Groundbait is fishing bait that is either cast or 'balled' into the water in order to attract fish to the fishing area. It is often used in coarse fishing. Ground-bait can be made by the angler or pre-bought by ground-bait manufactures. There are many different types of ground-bait that can be used to target specific species of fish. Ground-bait can differ by the sizes of the crumbs, type of seed, colour and smell. The angler can also mix additives to the ground-bait to alter its firmness in order to control the release or breakdown of the bait once in the water.
