What conditions are needed for crayfish farming?

Crayfish meat is tender and plump, and whether stir-fried over high heat or steamed, it has a distinctive flavor. It is now the season for eating crayfish, and whether at late-night food stalls, restaurants or people's homes, everyone has recently been ordering this delicacy, crayfish. Because crayfish prices have plummeted, from 20 to 30 yuan per jin in May down to 10 yuan per jin, everyone has been buying them to try. Crayfish farming has good economic returns, and various green farming models are deeply favored by farmers. So, today let us take a look at what conditions are needed for farming crayfish?

1. Requirements for the farming environment

Crayfish grow better in dim environments and are especially afraid of strong light, so they are usually active by night and rest by day; even during the day, they hide in dim places. Crayfish have very strong legs and often dig burrows, so they generally dig burrows relatively close to the water. If a large number of crayfish gather in one place to dig burrows, it will cause some damage to the farming environment, and then the crayfish will all escape together. Therefore, when establishing a crayfish farming site, an anti-escape net must be added around the perimeter to prevent the crayfish from escaping. In addition, to let the crayfish grow better, the water surface of the farming pond should be made to simulate the living environment of aquatic plants, providing hidden objects so that the crayfish have places to rest and molt, thus avoiding the phenomenon of them killing each other.

2. Key points of water quality management

Crayfish farming has relatively high requirements for water quality. No matter what aquatic animal is being farmed, water quality will affect its normal growth, and crayfish are the same. Therefore, weakly alkaline pH is relatively suitable for crayfish growth. Normally, water changes and water addition should be done regularly, and some natural plankton should be cultivated as crayfish feed. When managing water quality, limewater disinfection measures should be carried out regularly to avoid too many microorganisms in the water causing crayfish diseases.

3. Scientific feeding

Crayfish feeding must be scientific, and the amount must be controlled well. If feed is insufficient for a long time, crayfish may fight for food and even kill each other. Therefore, when feeding, they must be guaranteed to eat their fill. As omnivorous aquatic animals, crayfish have many feed choices; for example, animal-based feeds include livestock and poultry offal and trash fish, while plant-based feeds include aquatic plants, rapeseed cake, wheat, and so on. Feeding is generally carried out in the evening, which is also determined by the living habits of crayfish.

4. Catching crayfish

If farming is done properly, and young crayfish grow normally with sufficient feed and suitable temperatures, they can generally be caught and sold in bulk after two or three months. When catching crayfish, attention should be paid to keeping the small ones and catching the large ones, and rotating stocking and replenishing, so that the recapture rate can be increased and a good price can be obtained.

In summary, crayfish farming must pay attention to details such as the farming environment, water quality, feeding, and catching, so that a bumper harvest can be obtained.
