The distributed brain centres (ganglia) and heart locations on a
typical lobster (top) and crab (above). Crustastun passes a current
through the ganglia, stunning the animals almost instantly.
The lobster or crab is stunned into unconsciousness in less than half a second. In just five
seconds, a lobster, langoustine or crayfish will be dead, while a crab takes ten seconds to
die. By comparison, it takes two to three minutes to kill a small lobster in boiling water, or
up to ten minutes for a crab.
It has been scientifically established that a current of 1–1.3 amps is required to stun a
lobster, crayfish or crab into unconsciousness, and that maintaining this current for five to
ten seconds will kill it.
At the touch of a button, Crustastun passes a typical current of 4–6 amps, instantly stunning
and then killing the animal, so that it can be cooked without unnecessary suffering. This
process has been shown to improve both the texture and the flavour of lobster and crab
meat, because it inhibits the production of stress chemicals.
Electro-stunning also kills harmful bacteria and significantly delays spoilage.
SIGNS OF EFFECTIVE STUN
• The animal is stiff at first and becomes limp after a few minutes.
• Some of the mouth parts and swimmerets may twitch following the stun.
• The eyes are limp and do not react to touch.
Immediately after an electrical stun, the crustacean enters what is scientifically termed as
the tonic phase, during which it remains completely stiff and all respiratory movements
cease. After two to three minutes it becomes limp.
Owing to the residual energy left in the muscles of the animal, random movement may
sometimes be seen, although the animal is actually brain dead. This is particularly the case
in lobsters, where there can be fibrillations – especially in the mouth parts and swimmerets
along the underside. This is normal. If the eyes are unresponsive to touch, the creature has
been effectively stunned.
HOW CRUSTASTUN WORKS
The Crustastun electro-stunner is the only
machine specially designed for the quick and
compassionate stunning of crabs, lobsters
and other shellfish. It is now scientifically
accepted that decapod crustaceans such
as lobsters, langoustines, crayfish and crabs
can experience pain and distress. Traditional
killing methods involve the cooking and
butchering alive of these sentient animals.
The electro-stunning method used by
Crustastun is based on research carried out
at the University of Bristol, UK. Crustastun
applies a small
instantaneously through the 13 brain centres
(ganglia) of a lobster or lobster-type animal
such as a langoustine or crayfish, or the two
brain centres of a crab.
