How to raise hairy crabs at home
Mid-autumn, full moon people gather, crab fat flowers, is a great beauty of life. Eating crabs under the osmanthus tree to enjoy the moon has been respected by literati since ancient times. Now what we want to talk about is the crabs in the beauty of life. How to raise the fine crabs at home-hairy crabs?
The meat of hairy crab is delicious, rich in protein, less fat and carbohydrates and rich in trace elements. The content of cholesterol in crab roe is high, so it is a favorite aquatic delicacy on the dinner table. It has high edible value, medicinal value and economic value.
When hairy crabs are bought and cannot be eaten in time, there are generally three ways to cultivate and preserve them.
1. In captivity in the sink. If you buy hairy crabs that need to be preserved for 3-5 days, you can use a deeper sink at home or a larger and deeper plastic bucket for breeding. First of all, gently pick up the hairy crabs in the sink and other containers and put them in clear water (tap water is recommended to dry for 2 hours). The depth of the water should not be too deep, so that the hairy crab can stand up and breathe on the surface of the water. If the storage time is long, it is recommended to put a small amount of fish and shrimp in the water.
two。 Plastic buckets in captivity. Use a 30-50cm high plastic bucket / basin, put the hairy crabs flat in them, and be careful not to let the crabs stack up. Then add water to half the height of the hairy crab, and remember that the depth of the water can not pass all the hairy crabs. Do not cover the bucket or basin, put it in a cool, ventilated place.
3. Keep it in the refrigerator. Choose energetic hairy crabs and tie up the feet of hairy crabs to reduce physical exertion. Choose the ones that are not active enough to eat every day, and the hairy crabs with enough vitality can continue to be preserved. Keep it in the freezer and keep the temperature at 5-10 degrees. Cover the crab with a wet towel to keep it humid.
As long as there is a way to breed hairy crabs at home, hairy crabs raised at home for a long time will reduce their vitality and delicacy after cooking. After buying hairy crabs, people should eat them as soon as possible.
