Why don't crabs eat in hot weather?

? Crab is a cold-blooded animal with variable temperature, and the suitable water temperature environment is 13℃~28℃. When the temperature is higher than 28℃, the crab will reduce its food intake and be in a coma, maintaining its basal metabolism to avoid the high temperature. This is also the genetic instinct of crabs to adapt to the environment.

Stopping growth in high temperature season in July and August is also the main reason for the early introduction of southern crab seedlings, but the specifications are not much different from those of northern crabs after recapture in autumn.
