Crabs can grow back their claws.
Something I didn't know and now wish I didn't.
Unfortunately this means that fishermen in the US, Europe and the UK (fishermen there can legally take both claws) can de-claw their catch, throw them back into the sea to regenerate the claws, to be caught and de-clawed again in a never ending cycle.
This is considered a sustainable industry.
Bob Elwood and colleagues of Queen's University, Belfast, UK, measured how much de-clawing increased stress and affected the crabs survival.
Crabs with one claw removed showed a greater physiological stress response than crabs allowed to shed a claw naturally. And they were still stressed 24 hours later.
Of 28 crabs that had one claw removed, 5 died.
No crabs died after shedding their claws naturally.
What this news snippet didn't say was where or how the researchers got their data.
On a fishing boat - doubtful. In the laboratory - more likely.
So is it creepy that they de-clawed crabs and watched what happened or should I put this down to a 'Star Trek' moment where the needs of the many (un-de-clawed non stressed crabs) take precedence over the needs of the few (de-clawed stressed outs).
