First, the high-quality crab's back nail is blue-gray, shiny, the abdomen is white, the golden claws are clustered with yellow hair, the color is bright, the navel is round and protruding outward, the limbs are firmly connected in an arc shape, and it is large and healthy. If the back is yellow, the meat is thin. In addition, if the activity is strong, the crabs crawling around are strong and good crabs.

Second, for crabs that meet the requirements in appearance, they should be weighed by hand one by one, and the one that feels heavy is the fat crab. This trick is not suitable for river crabs and live sea crabs because these crabs are often tied up.

Third, peel off the umbilical cover of the crab. If there are many, neat and condensed crab roes in the shell, this crab is a good crab.

Fourth, if you buy a dead sea crab, you should observe the crab's legs, which are intact. Gently pull the crab's leg, which is weak in elasticity, indicating that it is a fresh sea crab. If it is not fresh, gently pulling the crab's leg is not only weak, but also easy to break.
