CATDOLL : CATDOLL: Is it easy to raise shrimp? What should we pay attention to when raising them?

If you want to raise shrimp well, you must give it a particularly good environment. I must find a relatively healthy rice field, because the rice in the rice field itself will have some minor diseases, which may affect the health of the shrimp. In addition, the amount of exercise of shrimp is particularly large. If one shrimp is sick, it is very likely that all the shrimp in the rice field will be infected.

Because the quality of water resources is also very important for shrimp, it is recommended that you raise them near water resources, because it will be more convenient to change the water in the fish tank. The seedlings of shrimp are particularly small, so in order to prevent the small shrimp from escaping, you must dig some circular ditches around the rice fields, preferably a little deeper.

We can actually put a small wooden board or a small-hole fishing net on the small hook about ten centimeters above the river surface, so that the small shrimp will not escape. And because the shrimp fry are particularly active, we try to find a larger rice field, and it is best to have water and electricity projects connected in the early stage, because we need to add a certain amount of oxygen to the water in the pond in the later stage.

When we buy shrimp fry, we must go to a slightly larger farm to buy them, because the shrimp fry there will be healthier. When we choose the shrimp fry, we try to choose the more active ones. Some shrimp fry have poor gastrointestinal function, so they don't like to move and will stay underwater all the time. We can't buy such shrimp fry. Especially healthy shrimp fry often emerge from the water. We can buy more of such shrimp fry, so that they are easier to survive after we buy them.

After I buy the shrimp fry, I prepare a large basin with relatively clean water, put some special disinfectant for breeding in the water, and then put all the shrimp fry in the basin. We can buy some concentrated feed for breeding mud shrimp, divide the concentrated feed into small pieces and put them in small basins, because in this way the mud shrimp will not be particularly nervous when it arrives in an unfamiliar environment. The mud shrimp cannot stay in this kind of water for too long, at most two hours a day. After three days of continuous disinfection of the small mud shrimp, it can be put into the rice field.

Site selection

The breeding site is similar to that of other fish and shrimps. You can build your own pond or use a rural pond. The size should be 2-5 mu. The water level should be between 1-2 meters. The pond should have some slope and be slightly tilted, which is conducive to drainage. The water quality of the fish pond must be high. Compared with other fish and shrimps, the requirements of the water quality of the mud shrimp are higher and it is more sensitive to water pollution. Clear water quality is the key to ensure its molting and growth.

Cleaning and fertilizing bait

After preparing the breeding site, it must be fully cleaned and disinfected. After the pond water is drained, it must be exposed to the sun for 2-3 days before it can seep water. Ponds with more sludge need to be exposed to the sun for about a month. After the water seeps in, it must be strictly disinfected. Ordinary quicklime powder or bleaching powder can be used for disinfection.

The shrimp feed on zooplankton. Therefore, about a week before stocking, fertilizer and bait should be added. The basic microbial bait in the shrimp pond should be added, and organic and inorganic fertilizers should be the main fertilizers.

Planting

The shrimp is suitable for growing in a temperature of 18-30 degrees. Therefore, the seedlings are generally released in mid-to-late May, when the temperature is relatively stable and suitable for release. In order to ensure the survival rate of the shrimp seedlings, they need to be cleaned up one week before release and placed in water with a salinity of 1.003 for a week before they can be put into the fish pond. Cleaning must be done from shallow to deep, and never on a whim. It can be done at the same time as fertilizing and raising bait.

Feeding and management methods

When the shrimp fry enters the septic tank, it is the daily management method, which mainly includes water quality, feeding, pest prevention and management, etc. Water quality management is extremely important. After the shrimp fry are raised for about 10 days, the water should be gradually released, and lime powder or bleaching powder should be sprinkled to improve the water quality and disinfect.

When the temperature reaches 24-30 degrees, the food intake of the shrimp will increase. This is also the stage of its rapid growth. Therefore, it is necessary to increase feeding to ensure food supply; pest control is the main method, and lime mold is sprayed regularly at each time period, and calcium can also be supplemented to promote shelling growth.

Note:

1. Add 10-20cm of fresh water into the pond regularly. The fresh water added must be strictly filtered and contain a large amount of river, lake water with rich dissolved oxygen content. Install an aerator to oxygenate; prepare oxygenators for emergency use.

2. Apply "Bailede" + "Duohesu" once every half a month. In the morning, when the dissolved oxygen content in the shrimp pond is rich, add water to fully dissolve and spray the whole pond to prevent the water from being too concentrated and the algae from dying when the wind frequency changes, improve the water quality and improve the clarity of the water surface.

3. To improve the physical fitness of grass shrimp, take "Astragalus" + "Savi" (one set of 300 kilograms of feed) orally on a regular basis to enhance the resistance of grass shrimp, increase the muscle density of grass shrimp, and reduce the phenomenon of long-term white body of grass shrimp.

4. For algae death and harmful substances, sprinkle "Bailede" + "fruit root element" every 10 days to detoxify water and human body.

5. Use bottom cleaning every week to improve the bottom dissolved oxygen environment.

6. Flexible feeding: Insist on frequent feeding and feed less. Do not feed when the dissolved oxygen is less than 4 mg/L, feed more when the water quality is good, feed less when the water quality is poor, feed less or do not feed when the northwest wind blows or the temperature drops, and feed less on the day when a large number of shellfish are molting.

Of course, the shrimps are very easy to raise. The issues that must be paid attention to when raising shrimps are that first, you must build a usable, pollution-free pond, then clean the fertilizer and bait, and disinfect the farm thoroughly. The water in the pond must be drained and exposed to the sun for three days before stocking. Generally, the stocking is in late May, and the survival rate will be particularly high. In addition, the water quality must be kept clean, and the shrimps must be fed on time every day, and pests and diseases must be prevented and controlled in a timely manner.

It is very easy to raise. During the breeding process, you must choose a relatively suitable area, and you must ensure the water quality, and you must replace the water in time. You must also ensure the nutrients in the water, and you must choose high-quality feed.

It is relatively easy to raise shrimp. When raising them, you should be careful not to have natural enemies of shrimp in the breeding pond.
