How to judge whether a crab is alive or dead, and how to see whether a crab is alive or dead?

If you want to judge whether a crab is alive or dead, you can smell it first. The living crab smells fishy, while the dead crab smells bad. You can also look at its eyes, the eyes of live crabs will move. If you pour a little water on the crab's body, if it is still alive, its mouth will move, and the dead will not react. After untying the rope and putting it at room temperature, it will crawl after a while.

1. Smell the smell

The most direct way to judge whether a crab is alive or dead is to smell it.Whether sea crabs or river crabs, there will generally be a fishy smell, which is inevitable, but the dead crabs have begun to decompose and rot, so there will be a little odor, this odor can not be covered up, so it is easy to smell out.

Two, look at the eyes

The dying crab may not be energetic, or because the body is tied up and can not move, but its eyes can move.Observe its eyestalk, or directly touch some, live crabs can move autonomously, while dead crabs eyes will not move, this method of judgment is more accurate.

Three, pour some water

Crabs breathe with gills, which may not be obvious in the air, but as long as there is water, it is easy to see.Pour a little water on its mouth, if it is still alive, it will open automatically, if it is a dead crab will not respond.In addition, live crabs will spit bubbles when they breathe.

IV. Untying the Rope

Generally, the crabs bought are tied up with ropes. In this case, its activities are limited. In addition, the cryopreservation causes it to be dormant, so it is not easy to say whether it is dead or not.You can put it in room temperature environment, and untie the rope, wait a moment to see if it will crawl, the living will generally move.
