Catch and release is a practice within recreational fishing where after capture, often a fast measurement and weighing of the fish is performed, followed by posed photography as proof of the catch, and then the fish are unhooked and returned live to the water. Using barbless hooks, it is often possible to release the fish without removing it from the water (a slack line is frequently sufficient).

Catch and release is a conservation practice developed to prevent overharvest of fish stocks in the face of growing human populations, mounting ecological pressure, increasingly effective fishing tackle and techniques, inadequate fishing regulations and enforcement, and habitat degradation. Sports fishers have been practicing catch and release for decades, including with some highly pressured fish species.

History

In the United Kingdom, catch and release has been performed for more than a century by coarse fishermen in order to prevent target species from disappearing in heavily fished waters. Since the latter part of the 20th century, many salmon and sea trout rivers have been converted to complete or partial catch and release. In Scotland, the River Dee operates a full catch and release policy for salmon, grilse and sea trout. [1]

In the United States, catch and release was first introduced as a management tool in the state of Michigan in 1952 as an effort to reduce the cost of stocking hatchery-raised trout. Anglers fishing for fun rather than for food accepted the idea of releasing the fish while fishing in "no-kill" zones. Conservationists have advocated catch and release as a way to ensure sustainability and to avoid overfishing of fish stocks. Lee Wulff, a New York-based fly angler, author and film maker, promoted catch and release as early as 1936 with the phrase "Game fish are too valuable to be caught only once." [2] Don Martinez a West Yellowstone, Montana, fly shop owner, promoted catch and release in his 1930–40s newsletters sent to Eastern anglers. [3]

In Australia, catch and release caught on slowly, with some pioneers practicing it in the 1960s, and the practice slowly became more widespread in the 1970s and 1980s. Catch and release is now widely used to conserve—and indeed is critical in conserving—vulnerable fish species like the large, long lived native freshwater Murray Cod and the prized, slowly growing, heavily fished Australian bass, heavily fished coastal species like Dusky Flathead and prized gamefish like striped marlin.[ citation needed ]

In Ireland, catch and release has been used as a conservation tool for Atlantic salmon and sea trout fisheries since 2003. A number of fisheries now have mandatory catch and release regulations. [4] Catch and release for coarse fish has been used by sport anglers for as long as these species have been fished for on this island. However catch and release for Atlantic salmon has required a huge turn about in how many anglers viewed the salmon angling resource. To encourage anglers to practice catch and release in all fisheries a number of government led incentives have been implemented. [5]

In Canada, catch and release is mandatory for some species. Canada also requires in some cases the use of barbless hooks to facilitate release and minimize injury.[ citation needed ]

In Switzerland and Germany, catch and release fishing is considered inhumane and is now banned. [6] In Germany, the Animal Welfare Act states that "no-one may cause an animal pain, suffering or harm without good reason". [7] This leaves no legal basis for catch and release due to its argued inherent lack of "good reason", and thus personal fishing is solely allowed for immediate food consumption. Additionally, it is against the law to release fish back into the water if they are above minimum size requirements and are not a protected species or in closed season.

In 2011, the National Park Service in Yellowstone National Park began reversing decades of regulation that promoted catch and release and other techniques that protected fish populations. In the name of native fish conservation, they began mandatory kill regulations on rainbow and brook trout in the Lamar River drainage and encouraged unlimited taking and disposal of non-native species, including brown trout in some park waters. [8] [9]

Into the 21st century, there has been an emphasis on the development and refinement of science-based practices to increase the likelihood that released fish will survive (e.g., see research by Steven J. Cooke). That work led to the development of the UN FAO Technical Guidelines for Recreational Fisheries. [10]

Effective catch and release fishing techniques avoid excessive fish fighting and handling times by using sufficiently strong tackle and barbless hooks, avoid damage to fish skin, scale and slime layers from nets, dry hands and dry, hot or rough surfaces (that leave fish vulnerable to oomycete skin infections), and avoid damage to jaw ligaments and vertebrae by suspending fish from jaws or gills for weighing or handling. If a net must be used it is important that it is pre-wetted and is not abrasive to the fish (such as a rubber coated net or very dense lightweight mesh), because fish can easily damage themselves in a normal net while thrashing.[ citation needed ] The use of barbless hooks is an important aspect of catch and release; barbless hooks reduce injury and handling time, increasing survival. Frequently, fish caught on barbless hooks can be released without being removed from the water, and the hook(s) effortlessly slipped out with a single flick of the pliers or leader. Barbless hooks can be purchased from several major manufacturers or can be created from a standard hook by crushing the barb(s) flat with needle-nosed pliers. Some anglers avoid barbless hooks because of the belief that too many fish will escape. Concentrating on keeping the line tight at all times while fighting fish, equipping lures that do not have them with split rings, and using recurved point or "Triple Grip" style hooks on lures, will keep catch rates with barbless hooks as high as those achieved with barbed hooks.[ citation needed ]

One study looking at brook trout found that barbless hooks had no statistically significant effect on mortality rates when fish were hooked in the mouth, but observed that they did reduce mortalities compared to barbed hooks if fish were hooked deeper. [11] The study also suggested bait fishing does not have a significantly higher mortality when utilized in an active style, rather than a passive manner that allows the fish to swallow the bait. [11]

The effects of catch and release vary from species to species. A study of fish caught in shallow water on the Great Barrier Reef showed high survival rates (97%+), [12] for released fish if handled correctly and particularly if caught on artificial baits such as lures. Fish caught on lures are usually hooked cleanly in the mouth, minimizing injury and aiding release. Other studies have shown somewhat lower survival rates for fish gut-hooked on bait if the line is cut and the fish is released without trying to remove the hook.[ citation needed ]

