How can ice beaten crayfish be raised for a long time?

It's not very clear, but the glass slipper is available on the Internet to find relevant information.

1-Environment: Say not much, just go over the back, if the water depth can be placed stones for it to climb, in the water dissolved oxygen is insufficient and when sleeping at night, it can put half of the gills out of the water to breathe, while paying attention to escape, this guy can use pliers to open the way to clip small objects such as wires to escape 2-Food: Kline's is a wide range of food, plant protein and animal protein will be ingested in the wild, and it is the same if you want to raise it for a long time under artificial conditions, you can't just feed the same food, it is recommended to feed small shrimp and small fish, The calcium in it can help the formation of new shells inside the shrimp and improve the survival rate of molting, and try to feed clean vegetables if the plant protein is used, so as not to cause devastating damage to the nerve center of the crayfish with pesticides 3-molt:

If you don't eat for a few days before molting, don't touch it at that time, and rest and recuperate; A few days after molting is also not moving, at that time it is the most fragile, in addition to the teeth are soft, the higher the temperature the faster the hardening, at that time it is best not to scratch it, it is easy to cause the shell to deform, after the shell hardens, to increase the amount of feeding, molting is equal to Nirvana, consuming a lot of its energy, maybe you don't know, every time the molt is a threshold of life and death for the lobster, there are many who die in the shell.

First of all, you need to increase the aquatic weed content in it, in fact, it is to add some food, so that the crayfish can grow faster and grow bigger.

The time that crayfish in the desert ice can only be stored in the refrigerator.

Crayfish has a strong vitality, as long as it is fed and the water is changed every day, it can be fed.

If you want to keep the crayfish for a long time, you can put it in water full of oxygen and change the water appropriately, which can increase its lifespan.

Crayfish can be left frozen for about 20 days.

Crayfish is rich in protein, easy to be decomposed by bacteria to produce cadaver and histamine, although the freezer can inhibit the growth and reproduction of bacteria, but bacteria will still exist, generally crayfish can be stored in the freezer for about 20 days.

Nutritional content of crayfish:

1. From the perspective of protein composition, the protein content of lobster is 18.9%, which is higher than most freshwater and seawater fish and shrimp, and its amino acid composition is better than that of meat, containing 8 essential amino acids that are necessary for the human body and cannot be synthesized or synthesized in insufficient amount;

2. The fat content of lobster is only 0.2 percent, which is not only much lower than that of livestock and poultry meat, and much lower than that of green shrimp and prawns, and most of its fat is composed of unsaturated fatty acids necessary for the human body, which is easy to be digested and absorbed by the human body, and has the effect of preventing cholesterol accumulation in the body;

3. Lobster, like other aquatic products, contains essential mineral components for the human body, including calcium, sodium, potassium, magnesium, phosphorus, and iron, sulfur, copper, etc.

The methods that can make crayfish live longer include large pot feeding methods, glass tank feeding methods, and so on.

1. Large pot feeding method.

Because crayfish are more aggressive, try to spread out the crayfish in a large basin, put an appropriate amount of water in the large basin (the water surface should not be over the top of the crayfish's head, it can be about 2-4 cm), put in the right amount of water so that it can reduce the number of deaths, and can let the crayfish discharge the garbage in the body, the crayfish prefer a dark and damp place, you can cover the basin with a black plastic bag or other things, and you can feed the crayfish some green cabbage leaves, steamed buns, and diced meat during the crayfish.

2. Glass tank feeding method.

After rinsing the lobster, pour it directly into the pool with an air pump or the glass tank to inject oxygen, do not put too much lobster, change the water in the morning and evening, this storage method can store lobster for 5-10 days.

Farmed crayfish management process:

1. Ponds. The water depth of the pond is controlled between 1-, the bottom of the pond is flat, and the pond is compacted around the pond to prevent the lobster from escaping, and the slope ratio of the pond is. Before stocking, 100-150kg of quicklime per mu of pond is used for pond cleaning and disinfection.

After 3 days, the pond was flooded. After 10 days, 300-500kg of decomposed organic fertilizer was applied to each mu of pond to cultivate plankton and provide bait for shrimp seedlings.

2. Stocking. If it is stocking in the dreary summer, 340,000 juvenile shrimp are stocked in each mu of pond, and the specifications are above; If it is stocked in autumn, 10,000 shrimp seedlings are stocked in each mu of pond, and the specifications are above; If it is stocking in winter and spring, 10,000 shrimp seedlings are stocked in each mu of pond, and the size is 100-200 kg.

If it is summer stocking, it is generally carried out in mid to late July every year; If it is autumn stocking, it is generally carried out from mid-August to September every year; If it is winter and spring stocking, it is generally carried out in December of each year or in March and April of the following year. Before stocking, use 4 salt water to soak for about 10 minutes.

3. Feeding. If it is 7 October, the amount of bait is about 8 12 of the weight of the shrimp, and the dry feed or compound feed is planned according to 2 4. In other seasons, the daily feed is about 2-5 of the shrimp's body weight.

