Crayfish growth cycle

The growth cycle of crayfish in natural environment is 6-12 months. In the case of artificial culture, the growth cycle is about 6 months. In addition, under the conditions of suitable temperature and adequate food supply, crayfish in crayfish can reach sexual maturity and meet the specifications of commercial shrimp after more than 2 months of culture.

High-yield culture methods of crayfish:

1. Culture pond selection

Select lakes, ditches, ponds or rice fields with a depth of 1-1.2m, an area of 3-5 mu and a pH of 6.5-8.5 as lobster culture ponds. Mud stalks are built in the middle of the culture ponds for crayfish to dig holes, ramps are built around to prevent crayfish from burrowing out, and anti-escape boards are built around the ramps of the culture ponds.

two。 Preparation before stocking

According to the ratio of 300-500kg per mu, base fertilizer is put into the culture pond, and aquatic plants are planted to provide habitat for crayfish.

3. Release of crayfish seedlings

Select the same size, healthy and dynamic crayfish seedlings, and put them in the proportion of 8-9 per square meter on a sunny morning or evening.

4. Crayfish feeding

Put the bait at 6-9 o'clock in the morning and 4-7 pm every day in the weather with the temperature above 20 degrees Celsius, and control that the quality of the bait put in the evening is 3-4 times that of the food put in the morning. T-ear food is put every day at 6-9 o'clock in the morning or 4-7 o'clock in the evening when the temperature is below 20 degrees Celsius.

5. Water body control of aquaculture pond

Change the water every half a month, changing 1/5 to 1/3 of the water volume each time.

Although crayfish is an "alien species", it is loved by the majority of diners because of its delicious meat. The current market demand is also relatively large, and the market situation is also very good, so crayfish farming is a good project choice.
