Anglers use maggots usually provided by commercial suppliers to catch non-predatory fish.

Maggots are the most popular bait for anglers in Europe. Anglers throw handfuls into the "swim" they are targeting, attracting the fish to the area. The angler will then use the largest or "perceived" most attractive maggots on the hook, hoping to be irresistible to the fish.

Commercial maggot breeders from the UK sell their maggots to tackle dealers throughout the E.U. and North America.

In North America, maggots ("spikes" or "eurolarvae" as they have come to been known) have been used for years mainly as ice fishing bait; however, recently anglers have started using them year round.
