Trained animals Chinese man with fishing cormorant.In China and Japan, the practice of cormorant fishing is thought to date back some 1300 years. Fishermen use the natural fish-hunting instincts of the cormorants to catch fish, but a metal ring placed round the bird's neck prevents large, valuable fish being swallowed. The fish are instead collected by the fisherman.[19] The people of Nauru used trained frigatebirds to fish on reefs. The practice of tethering a remora, a sucking fish, to a fishing line and using the remora to capture sea turtles probably originated in the Indian Ocean. The earliest surviving records of the practice are Peter Martyr d'Anghera's 1511 accounts of the second voyage of Columbus to the New World (1494).[20] However, these accounts are probably apocryphal, and based on earlier, no longer extant accounts from the Indian Ocean region. Dating from the 1500s in Portugal, Portuguese Water Dogs were used by fishermen to send messages between boats, to retrieve fish and articles from the water, and to guard the fishing boats. Labrador Retrievers have been used by fishermen to assist in bringing nets to shore; the dog would grab the floating corks on the ends of the nets and pull them to shore. [edit] Toxins Main article: Cyanide fishing Many hunter gatherer cultures use poisonous plants to stun fish so that they become easy to collect by hand. Some of these poisons paralyse the fish, others are thought to work by removing oxygen from the water.[21] Cyanides are used to capture live fish near coral reefs for the aquarium and seafood market. This illegal fishing occurs mainly in or near the Philippines, Indonesia, and the Caribbean to supply the 2 million marine aquarium owners in the world. Many fish caught in this fashion die either immediately or in shipping. Those that survive often die from shock or from massive digestive damage. The high concentrations of cyanide on reefs harvested in this fashion damages the coral polyps and has also resulted in cases of cyanide poisoning among local fishermen and their families. [edit] Explosives Main article: Blast fishing Dynamite or blast fishing, is done easily and cheaply with dynamite or homemade bombs made from locally available materials. Fish are killed by the shock from the blast and are then skimmed from the surface or collected from the bottom. The explosions indiscriminately kill large numbers of fish and other marine organisms in the vicinity and can damage or destroy the physical environment. Explosions are particularly harmful to coral reefs.[22] Blast fishing is also illegal in many waterways around the world. [edit] Electrofishing A relatively new fishing technique is electrofishing, typically used for stream classification surveys and catching brood stock for hatcheries, or making estimates of populations in a body of water. A gated pulse of direct current is used to cause muscular contractions in a fish, called galvanotaxis, causing them to turn towards the source of the electrical current and swim towards it when correct pulse speeds and durations are used, along with correct current. A low voltage or short pulse with long gaps will cause the fish to swim away from the device, and high voltage or long pulses with short rests can cause galvanonarcosis, or unconsciousness. Techniques for setting pulse length and patterns, current and voltage require great skill to fish effectively without killing or injuring fish if they are to be left unharmed. Dissolved minerals in the water can decrease resistance causing less of the current to pass through the fish, whereas fish recently entering fresh water from the ocean have high salinity and are more prone to electric shock. Also the smaller the fish, and consequently the less surface area in contact with the water, the higher the current required to produce galvanotaxis. Smaller fish also require shorter pulses, closer together, while large fish should have longer pulses at lower power and longer gaps between pulses. Rigs can be battery powered back-packs or powered by a generator if they are mounted in a boat. They are typically equipped with a "dead-man switch" and a tilt switch to disable the device if the unit is tipped or the operator incapacitated. Protective equipment must be worn to isolate the operator and prevent electrocution. Electro-fishing is also used to illegally catch Razorfish or Spoots, using a boat based generator. Current is passed into the sediment causing the Razorfish to 'jump' and be harvested by divers. For obvious reasons this method of electro-fishing is banned due to the risk to the divers. [edit] Modern fishing [edit] Recreational fishing Angling.Main article: Angling. Recreational fishing and the closely related (nearly synonymous) sport fishing describe fishing for pleasure or competition. Recreational fishing has conventions, rules, licensing restrictions and laws that limit the way in which fish may be caught, The International Game Fishing Association (IGFA) makes and oversees these obligations. Typically, these prohibit the use of nets and the catching of fish with hooks not in the mouth. The most common form of recreational fishing is done with a rod, line and hooks attached to any of a wide range of lures or