Debate over pain in released fish

Opponents of catch and release argue that fish are highly evolved vertebrates that share many of the same neurological structures that in humans are associated with pain perception. They cite studies showing that, neurologically, fish are quite similar to higher vertebrates and that blood chemistry reveals that hormones and blood metabolites associated with stress are quite high in fish struggling against hook and line. The idea that fish do not feel pain in their mouths has been studied at the University of Edinburgh and the Roslin Institute by injecting bee venom and acetic acid into the lips of rainbow trout; the fish responded by rubbing their lips along the sides and floors of their tanks in an effort to relieve themselves of the sensation. [13]

Lead researcher Lynne Sneddon wrote, "Our research demonstrates nociception and suggests that noxious stimulation in the rainbow trout has adverse behavioral and physiological effects. This fulfills the criteria for animal pain." A 2014 paper provides a critique of existing studies that purport to demonstrate that fish feel pain. [14] James D. Rose of the University of Wyoming argues this may demonstrate a chemical sensitivity rather than pain and that the evidence for pain sensation in fish is ambiguous. [15] [16]

Injury and mortality in released fish

A metastudy in 2005 found that the average catch and release mortality rate was 18%, but varied greatly by species. [17] During an Oklahoma Department of Wildlife Conservation study, up to 43 percent of fish released after being caught died within six days as a result of inadequate holding and weigh in procedures during tournaments. [18] More recent studies reported in Montana estimate that approximately 20% of released trout die from injuries or stress and for those that do not die, their injuries may significantly reduce their ability to feed and grow. [19]

Emerging research suggests catch and release does not work very well with fish caught when deep sea fishing. Most deep sea fish species suffer from the sudden pressure change when wound to the surface from great depths; these species cannot adjust their body's physiology quickly enough to follow the pressure change. The result is called "barotrauma". Fish with barotrauma will have their enormously swollen swim-bladder protruding from their mouth, bulging eyeballs, and often sustain other, more subtle but still very serious injuries. Upon release, fish with barotrauma will be unable to swim or dive due to the swollen swim-bladder. The common practice has been to deflate the swim bladder by pricking it with a thin sharp object before attempting to release the fish. Emerging research also indicates both barotrauma and the practice of deflating the swimbladder are both highly damaging to fish, and that survival rates of caught-and-released deep-sea fish are extremely low. [20] Barotrauma requires that fish be caught at least 10–15 m (30–50 ft) below the surface. Many surface caught fish, such as billfish, and all fish caught from shore do not meet this criterion and thus do not suffer barotrauma.[ citation needed ]

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

Trolling is a method of fishing where one or more fishing lines, baited with lures or bait fish, are drawn through the water at a consistent, low speed. This may be behind a moving boat, or by slowly winding the line in when fishing from a static position, or even sweeping the line from side-to-side, e.g. when fishing from a jetty. Trolling is used to catch pelagic fish such as salmon, mackerel and kingfish.

<span class="mw-page-title-main">Fly fishing</span> Angling technique

Fly fishing is an angling technique that uses an ultra-lightweight lure called an artificial fly, which typically mimics small invertebrates such as flying and aquatic insects to attract and catch fish. Because the mass of the fly lure is insufficient to overcome air resistance, it cannot be launched far using conventional gears and techniques, so specialized tackles are used instead and the casting techniques are significantly different from other forms of angling. It is also very common for the angler to wear waders, carry a hand net, and stand in the water when fishing.

<span class="mw-page-title-main">Angling</span> Fishing technique

Angling 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 via 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 to attract and entice the fish into swallowing the hook, but sometimes an inedible fake/imitation bait with multiple attached hooks 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.

<span class="mw-page-title-main">Longline fishing</span> Commercial fishing technique

Longline fishing, or longlining, is a commercial fishing angling technique that uses a long main line with baited hooks attached at intervals via short branch lines called snoods or gangions. A snood is attached to the main line using a clip or swivel, with the hook at the other end. Longlines are classified mainly by where they are placed in the water column. This can be at the surface or at the bottom. Lines can also be set by means of an anchor, or left to drift. Hundreds or even thousands of baited hooks can hang from a single line. This can lead to many deaths of different marine species. Longliners – fishing vessels rigged for longlining – commonly target swordfish, tuna, halibut, sablefish and many other species.

Coarse fishing is a phrase commonly used in Great Britain and Ireland. It refers to the angling for rough fish, which are fish species considered undesirable as food or game fish. Freshwater game fish are all salmonids, particularly salmon, trout and char. Generally, coarse fish are freshwater fish that are not salmonids, though there is often disagreement over whether grayling should be classified as a game fish or a coarse fish.

<span class="mw-page-title-main">Environmental impact of fishing</span>

The environmental impact of fishing includes issues such as the availability of fish, overfishing, fisheries, and fisheries management; as well as the impact of industrial fishing on other elements of the environment, such as bycatch. These issues are part of marine conservation, and are addressed in fisheries science programs. According to a 2019 FAO report, global production of fish, crustaceans, molluscs and other aquatic animals has continued to grow and reached 172.6 million tonnes in 2017, with an increase of 4.1 percent compared with 2016. There is a growing gap between the supply of fish and demand, due in part to world population growth.

<span class="mw-page-title-main">Fishing bait</span> Object or substance used to attract fish

Fishing bait is any luring substance used specifically to attract and catch fish, typically when angling with a hook and line. There are generally two types of baits used in angling: hookbaits, which are directly mounted onto fish hooks and are what the term "fishing bait" typically refers to; and groundbaits, which are scattered separately into the water as an "appetizer" to attract the fish nearer to the hook. Despite the bait's sole importance is to provoke a feeding response out of the target fish, the way how fish react to different baits is quite poorly understood.
