A trotline is a heavy fishing line with shorter, baited branch lines commonly referred to as snoods suspending down at intervals using clips or swivels, with a hook at the free end of each snood.
Trotlines are used in commercial angling and can be set up across a channel, river, or stream to cover an entire span of water. There are many ways to set a trotline, with most methods involving weights at the end of snoods to keep them neatly below the water surface. They are used for catching crabs [1] or fish (particularly catfish [2] ). Trotlines should be used with caution as they are deemed illegal in many locations.
Trotlines are similar to a longline, but longlines are fixed to a surface vessel at only one end and usually towed along the water, while trotlines are fixed (usually stationarily) to the surface at both ends via anchored boats, buoys or structures. It is also contrasted with droplines, as a trotline's mainline is laid horizontally across water with a series of vertically suspended snood lines, while a dropline's mainline is suspended vertically (using a weight) from a floating bouy with a series of side-branching snoods.
In its use in the commercial crabbing industry (on the Chesapeake Bay for example), a trotline is used as a variation of a setline. Webster's dictionary defines a setline as being "a long heavy fishing line to which several hooks are attached in series." A trotline is defined as "a comparatively short setline used near shore or along streams." Some other common variations of a setline include limblines, throwlines, and juglines. The Virginia Department of Game & Fisheries defines a trotline as "a line without a rod or reel attached that need not be held in the hand or closely attended."
As used for crabbing, a trotline is nothing more than a long line, resting on the bottom and anchored at both ends, to which a series of baits are attached at intervals of two to six feet. The baits are attached to the main line by simple slipknots or by shorter lines called dropper lines (known as trots or snoods.) Crab trotlines are usually baited with chicken necks, chicken livers, bull lips, eels or other inexpensive baits. Maryland blue crabs are harvested by waterman on small workboats using trotlines and crab pots. When caught by trotlines, the line is set and the workboat moves slowly end to end, bringing the line to the surface where the waterman catches the crab. Crabs on a trotline are not hooked, they are simply netted by the waterman at the surface, with the workboat moving slowly enough through the water that the crab does not discern movement as it eats the bait. The crab having been netted at the surface, the trotline moves back to or toward the bottom with the same bait intact to attract another crab.
Depending on the length of the trotline (usually from at least 100 yards and up to a mile), a commercial waterman can catch anywhere from 4 bushels to 20 bushels of crabs daily.
Constructing a trotline is quite simple. Basic supplies needed are fishing hooks, clamps, swivels, fishing line, and a durable cord or lightweight rope used for the main line. Before constructing the trotline, it is a good idea to measure the span of the body of water being fished in order to give the main line an appropriate length. Once this is done, drop lines are set along the main line by threading clamps on the line with swivels between them. Fishing line is attached to the swivels and hooks are tied to the end of the fishing line.
Typically, the drop lines are set so that the hook of one line can not touch the hook of another line, to prevent the fish from getting tangled up in multiple lines, or getting tangled in lines with other fish already on the line. This might mean using lines just over 1 foot long and having the lines spaced in 3 foot intervals. It is also typical to avoid setting lines directly over stumps, branches or other obstacles that might cause the fish to get tangled. This is done so that any released fish has a better chance of being in good health.
Weighting the line is a matter of personal preference. In areas along rivers and channels with strong currents, large weights may be added to keep the line from being pulled close to the surface as the water passes over the line. Most weights used on trotlines are homemade as typical weights used by anglers do not weigh enough to keep the line in place. These may be made out of cement, cinder blocks, or even small boat anchors. Other common weights used include old fashioned window weights, chisel plowshares and other similar sized scrap metal.
It is important to make sure that the area where the line is to be set is free of swimmers, boaters, or other people on or near the water as it is difficult to detect where a trotline is while it is underwater. It is easy to get tangled in the line and for hooks to become embedded in a person's skin, making the need for proper marking of the line crucial. A float on each side of a section of channel is a good indication that a trotline has been set.
Setting the line consists of anchoring one end to one side of the channel, then taking the line out to the other side, baiting the hooks while this is being done. Trees or rocks make good anchor points for trotlines, but attention should be given that the line is not tied around rough or sharp edges that might cut through the line.
