Is crayfish shelling an inevitable factor for growth? Farmers pay attention to the management of the shelling period to ensure stable production

farming of crayfish, it is far from enough to buy seed or cultivate seed for breeding at the right time. In addition to the basic preparations for aquaculture, such as the construction of clearing the ditch and disinfection of the rice fields, the preparation of water sources, and the preparation of natural baits, the farmers must also be familiar with the basic habits and breeding habits of crayfish. Understand what changes will happen to crayfish at different stages of growth and development, whether it is an inevitable or accidental factor.

The crayfish shelling described in this article is an inevitable factor . In our lives, everyone pays close attention to observation and finds that snakes, scorpions, golden cicadas, etc. will peel and shed their shells. This is a long-term behavioral change for animals to enter a new life. The shelling of crayfish is a necessary change in growth and development, and it will accompany a lifetime. So: why does

Crayfish

One: Shelling of crayfish is an inevitable factor for growth. During its shelling period, it provides the ecological environment needed for shelling to ensure the smooth shelling of

. Animal growth has its own behavioral characteristics and is also affected by ecological environmental factors. Crayfish is a crustacean, and only by constantly shed its shell can its body grow. Therefore, shelling is an important symbol of the growth and development of crayfish, and this symbol accompanies lifelong. Of course, crayfish shelling is affected by environmental factors, and only under suitable conditions can it be shelled smoothly. The conditions required for

are actually the changes in the living environment, such as :

Breeding base

2: Unsuccessful shelling is affected by ecological environmental factors, and water environment management must be strengthened, and daily feeding management must be strengthened.

The above mentioned simply that unsuccessful shelling will cause adverse effects, and unsuccessful shelling is not only affected by ecological factors. Also affected by factors such as bait and itself. Especially for large-scale farmers, it is necessary to know the reasons for unsuccessful shelling to avoid these phenomena and reduce losses. Water environmental factors of

Ecological environment

Crayfish spend their entire lives in the water and have a strong tendency to water. The calcium in the water, water quality, and water temperature directly affect their growth and development. Especially in the special period of shelling, the water environment of plays a direct role .

1. Crayfish are crustaceans and require a lot of calcium, especially during the shelling stage, they need to absorb a large amount of calcium, and these calciumThe element must be obtained from the water body, so the calcium element in the water must be sufficient. You can regularly splash lime water into the water during the growth period, or increase nutrition appropriately to enhance the physique of crayfish. The hulling period requires a quiet environment, and the best hulling should be carried out in an easy and short time to avoid being interfered by the same kind and enemies.
2. Although crayfish have strong adaptability to high water temperature and low water temperature, it is necessary to ensure the stability of the water temperature when shelling. Do not change the water during the shelling period to ensure that they can safely pass the weak period.
3. needs a low light environment, too strong light will make the crayfish feel insecure, so plant aquatic plants in advance so that they can hide when they are shelled.
4. Regularly change the water and sterilize the quicklime water to ensure a good water environment and reduce harmful substances in the water quality.

Strengthening the daily management of

The daily management of farmers is also an important factor, so you can’t "hold the slope foot temporarily"!

such as:

1. daily feeding should ensure balanced nutrition and strengthen the body.
2. Daily careful observation, it is found that the pests must be dealt with as soon as possible, so as to avoid the occurrence of lesions, causing the crayfish to be unable to shell.
3. Crayfish are sensitive to pesticides, so pay special attention to the water body not being polluted by pesticides.

Tips: Frozen three feet is not a day's cold. During the entire breeding process, strengthen management to find problems in time and deal with them in time. At the same time, they are familiar with the crayfish shelling time and make corresponding preparations to ensure the smooth shelling of crayfish .

Daily feeding management

Three: Strengthen daily aquaculture management, try to avoid a large number of soft-shell shrimp, to ensure a stable production

We sometimes find that there are some soft-shell shrimp, most of these soft-shell shrimp can not be hardened, so soft Shell shrimp is not only unable to prey, but also has no self-protection ability and is very susceptible to similar damage. Especially large-scale farming can easily cause great losses. Only by finding the reasons and strengthening management can the output be stabilized. The

soft shell shrimp is caused by chronic malnutrition, insufficient feed, aging water quality, excessive breeding density, calcium deficiency, or being parasitic by ciliates. Therefore, in daily feeding, not only must put enough food, but also have comprehensive nutrition. Change the water regularly to improve water quality. Sprinkle the hard shell treasure to add calcium to ensure that the crayfish can harden after shelling, and reduce the number of soft shell shrimps.

IV: Farmers should be familiar with the characteristics of crayfish shelling, and protect them after shelling to ensure their smooth and continuous growth.

must not only prepare before shelling crayfish, but also after shelling. Only with protection can the breeding efficiency be stabilized. Then you have to understand the time and characteristics of crayfish shelling.

usually patrols and finds empty shrimp shells, or eats a lot of food a few days before shelling, and basically eats little or no food for the next one or two days, indicating that crayfish need to shell a lot.

In addition, the shell of the shrimp is very hard before shelling, the body color is dark, and the feet are hard. In general, judges the crayfish's shelling time and law by looking at the eating condition, body color condition, and empty shell condition .

So how to protect the crayfish after they are shelled?

1. After shelling, crayfish are in the lowest resistance stage, basically there will not be much movement, so when shelling, it is necessary to provide suitable water temperature, concealed location and sufficient dissolved oxygen. The stocking density of
2. should be reasonable so that it will not cause crowding after shelling.
3. Maintain the palatability of the bait.
4. Keep the water environment quiet and low light.

After the crayfish is shelled, only after the carapace hardens in a suitable environment can it recover its normal resistance and protect itself.

Summary: The shelling behavior of crayfish accompanies the whole life, and each shelling indicates that it is growing and increasing. The shelling period of crayfish is the most vulnerable time in the entire growth and development cycle, and farmers should protect them during this special period. In daily feeding and management, it is necessary to carefully observe and provide comprehensive nutritional bait to ensure the healthy growth of crayfish. Only with a strong body can they have enough ability to shell, so as to breed high-quality and fertile crayfish and bring ideal economic benefits.
