Raised in seawater, or in ordinary water.
Add sea salt and then oxygenate.
Water pump, so that there is no lack of oxygen in the water, so that it can be fed.
-
Crabs in the sea will soon be deprived of oxygen and die when they are brought to the house, because once the crabs in the sea leave the environment in which they live, there is no way to survive for a long time.

1.Prepare the container: Prepare a water basin about 50 cm deep and 40-50 cm wide as a feeding container, and spread a layer of sediment at the bottom of the water basin.
2. Change the water in time: use seawater to raise sea crabs, and change the water once every 5 days to ensure that the water quality is clean.
3. Feeding food: During the feeding period, regularly feed fresh and tender fish and shrimp, or soybean flour, rice and other foods.
4. Feeding management: put the sea crab in a cool place and clean up the food residue on time every day.

The cultivation of sea crabs requires salt farming, and go to the market to buy sea salt for special breeding to prepare. It can also be cultivated directly from mariculture. The water temperature should be above 18, the daily temperature difference should be less than 8, the salinity should be 18 32, the pH should be less than 1 mg l of ammonia nitrogen, the dissolved oxygen should be greater than 5 mg l of water, and the transparency should be kept at 30 40 cm.
In order to survive, sea crabs must have a large amount of sodium ions in the water, and on the other hand, due to the high permeability of sea crabs themselves, it is easy to cause the death of sea crabs due to changes in pressure if they are directly put into fresh water for breeding.

Sea salt can be mixed with water, never salted tap water. And before using sea salt water, you need to put the water in the sun for one to two days, otherwise it can easily lead to poisoning. Secondly, when raising baby sea crabs, you need to put stones, sea sand and aquatic plants in the fish tank, and then place the fish tank closer to the window, but avoid exposure to the sun.
In addition, it is necessary to change the water frequently to prevent the growth of bacteria.

It is not easy to raise sea crabs at home, because they need seawater to adapt, and they cannot use edible salt to configure seawater, so they must be washed into seawater to raise them. Raising crabs is not necessarily changed in water, generally changed once every 2-3 days in summer, and the water should be exposed to the sun for a day.

If there is no seawater at home, how can I raise sea crabs? You can put less salty salt in the water, and the water will have a bit of a salty taste, and you can raise sea crabs.

Sea salt is on the line, two yuan is a big bag, salt is not good for crabs, you need to use breeding salt, the aquarium store may sell it.
-
There is no seawater at home, so if we want to breed these sea creatures, we can put some experiments at home into some environments that simulate seawater. For specific how, there are tutorials on the Internet, you can check it.
-
You can buy seawater medicine to raise.

How about sea crabs without seawater at home? Hey, when it comes to seafood, he'll give you something to raise sea crabs. You're worried about this.

You can go to the beach and load seawater
-
Then you can't raise it, there is no condition for raising sea crabs, and I'm really helping you look forward to it

You can raise it in a basin, it doesn't matter if the water is deep or shallow, it won't drown it. However, it is better to have water freshly soaked in the shell. You can let it bask in the sun, don't bask it for too long. You can use tap water for water, but you don't need to use it until you dry it for a day.
Crabs are omnivorous.
You can feed them fish, whether it's raw or dried. They may also be fed fish feed, bloodworms, dried shrimp, snails, mussels.
It is best to feed some grass-based foods frequently, such as bitter grass, eloso, etc.
As long as the feeding is OK, there is no need to worry about the rest. Crabs are easy to raise.
To add salt, add 1 liter to 2 level tablespoons of salt.

<> vast majority of species of crabs live in the sea or in the offshore areas of Yuanhui, but some inhabit freshwater or land. Can the crab be fed by itself?
OK. Use a large fish tank or a deep container, put fine sand and stones at the bottom, and then put in the dried tap water, and plant some aquatic plants to create a good environment for the crabs. Put in healthy crabs, feed egg yolks, small fish, small shrimp, snails, etc., feed 1-2 times a day, and take them out in time if you can't finish eating.
Change the water every three days and keep the water clean.
Live crabs are placed on the insurance floor, and they can be raised for a month.
Raising crabs at home can feed them bread worms, fish and shrimp, bloodworms, earthworms and cabbage. Its feeding habits are more mixed, mainly eating aquatic plants, benthic animals, organic detritus in the wild, and the temperature must be controlled when raising, and the water temperature should not be too low.
Today I would like to share with you the maintenance and management skills of orchids.
