When is the best time to raise crayfish? What aspects should be paid attention to when breeding? These five points are very important!

In recent years, crayfish appear more and more frequently on the dinner table, crayfish farming is becoming more and more common, and its profits are relatively high, so many farmers are flocking to it. When is the best time to raise crayfish? What aspects should be paid attention to when breeding? These 5 points are important!

When is the best time to raise crayfish

Every year, March and April is the most critical period for crayfish farming, because this is when shrimp seedlings are released. Crayfish can be caught when they are released from March to April and reach about 40 grams each from June to July. At present, Sichuan, Hunan, Hubei, Jiangsu, Zhejiang, Guangdong, Guangxi, Anhui, Yunnan and Guizhou are the main producing areas of crayfish in China.

What aspects should be paid attention to in crayfish culture

1. Prepare

Novice farmers need to learn more and visit more, learn theoretical knowledge and listen to the experience of old farmers. Shrimp fry, water quality, feed, diseases, and so on, should be learned to reduce the risk of farming failure.

2. Seed selection

At present, there is only one species of crayfish in China, that is, the scientific name we usually see is called Procambarus clarkii. Anyone who asks for a high price under the banner of a new breed of crayfish must be a hoax.

3. Purchase seedlings

The principle of proximity should be adopted in the purchase of shrimp seedlings. The normal transportation time is no more than two hours. It is best to use the direct door-to-door purchase of farmers, and try not to go through hand-to-hand intermediaries. Transport, low-density loading, the bottom covered with water plants, handle gently.

4. Release seedlings

When putting in shrimp seedlings, the specifications of shrimp seedlings should not be too uniform, otherwise it will sometimes lead to the phenomenon that shrimp seedlings do not grow up when the price is high, and the price begins to go down again. And after the shrimp seedlings of uniform specifications grow at the same time, it will cause excessive pond load, ecological collapse and other phenomena, but the phenomenon of crayfish killing each other has little to do with the differences in specifications.

5. Management

Crayfish are aggressive by nature and have a strong habit of occupying land. If there is no space or shelter for them to hide, it will lead to serious killing each other. When breeding crayfish, some water plants such as hyacinth can be planted in the water, which can also be used as food for crayfish at the same time.

III. Prospects of crayfish culture in 2020

Judging from the market rules of the past few years, the price of lobster was relatively high when it was first listed on the market, and declined relatively when it was listed in May and June. After August and September, the volume of the pond was less, and the price rose again. Moreover, in recent years, the demand for lobster in the domestic market is very strong. In large and medium-sized cities such as Wuhan, Wuxi, Nanjing, Changzhou, Suzhou, Huaian, Shanghai and Hefei, the annual consumption of lobster is more than 10,000 tons. Strong consumer demand provides a broad development space and potential for the development of lobster aquaculture, so the development prospect of lobster farming is broad.

Although crayfish farming is profitable, it is best for farmers to improve the quality of lobster in order to have a better place in the market.
