Steak is becoming a popular bait for carp. It can be coloured and flavoured or dyed and will withstand the constant pecking of nuisance fish. Use raw cut into cubes straight on the hook. As with all seafood, avoid using pickled, preserved varieties as these will repel carp. Best used one at a time on the hook over a bed of loose feed.
Cockles work extremely well when fished over a bed of hemp.
Again, avoid pickled varieties. Cockles are very soft and need to be hooked through the tough foot part. This is not a good bait for fishing at distance as it will not withstand the force of casting. A good bait to fish with a waggler set-up at close range. Another seafood that I have used and caught well on.
