one of my fishy friends up that scotland place has a use for them and seems to do alright
(any animal welfare officers look away now)
he makes up his own bait 'pellets'
equipment needed: a blender
ingredients:
assortment of velvets and shore crabs, mussels, old bits of worm and bits of squid with the odd sea urchin if any turn up in the rock pools, maybe a few live prawns...
turn blender on and in they go shell and all, the shell grinds up to a paste which seems to bind the resulting mush up
the mush is then stuffed through a funnel into finger bandage and made into sausagey looking things
he uses these on a long line, 5 or six hooks, in between a couple of lobster pots, or in the gullies from the rocks. always seems to catch, esp doggies and the like from the rocks
bit gruesome though
