Spearfishing in the context of "Hand fishing"

Fishing is the activity of trying to catch fish. Fish are often caught as wildlife from the natural environment (freshwater or marine), but may also be caught from stocked bodies of water such as ponds, canals, park wetlands and reservoirs. Fishing techniques include trawling, longlining, jigging, hand-gathering, spearing, netting, angling, shooting and trapping, as well as more destructive and often illegal techniques such as electrocution, blasting and poisoning.

The term fishing is also used more broadly to include catching aquatic animals other than fish, such as crustaceans (shrimp/lobsters/crabs), shellfish, cephalopods (octopus/squid) and echinoderms (starfish/sea urchins). The term is not normally applied to harvesting fish raised in controlled cultivations (fish farming). Nor is it normally applied to hunting aquatic mammals, where terms like whaling and sealing are used instead.

Fishing techniques are methods for catching fish. The term may also be applied to catching other aquatic animals such as molluscs (shellfish, squid, octopus) and edible marine invertebrates.

Fishing techniques include hand-gathering, spearfishing, netting, angling and trapping. Recreational, commercial and artisanal fishers use different techniques, and also, sometimes, the same techniques. Recreational fishers fish for pleasure or sport, while commercial fishers fish for profit. Artisanal fishers use traditional, low-tech methods, for survival in developing countries, and as a cultural heritage in other countries. Mostly, recreational fishers use angling methods and commercial fishers use netting methods.

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.

Fishing tackle is the equipment used by anglers when fishing. Almost any equipment or gear used in fishing can be called fishing tackle, examples being hooks, lines, baits/lures, rods, reels, floats, sinkers/feeders, nets, spears, gaffs and traps, as well as wires, snaps, beads, spoons, blades, spinners, clevises and tools that make it easy to tie knots.

Tackle attached to the end of a fishing line that gets cast out along with the bait are referred to as terminal tackle. Terminal tackle can include hooks, leaders, floats, sinkers/feeders, swivels and attached snaps and/or split rings. Sometimes the term "rig" is used for a specific assemblage of terminal tackle.

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.

Freediving, free-diving, free diving, breath-hold diving, or skin diving, is a mode of underwater diving that relies on breath-holding (apnea) until resurfacing rather than the use of breathing apparatus such as scuba gear.Besides the limits of breath-hold, immersion in water and exposure to high ambient pressure also have physiological effects that limit the depths and duration possible in freediving.

Examples of freediving activities are traditional fishing techniques, competitive and non-competitive freediving, competitive and non-competitive spearfishing and freediving photography, synchronised swimming, underwater football, underwater rugby, underwater hockey, underwater target shooting and snorkeling. There are also a range of competitive apnea disciplines; in which competitors attempt to attain great depths, times, or distances on a single breath.
