Crab is a kind of common crustacean, they can breed.Because crabs live in water, we need to pay attention to the problem of water use in the process of breeding.The crab divides into the fresh water crab and the sea crab two kinds, they distribute the water area is different, adapts the environment is also different.The former is suitable for living in fresh water, while the latter lives in seawater and adapts to the marine environment.
Therefore, it is necessary to prepare water according to the habits and characteristics of crabs.For freshwater crabs, they can be raised directly from river or lake water, or directly from tap water at home.Of course, the direct use of the tap water from the faucet is not feasible, it is best to dry it, after a day in the sun can be used.There are many kinds of freshwater crabs, such as Chengyang Lake hairy crab, crystal crab and red star swimming crab.Then there are sea crabs, such as flower crabs, green crabs, rising crabs and so on, these crabs can not be cultured in freshwater, because they can not adapt to the freshwater environment, so they need to simulate the seawater environment, at this time they need to use brackish water.
As mentioned above, crabs are divided into two varieties, one is freshwater crab, the other is sea crab, and the requirements of these two kinds of crabs for living environment are different.For freshwater crabs, they can naturally adapt to freshwater environment and can be cultured in freshwater.However, for crabs that originally live in the ocean, they can not be cultured with fresh water, and they generally can not adapt.Therefore, it is better to breed them in brackish water, and at the same time, we need to pay attention to the depth of water, we can use slightly deeper water to breed them.
