How to breed lobsters and what problems to pay attention to

The lobster feeding method is as follows:1. Breeding facilities. Breeding lobsters should build ponds with flat bottoms, good water storage and sufficient water sources, with an area of 4-10 acres, and the water depth should be kept in the range of 1 meter to meters, and during the breeding period, plastic film should be used to build protective nets along the edge of the pond to avoid lobsters escaping.

2. Preparation for stocking. One month before stocking lobsters, the water in the pond should be drained, the excess silt should be removed, and then the pond should be disinfected with bleaching powder, and then the rotten farmhouse fertilizer should be applied to it to cultivate plankton, and algae and aquatic plants should be planted at the bottom of the pond to provide a place for the lobsters to hide, rest and molt.

3. Feeding management. Lobster eating is more miscellaneous, in the process of breeding, you can be fed twice a day between July and October every year, mainly fish, snail meat, shrimp meat, watermelon, so that it can consume enough nutrients, and the rest of the season should be fed once a day, and it is best to feed at night, so that the amount of lobster food increases.

1. Management of water level and water quality.

Generally, the water level of pond breeding crayfish is kept at about 1 meter, because crayfish have the habit of burrowing above the water level, and the water level can not be high or low, otherwise the crayfish repeated burrowing is easy to consume the energy of crayfish, resulting in reduced production.

2. Plant grass and throw snails.

Appropriate density of aquatic plants can provide plant bait and animal bait for crayfish, increase the amount of dissolved oxygen in the pond through the photosynthesis of aquatic plants, and provide a place for crayfish to escape the heat and cool down in the summer high temperature season. It can also provide a safe place for crayfish to molt and avoid predators, and aquatic weeds are particularly important.

3. Bait feeding technology.

The principle of bait feeding ensures that the crayfish are full, well-eaten, evenly eaten, and finished, leaving no residual bait. The daily feeding amount should be arranged according to 2%-5% of the total weight of crayfish in the storage pond. 2 times a day, 1 time in the morning and 1 time in the evening, and the amount of feeding in the evening accounts for 60%-70% of the whole day.

4. Prevention and control of pests and diseases.

Adhere to the principle of giving priority to prevention, combining prevention and treatment, preventing diseases first, and treating diseases early, and do a good job of disease prevention on a regular and targeted basis.

5. Daily management.

Insist on patrolling the pond once a day in the morning and evening, carefully observe the activities, growth and feeding of crayfish, pay attention to changes in water quality, and deal with abnormal situations in time.

6. Catch the big and keep the small, and go public in a timely manner.

After about four months of careful breeding, the crayfish that have reached the commercial specifications can be caught and marketed in a timely manner, and the large and small fish can be caught and marketed in a balanced manner, so as to reduce the density of the pond shrimp and promote the rapid growth of crayfish.

I can raise it. Choose the pond: the water source of crayfish breeding requires fresh water quality, sufficient dissolved oxygen, no pollution, the width of the pond is more than 3 meters, and the pond area should not be too large, generally 3-8 acres is appropriate. It is worth noting that crayfish have a strong ability to escape, and it is necessary to do a good job in the construction of anti-escape facilities.

Pond disinfection: Pond disinfection can effectively kill predators (catfish, loach, snakehead, rats, etc.) and wild miscellaneous fish (carp,) competing for food in the pond. crucian carp, etc.) as well as pathogens, quicklime and bleaching powder can be used.

Planting aquatic weeds: aquatic weeds occupy a pivotal position in lobster farming, the general area accounts for half of the pond is appropriate, you can choose low-pole reeds, callus white, etc., and you can also put some empty cans at the bottom, bamboo tubes, tree roots, etc.

Now there are too many people who breed lobsters, and the total sales expenses of the public have been declining in the past two years because of the problem of epidemic prevention and control.

Crayfish farming is a systematic project course, it can be said that crayfish farming can make money, whether there are many factors of success and failure, such as environmental damage in the field, water quality control, concentrate feed management methods, etc.

All of the above are the problems that must be paid special attention to in the whole process of crayfish farming, and there are other situations that must be paid special attention to in clear water pond farming.

Basically, it is an extensive operation to carry out breeding, and there is no technical aspect to talk about at the breeding level, and even others need to be simple and direct in raising the sky, so it ends up losing money. The key point here is that he ignores the standards that must be given for the growth and development of crayfish when crayfish are farmed, such as grooves, aquatic plants, etc. Therefore, the first thing that must be paid special attention to crayfish farming is that everyone should prepare a suitable site or natural environment for crayfish farming.

The second thing to keep an eye on is the weather. Aquatic product breeding must be concerned about weather changes, due to genetic mutations of weather conditions are likely to cause ponds. Therefore, it is important to pay attention to the weather forecast every day and check the weather forecast with your mobile phone, and pay attention to the weather changes in the next few days.

The third hurdle that must be paid special attention to is the "May Prophecy." May is the peak time for crayfish pest and disease outbreaks, and it is also at this time that the highest number of deaths occurs. Therefore, it is necessary to be vigilant at all times after entering April, and it is a wise choice to catch and sell the shrimp early, reduce the relative density of farming, and let some of the crayfish in the early breeding be cashed.

The fourth thing to watch out for is predator damage. After the natural enemies enter the shrimp pond, the crayfish are very prone to injury or being eaten, which also seriously affects the production. Therefore.

Be sure to take care to eliminate natural predators of crayfish, such as rats, snakes, crucian carp, silver carp, birds, etc.

