Often, the crayfish will not perform a tail flip in this situation. This is because when a crayfish is actively feeding, the LGI itself is modulated by the behavior.
Crayfish can be cooked more humanely by first freezing them unconscious for a few hours, then destroying the central nervous system along their abdomen by cutting the crayfish lengthwise with a long knife down the center of the crayfish before cooking it. [46] Global crayfish production is centered in Asia, primarily China.

Big Sandy crayfish are opportunistic omnivores, as they eat both living and dead plants and animals available in their habitats.They act as an important link in the food chain of their ecosystem, as they eat a wide variety of decaying and living small organisms and are then eaten by predators including mammals, sport fish, reptiles, birds, and amphibians.
The report assumes that the violent reaction of lobsters to boiling water is a reflex response (i.e. does not involve conscious perception) to noxious stimuli. [ 3 ] A European Food Safety Authority (EFSA) 2005 publication [ 82 ] stated that the largest of decapod crustaceans have complex behaviour, a pain system, considerable learning ...
