Casting (fishing)
In angling, casting is the act of the angler throwing the bait and hook (or a lure) as well as other attached terminal tackles out over the water, typically by slinging a fishing line manipulated by a long, elastic fishing rod. The term itself may also be used for setting out a net when artisanal fishing.
The basic technique is to quickly flick/swing the rod forward towards the water, with the inertia of the tackles lagging and bending the rod backward (i.e. "loading" the rod), and then use the "springing" (elastic rebound) of the rod to "hurl" and rapidly sling the line forward, which in turn will launch out the hook and bait.[1]
There are several methods anglers can use to attempt to cast farther,[2] the most prominent of which is the shifting of body weight towards the front foot in kinematic synchrony to the forward swinging of the rod. That, combined with using a longer rod, stopping the rod swing at 45 degrees, and using correctly weighted and more aerodynamic terminal tackles, will help anglers cast farther. There are also variation techniques the anglers can use to cast the tackles more accurately to an exact location on the water or to get past potential obstacles.
Casting techniques[edit]
Casting techniques vary with the type and style of angling involved. Different casting techniques are also used by different anglers according to personal preferences and proficiency, and each technique is named uniquely. In the single-hand sidearm cast, the angler first points the rod towards the targeted area, and then swing it back and then quickly forward like a tennis stroke, creating a cast with a relatively flat trajectory. Drop-casting, on the other hand, is all about fast sinking, and the angler must bring the rod high before releasing the finger grip on the line and drop the cast into water with full force. The double-handed overhead cast, used more for distance, uses a kendo-like overhead swing to throw the line as far as possible.[3]
Freshwater anglers typically use lightweight, faster-action rods and for panfishing or finesse fishing for popular mid-sized game fishes such as black bass or trout, while sturdier, heavier rods are used for larger, stronger and feistier fish. When casting light rods, sidearm casting techniques are typically used. If more distance is needed, an overhead cast is more common. For smaller, weed-rich bodies of water (such as ponds, small rivers/creeks and wetlands), where casting accuracy is more important than distance, anglers sometimes use a swinging technique known as flipping or pitching, an elastic technique known as a slingshot cast, or a softball pitch-like technique that can make the bait/lure skim the water known as a roll cast.
Saltwater anglers usually use heavier rods and lines, as they often use baits and lures that are bigger and heavier than those used on freshwater. Heavier again are the rods and lines used in surfcasting, and specialized two-handed casting techniques are used to provide the added distances required for the baits/lures to get past the surfs and reach inshore fish feeding near the upwellings. In these casts, the angler utilizes the entire body, rather than just the arms, to deliver the momentum of the cast, which may travel many hundreds of meters/feet.
Fly fishermen use ultralight artificial flies as a lure and thus use flexible lightweight rods to cast heavy lines. The technique often involve swinging the line in circles multiple times to build up momentum, before releasing the hand hold on the line and pointing the rod towards the intended direction, so the line ends up creating a loop that propagates like a wave and carries the fly out towards the far end with great accuracy. Once on or in the water, the fly can then mimic aquatic insects or other invertebrates and attract insectivorous fish such as trout and anadromous salmon.