The fifth is to effectively use the shrimp seedlings in the pond, which can reduce the purchase cost of shrimp seedlings, that is, reduce the expenditure of their own breeding.

The upper level is all about the most important issues that must be paid special attention to throughout the whole process of crayfish farming, not only in terms of cost management, but also in terms of success and failure. Therefore, it should be taken seriously.

Now it is autumn, which is the season of rapid growth of crayfish, what are the key points to pay attention to in the breeding process?

Crayfish cannot adapt to grow in a high or low temperature environment, so the growth temperature should be controlled in the range of 15-35 degrees, and the most suitable temperature is about 20-25 degrees. If it exceeds 15-35 degrees, then the growth of crayfish will be affected, appetite will be reduced, the growth rate will slow down, and even stop growing.

Breeding density is very important, once the number of breeding is too much, it will affect the growth of crayfish, and also increase the incidence of crayfish. In addition, it is difficult to manage if the culture is too dense, and it is very easy to suffer from hypoxia, which increases the mortality rate of crayfish. It is necessary to ensure that the breeding density is reasonable in order to ensure the healthy growth of crayfish.

Nutrition is a common problem for many farmers, and there is no correct feeding and selection of crayfish feed. Crayfish not only eat meat, but also with a little grass feed. You can plant some vegetables or aquatic plants around the pond appropriately, and then mix them with various carnivorous feeds and feed them reasonably.

At present, many farmers will mix Staling into the feed, which can not only effectively improve intestinal health and enhance intestinal immunity; It can also protect the liver and gallbladder and promote digestion and absorption. In addition, Staling also played an active role in inducing food and promoting growth

Water quality is an aspect that everyone is relatively easy to ignore, although crayfish can live in an environment with poor water quality, but it is also prone to produce many parasites, which will cause harm to the body after people eat it. Therefore, the water quality of crayfish must be controlled at a clean and fresh level, and clean water quality can promote the growth of crayfish and improve the meat quality. Farmers in the main coastal producing areas such as Jiangsu and Zhejiang are generally using Youjiling, which can inhibit the generation of toxic substances such as ammonia nitrogen and nitrite, increase the amount of dissolved oxygen in the water body, and repair the bad water body; It is rich in nutrients such as small peptides, which can also promote the growth of beneficial algae in the water body and cultivate natural bait; In addition, UCL can also reduce the stress response caused by changes in the external environment and protect aquatic animals

Although crayfish are relatively adaptable, there are still many diseases if they are not managed well, such as rotten shell disease, soft shell disease, etc. Disease is very unfavorable to the growth of crayfish, and we must pay attention to disease prevention in the process of breeding crayfish. Strengthen the management of ponds, do a good job in water quality treatment, and enhance their own breeding technology, so that they can respond to various situations in a timely manner.

As the weather turns colder, crayfish farming enters the late growth stage, during this time should be fed more feed and with the use of Youjiu aquatic animal protection products to enhance physical fitness, for the coming winter. Improving the survival rate in winter is the key to a bumper harvest in the coming year.

Crayfish must pay attention to anti-theft in the breeding process, because crayfish ** is not cheap, you must be careful, others come to steal crayfish at night.

First of all, it is necessary to choose a suitable area, and at the same time, when breeding, we must pay attention to the temperature of the water, we must pay attention to the amount of water, and we must do a good job of disinfection and sterilization, we must replace the water quality in time, and we must also choose some varieties with a relatively high survival rate.

It is necessary to pay attention to the temperature of the farmed crayfish, the state of the soil, the state of water sugar, the presence of some plankton, and the emergence of some infectious diseases.

Crayfish farming is a systematic engineering or discipline, it can be said that there are many factors affecting whether crayfish farming can make money, success or failure, such as changes in the external environment, water quality management, feed management, etc. The above are all problems that need to be paid attention to in the process of crayfish farming, and there are other problems that need to be paid attention to in clear water pond aquaculture.

On the Huinong network, some users have shared the case of crayfish farming in Qingshui Pond, which is basically based on the sky to eat, and there is no technology at all in the aquaculture, and it is even more simple and rude than people releasing the sky, so in the end it ended up at a loss. He mainly ignored the need to provide conditions suitable for the growth of crayfish when cultivating crayfish, such as deep ditches and aquatic plants. Therefore, the first thing to pay attention to in crayfish farming is that we should prepare a suitable place or environment for crayfish farming.

The second thing to watch out for is the weather changes. To engage in aquaculture, we must pay attention to weather changes, because sudden weather changes may cause pond turning. So, pay attention to listening or checking the weather forecast with your mobile phone every day, and pay attention to the weather changes in recent days.

The third thing to pay attention to is the "May Curse". May is the peak season for crayfish disease outbreaks, and it is also at this time that the most deaths occur. Therefore, after entering April, we should always be vigilant, and catch shrimp in advance**, reduce the breeding density, and let some of the crayfish in the early stage be realized.

The fourth thing to pay attention to is the hazard of natural enemies. After the natural enemies enter the shrimp pond, the crayfish are prone to injury or being eaten, which seriously affects the yield. So. Be sure to take care to remove crayfish predators, such as rats, snakes, blackfish, catfish, water birds, etc.

The fifth rational use of shrimp seedlings in the pond can reduce the purchase cost of shrimp seedlings, that is, reduce the cost of their own breeding.

The above aspects are the key issues that need to be paid attention to in the process of crayfish farming, which is not only related to cost control, but also related to the trend of success or failure. Therefore, attention should be paid to it.
