CATDOLL : CATDOLL: How to farm crabs?

1. Pond Preparation

The breeding pond should be located in a place with abundant aquatic plants, clean and clear water, and plenty of sunshine. Anti-escape equipment should be installed around the pond to reduce the incidence of disease during the breeding process.

2. Seed selection and seedling planting

When releasing crab seeds, the crab seedlings should be temporarily raised for a period of time. In order to allow the crab seedlings to have a transition period of adaptation, a temporary raising area should be set up in the pond. Pay attention to the stocking density, which should be moderate to ensure the normal growth and development of river crabs. The stocking time is generally around the beginning of spring.

3. Feeding

After stocking crabs, when the water temperature in the pond reaches 11 degrees or above, they need to be fed manually. After August, it is necessary to increase the amount of animal meat fed, the main purpose is to promote the gonadal development of river crabs and increase the weight of river crabs.

4. Water quality management

When stocking crabs, it is necessary to ensure that the water has a certain amount of fertility and that the fertility cannot be reduced, so water should be added at least once a week during the breeding process. It is not necessary to change the entire pond water each time, but only about 30% of the water can be changed. Quicklime should also be sprinkled regularly, about once every 15 days.

Additional information

To breed crabs, you need to first clean and disinfect the pond, then release the crab seedlings and feed them in a timely manner.

The crab's body is divided into the cephalothorax and abdomen. The back of the cephalothorax is covered with a cephalothorax, the shape of which varies from species to species. The first and second pairs of antennae are located in the center of the forehead, and the outer side is a stalked compound eye. The mouthparts include a pair of mandibles, two pairs of maxillae, and three pairs of maxillopods.

There are 5 pairs of thoracic legs on both sides of the cephalothorax. The abdomen is degenerate, flat, and zigzag on the ventral surface of the cephalothorax. The abdomen of the male is narrow and long, mostly triangular, with only the first two pairs of appendages transformed into copulatory organs; the abdomen of the female is broad, with a pair of double-branched appendages on the 2nd to 5th segments, densely covered with bristles, used to hold eggs. Most crabs are marine, with the most species in tropical shallow waters.
