Fishing technique in the context of "Fly fishing"

Angling (from Old English angol, meaning "hook") is a fishing technique that uses a fish hook attached to a fishing line to tether individual fish in the mouth. The fishing line is usually manipulated with a fishing rod, although rodless techniques such as handlining also exist. Modern angling rods are usually fitted with a fishing reel that functions as a cranking device for storing, retrieving and releasing out the line, although Tenkara fishing and traditional cane pole fishing are two rod-angling methods that do not use any reel. The fish hook itself can be additionally weighted with a denser tackle called a sinker, and is typically dressed with an appetizing bait (i.e. hookbait) to attract and entice the fish into swallowing the hook, but sometimes an inedible fake/imitation bait with multiple attached hooks (known as a lure) is used instead of a single hook with edible bait. Some type of bite indicator, such as a float, a bell or a quiver tip, is often used to relay underwater status of the hook to the surface and alert the angler of a fish's presence.

When angling, the fisherman (known as the angler) will first throw the hook (i.e. "cast") to a chosen area of water (i.e. fishing ground), and then patiently wait for fish to approach and devour the hookbait. It is also not uncommon for the angler to scatter some loose bait (groundbait) around the target area before even casting the hook, to better attract distant fish with scents. If a fish has succumbed to its own feeding instinct and swallowed the baited hook (i.e. "bite" or "strike"), the hook point will likely pierce into and anchor itself inside the fish jaw, gullet or gill, and the fish in turn becomes firmly tethered by 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 fishing rod back to further deepen the hook anchorage (i.e. "setting the hook") and then tries to retrieve the line back, pulling the fish closer in the process. During the line retrieval, the angler will carefully monitor the line and rod tension to avoid equipment breaking. With stronger and feistier fish, the angler might need to temporarily halt or even reverse the line retrieval to prolong the struggle time and tire out the fish (i.e. "walking" the fish), before dragging it near enough to eventually lift it out of the water (known as "landing") for a successful catch. Sometimes a hand net (or "landing net") or a long-handled hook is used to make fetching the fish easier.

Bowfishing is a fishing technique that uses specialized archery equipment to impale and retrieve fish. A bowfisher will use a bow or crossbow to shoot fish through the water surface with a barbed arrow tethered to a line, and then manually retrieve the line and arrow back, in modern times usually with a reel mounted on the bow. Unlike other popular forms of fishing where baiting and exploiting the fish's instinctual behaviors are important (e.g. angling, netting, trapping, and hand fishing such as noodling), bowfishing is similar to spearfishing and relies purely on the fisherman's own visual perception and marksmanship, and usually do not involve using other tools such as hand net.

Historically, bowfishing was practiced for subsistence, but in the 21st century it has increasingly become an outdoor sport, practiced across the United States, that is prone to unregulated waste and disposal of native species. Bowfishing has also grown in popularity due to social media influencers and YouTube outdoorsman such as the Ozark Outlaws. Sport bowfishing is unregulated and unmanaged as of 2024, but the practice is increasingly gaining attention and study across disciplines. Due to the lethality of the bow or crossbow, catch and release is not possible with bowfishing.

Destructive fishing practices are fishing practices which easily result in irreversible damage to habitats and the sustainability of the fishery ecosystems. Such damages can be caused by direct physical destruction of the underwater landform and vegetation, overfishing (especially of keystone species), indiscriminate killing/maiming of aquatic life, disruption of vital reproductive cycles, and lingering water pollution.

Many fishing techniques can be destructive if used inappropriately, but some practices (such as blasting, electrocution and poisoning) are particularly likely to result in irreversible damage to the ecosystem. These practices are mostly, though not always, illegal (see also illegal, unreported, and unregulated fishing), and even where they are illegal, regulations are often inadequately enforced.

Electrofishing is a fishing technique that uses direct current electricity flowing between a submerged cathode and anode. This affects the movements of nearby fish so that they swim toward the anode, where they can be caught or stunned.

Electrofishing is a common scientific survey method used to sample fish populations to determine abundance, population density and species composition. When performed correctly, electrofishing results in no permanent harm to the fish, which return to their natural mobility state in as little as two minutes after being caught.

Cormorant fishing is a traditional fishing technique in which fishermen use trained cormorants to catch fish in rivers. Historically, cormorant fishing has taken place in China and Japan, as well as Greece, North Macedonia, and briefly, England and France. Sometimes known as "duck fishing," it was attested as a method used by the ancient Japanese in the Book of Sui, the official history of the Sui dynasty of China, completed in 636 CE. Though cormorant fishing was once a successful enterprise, its primary use today is for the tourism industry. This artisan fishing method is no longer used anywhere except southwestern China, where it is also under threat from competition from more modern methods.

To control the birds, the fishermen tie a loose snare near the base of the bird's throat. The snare does not stop the bird from swallowing small fish, but prevents the bird from swallowing larger fish, which are held temporarily in their gullet. When a cormorant has caught a fish in its throat, the fisherman brings the bird back to the boat and has it regurgitate the fish.

Handline fishing, or handlining, is a fishing technique where a single fishing line is held in the hands, rather than with a fishing rod like the usual angling, of which handlining is a subtype. Handlining is not to be confused with handfishing, which is catching fish by hand. When handlining, one or more fishing lures or baited hooks are attached to the line, and a fishing lure and often a weight and/or a fishing float can also be attached to the line. Handlining is among the oldest forms of fishing and is still practiced throughout the world today.

The fishing bait can be still fished, trolled or jigged up and down in a series of short movements. Often handling is done close to the bottom of the body of water but can also be done near or on the surface.

Snagging, also known as snag fishing, snatching, snatch fishing, jagging (Australia and New Zealand), or foul hooking, is a fishing technique for catching fish that uses sharp grappling hooks tethered to a fishing line to externally impale (i.e. "snag") into the flesh of the fish, without needing the fish to swallow any hook with its mouth like in angling. This is achieved by suddenly and vigorously pulling the line (either by handlining or with a rod) when movement is felt, causing the snag hook to "claw" into and grapple any nearby fish like a gaff. Weighted multi-hook rigs can be used to increase chances of success, and modern technologies such as underwater video camera can also be used to visually aid and time the snagging.

Some herbivorous/algaevorous fish species, such as paddlefish, are not attracted to normal angling baits or lures as they primarily filter-feed on plankton. While these fish can be caught using nets, spears or pole hooks, snagging is also used as a less strenuous and more versatile technique. There are also some species of salmon that can be legally harvested by snagging, and are targeted as they migrate upstream to spawn, making them easier to target, and at a time when the fish are at the end of their life cycle.
