Bottom fishing in the context of Fishing float

Groundbait is a fishing bait that is either thrown or "balled" into the water as an "appetizer" in order to olfactorily attract more fish to a designated area (i.e. fishing ground) for more efficient catching via angling, netting, trapping, or even spearing and shooting. Groundbaits are typically scattered separately from the hook and usually before even casting any rod or net, although in bottom fishing they can be deployed synchronously with hookbaits while contained inside a gradual-release device also attached to the fishing line known as a method feeder.

Groundbaits are often used in freshwater coarse fishing (where the target fish are commonly omnivorous or algivorous and might not be easily drawn to the hookbait), and can be custom-made personally by the angler or bulk-purchased from dedicated manufacturers. There are many different recipes of groundbaits that can be used to target specific species of fish. Groundbait can differ by the sizes of the crumbs, type of seed, colour and smell. The angler can also mix additives to the groundbait to alter its firmness in order to control the rate of bait release or breakdown once in the water.

A quiver tip is a flexible extension to a fishing rod which is designed to vibrate, or quiver, when a fish takes the bait. The main characteristic of its design is its sensitivity. It is a popular and very effective method of bite indication both on still and running water, and is used far more often in bottom fishing. It is not used in game fishing (i.e. for salmon, trout and sea trout) and is seldom, if ever, used when fishing for very large coarse fish (e.g. carp or pike). In essence, the angler watches the tip of the fishing rod to detect bites as opposed to, say, a float or an electronic bite alarm.
