Aquatic Crustaceans Caught and Used for Food
SPCA advocates that wild, aquatic crustaceans, including crayfish, crabs, and lobsters, caught for food must be treated humanely at all times.
Crayfish, crabs, and lobsters are considered sentient under the Animal Welfare Act and are capable of experiencing both positive and negative emotions, including pain and distress. This places a duty on humans to ensure that we treat crustaceans humanely.
SPCA opposes subjecting live wild crustaceans to welfare harms during transport.
SPCA is concerned about the welfare impact of exporting live rock lobsters, including whether shipping conditions such as chilling or use of AQUI-S minimise welfare harms during transport.
SPCA advocates that crustaceans only be killed after they have been humanely stunned.
It is an offense under the Animal Welfare (Care and Procedures) Regulations 2018 for a person to kill a crab, rock lobster, crayfish, or koura for commercial purposes unless the animal is insensible before killing. However, this does not apply to an animal captured in the wild for the purpose of facilitating imminent destruction. SPCA advocates that all aquatic crustaceans be stunned before killing.
Electrical stunning devices or anaesthetics (such as AQUI-S) can be used to humanely stun and kill crustaceans. Electrical stunning can humanely kill crustaceans at high enough voltage/concentration or can humanely stun crustaceans at lower voltage/concentration. If the animal has only been stunned with an electrical stunning device or anaesthetic, a mechanical method of killing that destroys the crustaceans’ chain of ganglia (their central nervous system), such as splitting, must follow immediately.
SPCA opposes the use of inhumane methods to stun or kill crustaceans.
Spiking and splitting alone, and high pressure killing of conscious crustaceans does not lead to immediate death and these methods are likely to cause distress. Crustaceans must never be gutted, frozen or subjected to any other form of processing whilst still conscious. It is not humane to boil crustaceans alive. In addition, chilling in air or on ice, boiling, gassing with carbon dioxide, or “drowning” in fresh water are not humane methods of stunning or killing crustaceans.
