How to feed small crabs, how to raise small crabs

Breeding environment: choose deep storage boxes, glass fish tanks, etc. as breeding sites, and build pools, dry land and sheltered areas in them. Feeding and feeding:

Regularly prepare concentrated food such as corn flour and rice bran for small crabs. Water quality requirements: Change the clean water for the small crabs every 15 days to ensure that the water quality is clean and hygienic.

2. Feed feeding

In the process of breeding small crabs, it is necessary to keep the water temperature above 10 degrees, and regularly provide them with corn flour, soybean meal, rice bran and other concentrate feed-based food, after the temperature rises in summer, to provide plant feed for crabs, and provide animal feed such as fish and shrimp and screws during the fattening period.

3. Water quality requirements

Small crabs have higher requirements for water quality, and the water quality should be checked and replaced regularly during the feeding period, generally every fifteen days to change the clean water, and add water to the small crabs in time to keep the water depth stable, the water quality is clean and hygienic, and the male crabs and female crabs should be cultivated separately.

Small crabs should be fed from the requirements of the breeding pond, keeping the pond clean, releasing seedlings, water quality control, crab disease prevention and control, etc.

1. Requirements for breeding ponds: small crabs like to grow in an environment with sufficient water sources and clean water, so it is best to choose a pond that is far away from the city and surrounded by pollution-free places for breeding.

4. Water quality control: When crab breeding is carried out in the pond, the water quality used should be very high. It is necessary to disinfect the pond water, and by using bleaching powder to disinfect the pond with drugs, it is necessary to ensure that the water quality is clean and avoid water quality problems.

5. Prevention and control of crab diseases: The prevention and control of crab diseases should adhere to the principle of prevention, so as to achieve early detection, early prevention, and early treatment of diseases. Different approaches to prevention are taken at different stages of growth.
