" produced by Zhejiang Freshwater Fisheries Research Institute, "High Osmotic Complex Copper" produced by Dingzhou Rongding Water Environment Biochemical Technology Co., Ltd., and "Moss Algae Net" produced by Shanghai Zhongyu Science and Technology Research Institute. The manufacturers generally have instructions on how to use it.

7. The death and rot of moss in large quantities will cause pollution to the bottom soil. You should change the water or use 5 kg/mu of photosynthetic bacteria once every half a month, or use quicklime to disinfect the bottom soil.

After the pond is cleaned, the most effective and economical method is to plant aquatic plants.
