The standard large maggot is probably the bait most associated with everyday fishing when people think about baits. Large maggots are available at all tackle shops and eaten by all coarse fish species. Typically, anglers keep them in plastic bait tins with fine sawdust, maize meal or bran added. In the east of England, maggots are even available from vending machines at around 40 locations.
Commercial production
Maggots are the larva of the common bluebottle fly and are bred on maggot farms. They are typically fed on the carcasses of fish, chicken or turkeys, and take a week or so to grow to full size. Large maggots are naturally white in colour, but are often coloured, usually by the breeders who add dyes to the food. Hence, you can find red, yellow, orange, pink and even green versions.
History
Before the 1960s, maggots were known as gentles. Various types of maggots were described by Dame Juliana Berners in her ‘Treatise of fishing with an angle' written back in the 1420s, so have been in use as fishing bait in the UK for at least 600 years. Izaak Walton, amongst other authors of the era, describes how to breed maggots and by 1700 some fishing tackle shops were selling them commercially.
Today, there are fewer than a dozen operational maggot farms in the UK compared with around 50 back in the 1970s.