baits. Most types of fishing tackle are made in a professional manufacturing facility and other for hobbyist enjoy making their own baits, examples would include the use of Fishing worm molds, etc. This practice is known as angling. One method of growing popularity is kayak fishing. Kayak fisherman fish from sea kayaks in an attempt to level the playing field with fish and to further challenge their abilities. Kayaks are extremely stealthy and can allow anglers to reach areas unfishable from land or by conventional boat. In angling, it is sometimes expected or required that fish all be returned to the water (catch and release). The practice, however, is viewed by some with disapproval as they consider it unethical to inflict pain on a fish for fun or sport and not for reasons of capturing food. Anglers deny this charge, pointing out that fish commonly feed on hard and spiky prey items, and as such can be expected to have tough mouths, and also that some fish will re-take a lure they have just been hooked on, a behavior that is unlikely if being hooked were painful. There is also some research that shows certain types of fish such as catfish, do not have nerves around their mouth. They most likely do not have nerves in their mouths due to the fact that they eat animals such as crawfish that can pinch. In a real sense, the suitability of catch and release is an ethical consideration and, as such, a science-based conclusion on the issue is unavailable. Scientific studies show a wide range of survival, depending on species, environmental conditions, fish density and research design (methodology). The difficulty of doing such experiments is closely linked to the fact that negative effects of being exposed to fishing gears develop over a long time. Keeping fish trapped over a long period of time creates a lot of noise which makes it hard to single out the effect of the catch from the effect of the chosen methodology. Nevertheless, several studies have now returned very high survival rates (95%+) for species caught on fly and lures, which generally tend to hook fish in the mouth and thus aid catch and release fishing. Proponents of catch and release also contend that the practice is increasingly necessary in order to conserve fish stocks in the face of burgeoning human populations, mounting fishing pressure and worsening habitat degradation. Opponents would prefer to ban or to severely restricting angling, a suggestion most anglers find unpalatable. Recreational fishermen can have profound deleterious effects on fish stocks in commercial lakes, this is due to anglers with poor knowledge of how to protect the fish from damage or stress once out of the water. The fish which suffer most are those of large, slow growing species such as carp. The only way for growing numbers of recreational fishermen to continue fishing is to reduce their impact on fish populations. Catch and release, in combination with techniques such as strong tackle (to get fish in quickly, for release in good condition), careful handling of fish and barbless hooks (to reduce physical damage) and quick release lead systems such as the Korda quick release system or the E.S.P. variety may be useful tools in this endeavour. Barbless hooks reduce damage to minimal levels, reduce de-hooking time and greatly aid in catch and release. Many keen catch and release anglers use barbless hooks. Barbless hooks can be purchased, or created by crushing the barbs on a normal hook flat with a pair of needle-nosed pliers. It is popularly believed barbless hooks lead to more lost fish, but ensuring lures are equipped with split rings and keeping the line tight while fighting fish will reduce fish losses to levels similar to those of barbed hooks. Also using circle hooks will cause the least amount of damage to a fish. The design of the hook is very simple, it is like a circle. When a fish bites the bait the hook's design causes it to hook in the side of the fish's mouth every time. This makes it very easy to remove the hook with minimal damage. Setting your hook when a fish bites is also different. Instead of snatching your line you slowly set your hook. This alone is a lot less stressful on the fish. A circle hook is the best choice for catch and release programs. A recent phenomenon of recreational fishing are fishing competitions (tournaments) where fishermen compete for prizes based on the total weight of a given species of fish caught within a predetermined time. This sport evolved from local fishing contests into large competitive circuits, especially in North America. Competitors are most often professional fishermen who are supported by commercial endorsements. Other competitions is purely on length with mandatory catch and release, either longest fish or total length is documented with camera and a mandatory sticker, is more fair since it’s hard to weigh a living fish accurately in a boat. Big-game fishing describes fishing from boats to catch large open-water species such as tuna, sharks and marlin. Noodling and Trout tickling may be pursued as a recreation. Laws made to control recreational fishing frequently also attempt to control
the harvest of other aquatic species, such as frogs and turtles. Clyde's Key West Fishing |
