Angling is a fishing technique that uses a fish hook or "angle" (from Old English angol) attached to a fishing line to tether individual fish in the mouth. The fishing line is usually manipulated via a fishing rod, although rodless techniques such as handlining and longlining also exist. Modern angling rods are usually fitted with a reel that functions as a cranking device for storing, retrieving and releasing out the line, although Tenkara fishing and cane pole fishing are two rod-angling methods that do not use any reel. The hook itself can be additionally weighted with a dense tackle called a sinker, and is typically dressed with an appetizing bait to attract the fish and enticing it into swallowing the hook, but sometimes an inedible fake bait with multiple attached hooks (known as a lure) is used instead of a single hook with edible bait. A bite indicator, such as a float or a quiver tip, is often used to relay underwater status of the hook to the surface. When angling, the fisherman (known as the angler) will first throw the hook (i.e. "cast") to a chosen area of water, and then patiently wait for fish to attack and eat the hookbait. It is also not uncommon for the angler to scatter some loose bait (groundbait) around the spot before even casting the hook, in order to better attract fish with scents. If a fish has succumbed to its own feeding instinct and swallowed the hook (i.e. "bite" or "strike"), the hook point will pierce into and anchor itself inside the fish mouth, gullet or gill, and the fish in turn becomes firmly tethered to the fishing rod via the fishing line. Once the fish is hooked (often colloquially called "fish-on"), any struggles and attempts to escape will pull along the line, causing the bite indicator to signal the angler, who jerks the rod to further secure the hook anchorage (i.e. "setting the hook") and then tries to retrieve the line back, pulling the fish closer in the process.
