|Stunning and Killing Methods||Species||Signs of Pain and Distress||Suitable for Humane Slaughter|
|Electrical stunning||Lobster, Crab||None||Yes [64,65,66,69]|
|Chilling||Large crustaceans||No behavioural signs of distress but a long time to death. Not suitable as calming before boiling.||No * |
|Carbon-dioxide (CO2) narcosis||Crab||Aversive behaviour (tearing at their own sternums with their chelae, exposing internal organs) and autotomy.||No [48,63,66,67]|
|High-pressure killing||Lobster, Crab, other decapods||More information on the speed of killing and possible suffering are required for a better evaluation||Possibly [69,76,77]|
|Drowning||Saltwater species||Aversive behaviour (uncoordinated bodily movements and increased intensity of respiration) and autotomy||No |
|Salt baths||Lobster||Abnormal behaviours (retraction of the antennae, stillness, and feeble locomotion in some cases)||No |
|Boiling||Crab, Lobster||Physiological shock and autotomy||No [2,67,71]|
|Dismemberment||Lobster, Crab||Markedly decreased ability to feed, rapid stress response||No [32,40,80]|
