Maggots are probably the most popular baits to be used for coarse fishing in the UK.
Maggots come in a variety of colours and size, like red, white, yellow, orange, green and blue. The bait are called pinkies, which are quite small and gozzlers which are much bigger.
You can buy maggots from almost any tackle shop and are quite cheep. When you purchase maggots they are sold by either ½ pints or pints.
When hooking maggots you should nick the small flap of skin around the wide end of the maggot. Maggots can be used to catch pretty much all fish.
