I want to breed swimming crabs. What conditions are needed to breed swimming crabs?

Swimming crab is another name for white crab. Because its body shell looks very similar to that of a swimming crab, it is called swimming crab. The meat of swimming crab is plump, delicious and has high nutritional value. It is widely distributed in various coastal cities and is a common food for people in coastal areas, but it is difficult for people in inland areas to eat it. Therefore, more and more people are starting to engage in large-scale breeding. How should swimming crabs be bred? Let's take a look below!

1. Prepare the pond in advance

Swimming crabs are marine creatures, so the water quality requirement is that they must be saltwater. You should choose an area with abundant water resources and clean water quality without pathogens. It is best to have sufficient miscellaneous fish and shrimps, because it can provide sufficient natural food for swimming crabs. There is a good irrigation system, which is convenient for changing the water in the fish tank. Swimming crabs like to rest on the shore, so there should be enough open space around the pond for swimming crabs to rest, preferably with a steep slope. Put appropriate fine sand in the pond to meet the swimming crabs' preference for lurking in the sand. The pond water should not be too deep, 4-6 meters is enough.

2. Prepare for work

Before stocking crab seedlings, drain all the water, clean the pond, and sprinkle lime powder all over the pond for disinfection to eliminate the original pathogens and prevent crab seedlings from getting sick. Remove the sludge in the pond, but not too much, just a little. Then loosen the remaining sludge and expose it to the sun for 3-5 days before stocking. Pay attention to setting up oxygen, irrigation and cannon equipment in the pond, and make all preparations. A certain number of empty bottles, water pipes, etc. can also be placed in the regulating pond to let them rest. Before stocking, apply appropriate fertilizers to the pond to cultivate sufficient plankton. Fertilizers should not be too much, otherwise the water quality fertilizer effect will be too large, which will harm the growth of crabs.

3. Crab seedlings stocking

After all preparations are done, start stocking crab seedlings. The crab seedlings stocked in the same pond should be of the same size. Different sizes are prone to large ones bullying small ones, affecting the survival rate. The stocking density should not be too large. The total number of crabs stocked per mu should not exceed 3,000, otherwise there will be competition for food among crabs, fights, etc., affecting the growth and survival of all crabs. But it should not be too sparse. Too little will reduce the charm of crabs and easily affect the water quality. Feed concentrated feed on time, the temperature during stocking should not be lower than 20 degrees, and the temperature should be controlled at a constant speed to effectively improve the survival rate.

4. Daily management methods

In summer, you should pay attention to the changes in water quality in time. You should change the water at least three times a week. The frequency of changing water in the fish tank is determined by the temperature changes. The water change rate must be determined according to the water quality and the growth of the crab. Swimming crabs are very carnivorous. They can be fed with fish, shrimps, shellfish and other small animals. They should be fed at least twice a day. When the temperature drops to ten degrees in winter, they do not need to be fed. Because the lower the temperature, the worse the appetite of swimming crabs. They will not eat at all when the temperature is below ten degrees. During breeding, you should inspect frequently, observe the water quality and growth status, change the water and add oxygen to the fish tank in time, and catch sick crabs immediately for inspection and proper treatment.

The above is a brief introduction to swimming crab farming. The total area for swimming crab farming is not large, because the first requirement of salt water has kept most people away. However, it has attracted many people to go to coastal areas for farming, and the market for swimming crabs is now in a tight situation. Therefore, there is still a certain market prospect for farming. If you have the conditions, you can contract a piece of land on the seaside for farming. The article is for reference only, and I hope it will be helpful to us.

A spacious breeding site is needed, and salt water is needed, because this kind of crab grows in the ocean. The water quality needs to be relatively clear and pollution-free. Not too much water should be added. Disinfection should be done regularly, drainage measures should be taken, and suitable feeding and transportation feed should be selected. The water temperature should be kept at no less than 20 degrees all year round.

You must choose a large environment, preferably about 15 acres, you must choose a place with abundant water resources, the pool must be made deeper, and the base must be free of any pollution, and it is convenient for drainage and water inlet.

1. Prepare a shallow pond without pollution. The water where swimming crabs like to live should not be too deep. 2 Leave some land, as they like to bask in the sun. 3. Adjust the water temperature according to the weather.

Are swimming crabs mostly farmed or wild? Which season is the fattest?

1. Swimming crabs are abundant in summer. Most of the swimming crabs on the market in summer are wild. After summer, there are more farmed crabs. 2. Swimming crabs are plump from August to November. 3. Wild swimming crabs have harder shells and stronger legs. Farmed swimming crabs have thinner shells and average leg strength. 4. The belly of wild swimming crabs is shiny and glossy. The belly and joints of farmed crabs will show signs of blackening.

1. Are swimming crabs mostly farmed or wild?

1. Are swimming crabs mostly farmed or wild?

There are both wild and farmed swimming crabs on the market, depending on the season. Generally, swimming crabs are abundant in summer, and there are more wild ones on the market. After summer, there are more farmed swimming crabs.

2. The difference between farmed and wild swimming crabs

(1) Housing

Wild swimming crabs are more active, so all parts of their bodies grow stronger, their shells are harder, and their legs are stronger. Farmed swimming crabs have no natural enemies, so they are less active, their shells are thinner, and their legs are average.

(2) Belly

The belly of wild swimming crabs looks shiny and glossy, with less mud and sand in the body. The belly crevices and claw joints of artificially cultivated swimming crabs will show signs of blackening.

(3) Crab legs

The legs and claws of wild swimming crabs are more active and longer, while the claws and legs of artificially cultured swimming crabs are slightly shorter.

(4) Taste

The meat of wild swimming crabs is whiter, tenderer and more delicate than those farmed ones, and their flavor is also stronger.

2. When are swimming crabs fatter?

1. The season of plump swimming crabs begins

The swimming crab is in its fattening period from August to November and is relatively plump.

2. How to choose swimming crabs

(1) Pinch the crab shell to see if the crab will release water. A crab that releases a lot of water is usually weak and heavy, not really fat.

(2) Pinch the crab’s middle leg with a little force. If you feel the muscles contract, it means it is a fat crab.

(3) If the back of a swimming crab is green and hard, it means that the crab is fatter and of higher quality.

(4) Check whether there is yellow-red substance on the tips of the two edges of the crab shell. The more red the substance, the yellower the surface.

(5) Turn the crab belly upwards and look at the color of its horns. If there is more white, it is fat; if there is more gray, it is C.

(6) The belly button of a crab is usually light red. The more red it is, the fatter the crab is.
