On the seawalls and quaysides around Wells, North Norfolk, this summer, the welfare concerns are all about the crabs.
As the schoolchildren head down to the seashore with their hooks, lines and buckets to see what they can catch, experts say they should pack a leaflet on crustacean care too.
About 10,000 leaflets will be handed out this weekend, following investigations by Cambridge University students, which revealed that overcrowding crabs in buckets could cause stress for the smaller ones and lead to fights.
