How to feed brown crabs after buying them home, brown crabs can be artificially farmed

Buy a tall plastic bucket and put the crabs in it, if you are afraid that the crabs will crawl out, buy a lid with a hole to seal the bucket, so that it is foolproof, remind: it is best to decorate the water, buy some dried shrimp for the crabs to eat, and change the water once every 5 days.

Brown crabs can be farmed in captivity.

Brown crab mostly refers to the species of the genus Zodiac Crab or the genus Mantou Crab. Brown crabs are mainly found in the Pacific Ocean and can also be found in Hong Kong waters. Artificial farming reduces costs, but is certainly slightly inferior to wild-caught in taste.

Breeding conditions:

1. Water temperature: the tolerance temperature range of brown crab is 3 23, the suitable temperature for breeding is 10 20, and the water temperature of 14 19 grows faster, and the optimal breeding water temperature is 15 18.

2. Salinity: The adapted salinity range of brown crab farming is wide, with a tolerant salinity range of 12 40, a suitable salinity of 20 32, and an optimal salinity of 25 30.

3. The light of brown crab should not be too strong, 500 1500 lux is appropriate. The light should be even, soft, not dazzling, and comfortable. The rhythm of light is the same as that of natural light.

1. How to buy live brown crabs and store them at home: first put the shrimp and crabs in pots, jars and other containers, spread a layer of mud on the bottom of the container, and then put some sesame seeds or beaten eggs in a cool place. Sprinkle some water on the shrimp and crabs every once in a while to keep them hydrated.

And don't release the crabs with a lack of straps, they will die if the stagnant water lacks oxygen. If it is kept refrigerated, you need to cover them with a damp towel and let them keep it moist.

2. Brown crab, a species of polydactyly, subphylum crustaceans, decapods, zodiac crabs or steamed crabs. The breastplate of the head of the brown crab is light brown; eye area with half-annular russet markings; chelicerae ankle and lateral surface of long segment with a russet spot; The tips of the feet are brown. The male cephalothorax is 62 mm long and 83 mm wide; The female cephalothorax is millimeters long and the nails are millimeters wide.

1. Water temperature: the tolerance temperature range of brown crab is 3 23, the suitable temperature for breeding is 10 20, and the water temperature of 14 19 grows faster, and the optimal breeding water temperature is 15 18.

2. Salinity: The adaptation salinity range of brown crab farming is relatively wide, the salinity range of the tolerant circle is 12 40, the suitable salinity is 20 32, and the most suitable salinity is 25 30.

3. The brown crab light hall collapse should not be too strong, and 500 1500lux is appropriate. The light should be even, soft, not dazzling, and comfortable. The rhythm of light is the same as that of natural light.

How to preserve brown crab.

Method 1. First, prepare a foam box that is the size of the freezer compartment of the refrigerator, then tie the legs and feet of the brown crab and put them tightly into the foam box one by one, and then add water from the surface of the brown crab to the box. Finally, cover the foam box and put it in the freezer compartment of the refrigerator, so that the brown crab can survive for a while without dying.

Method two. Keep the brown crab in a bathtub, pour water just past the brown crab so that it can breathe when it stands up, and put a small amount of small fish and shrimp in the water, so that the brown crab can live for a week or more without dying.

Method three. If Duan Peiguo does not have a bathtub at home, you can put the brown crab in a plastic bucket or basin with a higher and smooth inner wall, add water to half the height of the brown crab, and you can't bury the brown crab all over the year, and it can't breathe when the limb is open, and then put a small amount of small fish and shrimp in it, so that the preservation can make the brown crab temporarily immortal, and it will slowly die after surviving for a while.