If it is 7 October, feed 2 times a day, of which the amount of bait at night is about 60 70, if it is other seasons, feed 1 time a day, the specific feeding time is around sunset every day.

4. Management. The dissolved amount of oxygen is kept above 5mg L, the pH of the water body is controlled between 7, and the transparency of the water body is about 40cm. Every 15-20 days or so, change the water, if it is a high temperature season, every 5-7 days to change the water, each time the amount of water is about 20 30, and every 15 days or so, each mu of pond uses 10-15kg of quicklime water, the whole pond is splashed.

OK. Lobsters are kept in the refrigerator under the freezer strip of the starvation hail, which can extend its shelf life.

The temperature of the refrigerator refrigerator is generally maintained between 3-8 °, at this temperature it is impossible to completely inhibit the breeding of bacteria and microorganisms, put the lobster in for a long time, resulting in the lobster and other foods in the refrigerator to have a cross-smell, it is recommended to keep it for about 2-3 days; If it is placed in the freezer, it can be stored for a long time, and the rotten and withered sails are generally about half a month, and the time should not be too long.

The taste of frozen meat will be more chai, because the moisture is less, which is due to the fact that the temperature of our ordinary household refrigerator cannot reach minus 25 degrees and below, so during the freezing process, the water loss is great. Crayfish can also be put in the refrigerator to freeze, but our ordinary household refrigerator will also encounter the embarrassment of turning shrimp meat into firewood.

Lobster freezer method

Live lobsters are generally recommended to be stored in the cold and freezer room, first clean the lobster, and then put it in a metal basin filled with clean water, as long as the water in the metal basin can cover the lobster, and then put it into the freezer together, when the water and the lobster and shrimp are frozen together, take out the basin, put it at room temperature for a while, pour out the frozen lobster shrimp, pack it in a fresh-keeping bag, seal it, and put it in the refrigerator for freezing.

To keep lobsters fresh and stored, the following steps can be taken:1Fresh Buy:

Try to choose fresh, vibrant lobsters. Pay attention to their mobility and appearance, and choose lobsters with no obvious damage or lesions. 2.

Storage temperature: Store the lobster in a low temperature environment, preferably close to freezing. Usually, refrigeration temperatures between 0-4 degrees Celsius will preserve the freshness of the lobster.

3.Humidity and ventilation: Lobsters need moderate humidity and ventilation to keep them moist and fresh.

To place the lobster in a breathable leather container covered with moist gauze or a damp towel.

Hello, if you want crayfish farming to live a little longer, you can do the following aspects of celery: 1. The site selection should be scientific and reasonable: the selected pond is close to water resources, the water quality is refreshing and zero pollution, the inlet and drainage pipes are convenient, and the first layer of soil is suitable for clay, and the permeability can be good.

2. Anti-escape facilities should be complete: crayfish have the growth habit of tracing water hit-and-run, and fence net anti-escape equipment should be set up around the pond, and at the same time, the inlet and outlet must do a good job in anti-escape work, and check it from time to time. 3. Reasonable stocking:

Free-range shrimp breeding is particularly important, and the success of stocking is equivalent to half the success of all stocking. Lobster seedlings should be selected without disease and injury, complete appendages, bright fish body color, and consistent specifications and models, and 50 high-quality juvenile shrimp of 200 per mu should be placed. If there is no self-propagating seedling, the basic principle of proximity principle acquisition should be used.

In the transportation, it can not be extruded and dried, and it is promoted a little more than a few times to ensure the survival rate of lobster seedlings. 4. Water quality management: Crayfish has strong disease resistance, most of them have no pests and diseases, and only have high requirements for the clarity of water quality.

Therefore, 50 100 flowers and silver carp can be quietly promoted per 667 square meters to control water quality. During the feeding period, it is generally sprayed with 10 15kg of quicklime powder every 667 days every 667 to facilitate the molting of freshwater lobsters.

Crayfish are relatively easy animals to feed, but there are a few things to keep in mind to ensure they can grow healthily and live a little longer. Here are some suggestions:1

Breeding environment: Crayfish prefer to grow in fresh water, generally choose a clear and pollution-free water environment, but also need to have enough water flow to provide oxygen and help clean the bottom of the residual food and dirt. At the same time, the water temperature is also important, preferably between 18 -24.

2.Food and nutrition: Crayfish like to eat vegetables, fruits and seafood, such as fish, etc., and need to ensure that they have sufficient nutritional intake to meet their growth and development needs.

3.Bottom Cleanup: Regularly wash the food and dirt left on the bottom to prevent this waste from rotting and polluting the water quality, while also providing a fresher environment for the crayfish.

4.Regular check-up: Observe the state of the crayfish, if you find abnormal phenomena such as slow action and loss of appetite, there may be certain health problems, and you should ask professionals for help and health advice in time.
