Fishing bait is any substance used to attract and catch fish, e.g. on the end of a fishing hook, or inside a fish trap. Traditionally, nightcrawlers, insects, and smaller bait fish have been used for this purpose. Fishermen have also begun using plastic bait and, more recently, electronic lures, to attract fish.
Studies show that natural baits like croaker and shrimp are more recognized by the fish and are more readily accepted. Which of the various techniques a fisher may choose is dictated mainly by the target species and by its habitat. Bait can be separated into two main categories: artificial baits and natural baits.
Using lures is a popular method for catching predatory fish. Lures are artificial baits designed to resemble the appearance and/or the movement of prey, usually small fish. The lure may require a specialised presentation to impart an enticing action as, for example, in fly fishing. A common way to fish a soft plastic worm is the Texas Rig.
The natural bait angler, with few exceptions, will use a common prey species of the fish as an attractant. The natural bait used may be alive or dead. Common natural baits include worms, leeches (notably bait-leech Nephelopsis obscura), minnows, frogs, salamanders, and insects. Natural baits are effective due to the lifelike texture, odour and colour of the bait presented. Cheese has been known to be a very successful bait due to its strong smell and light colours.
The common earthworm is a universal bait for fresh water angling. Grubs and maggots are also excellent bait when trout fishing. Grasshoppers, bees and even ants are also used as bait for trout in their season, although many anglers believe that trout or salmon and many other fresh water fish roe is superior to any other bait. In lakes in southern climates such as Florida, USA, fish such as bream will take bread bait. Bread bait is a small amount of bread, often moistened by saliva, balled up to a small size that is bite size to small fish.
