Green crabs put in the refrigerator overnight dead, can eat depends on the situation to decide. As follows:

1, freezer: can not eat.

The temperature of the refrigerator freezer is about 3-10 degrees. At this temperature, green crabs can easily die, but the ambient temperature of the post-mortem storage is not high enough to inhibit bacterial reproduction for a short period of time. However, one night is too long. Generally speaking, green crabs that have been frozen to death in the refrigerator freezer for 3-4 hours can be eaten, but more than one night will harbor more bacteria.

2. Freezer: edible.

If live green crabs are stored directly in the refrigerator's freezer, because the temperature in the refrigerator is lower, it is difficult for bacteria to reproduce and multiply. The edible period of green crabs can be kept longer. If they die after being frozen overnight, they are still edible. At this point, the flavor and meat quality of frozen green crabs have not changed much, so they are safe to eat.

Life habits of green crabs

As a burrowing aquatic crustacean, the green crab prefers to inhabit intertidal sandy beaches, mangrove forests or marshes, burrowing in its burrow during the day and coming out to forage for food at night. Green crabs are agile and have very sensitive sensory organs.

In summer, it likes to support its body with its feet in the high tide zone, and in low temperature, it lurks in the mud and sand with only its eyes exposed. As a widely saline species, the green crab can grow normally under the salinity condition of 5-33‰, and the suitable growth salinity condition is 14-27‰.
