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.