Once the line is set, the angler need only check the line periodically throughout the day to see if any fish have been caught. While checking the line, one can also replace bait, untangle drop lines, and retrieve any fish on the line. Care is needed when checking or setting the line to make sure that no one is accidentally hooked in any part of the process.
Be sure to check local and state regulations as trotlines are not legal for use in all areas. Additionally, many localities that allow trotlines do not allow the use of live bait fish, particularly in areas with populations of largemouth bass or similar predator fish, as they can be severely injured or killed when attempting to escape. This is why cut bait is the most commonly used bait for attracting catfish.
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.
A fishing line is any flexible, high-tensile cord used in angling to tether and pull in fish, in conjunction with at least one hook. Fishing lines are usually pulled by and stored in a reel, but can also be retrieved by hand, with a fixed attachment to the end of a rod, or via a motorized trolling outrigger.
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.
Ice fishing is the practice of catching fish with lines and fish hooks or spears through an opening in the ice on a frozen body of water. Ice fishers may fish in the open or in heated enclosures, some with bunks and amenities.
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.
A fishing lure is any one of a broad category of artificial angling baits that are inedible replicas designed to mimic prey animals that attract the attention of predatory fish, typically via appearances, flashy colors, bright reflections, movements, vibrations and/or loud noises which appeal to the fish's predation instinct and entice it into gulping the lure. Angling activities using lures are known as lure fishing.
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.
Hippoglossus stenolepis, the Pacific halibut, is a species of righteye flounder. This very large species of flatfish is native to the North Pacific and is fished by commercial fisheries, sport fishers, and subsistence fishers.
A spinnerbait or spinner is any one of a family of hybrid fishing lures that combines the designs of a swimbait with one or more spoon lure blades. Spinnerbaits get the name from the action of the metallic blades, which passively revolve around the attachment point like a spinning propeller when the lure is in motion, creating varying degrees of vibration and flashing that mimic small fish or other preys of interest to large predatory fishes. The two most popular types of spinnerbaits are the in-line spinner and safety pin spinnerbait, though others such as the tail spinner also exist. Spinnerbaits are used principally for catching freshwater fishes such as perch, pike and bass.
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.
A dropline is a commercial fishing rig consisting of a long fishing line set vertically down into the water, with a series of baited hooks attached to the ends of side-branching secondary lines called snoods. Dropline fishing, or droplining, is a specialized angling technique.
A sabiki or flasher rig is typically fished off boats, piers, jetties, or any structure over the water. Sabikis consist of any number of small hooks, each one on individual dropper lines that are a few inches long. The individual dropper lines are then tied to a longer leader in series, about 6 inches (15 cm) apart; a weight is tied to the end of the leader. Alternatively, a larger lure or plug can be used at the end. This creates the illusion that a medium-sized fish is chasing 6 to 10 smaller fish.
Surf fishing is land-based game fishing while standing on the shoreline or wading into the surf zone. A general term, surf fishing may or may not include casting a lure or bait, and refers to all types of shore fishing – from sandy and rocky beaches, rock jetties, or even fishing piers. The terms surfcasting or beachcasting refer more specifically to surf fishing from the beach by casting into the surf at or near the shoreline. With few exceptions, surf fishing is done in saltwater. The most common misconception about surf fishing is the idea that one must cast as far out as possible in order to reach the fish. At beaches on the west coast of the United States, and in fact, at most beaches around the world, you only really need to get your bait into knee-deep water. This is referred to as surf fishing the "skinny".
Fishing techniques are methods for catching fish. The term may also be applied to methods for catching other aquatic animals such as molluscs and edible marine invertebrates.

Kite fishing is a fishing technique. It involves a kite from which a drop line hangs, attached to a lure or bait. The kite is flown over the surface of a body of water, and the bait floats near the waterline until taken by a fish. The kite then drops immediately, signaling to the fisherman that the bait has been taken, and the fish can then be hauled in. Kites can provide boatless fishermen access to waters that would otherwise be available only to boats. Similarly, for boat owners, kites provide a way to fish in areas where it is not safe to navigate - such as shallows or coral reef.
Jug fishing is an unlimited class tackle method of fishing that uses lines suspended from floating jugs to catch fish in lakes or rivers. Often, many jugs are used when jug fishing. In many states, a fisherman could use up to twenty, and jug sets of around twenty are common in practice. Jug fishing is most common in southern states of the US. Jugs are often put out at sunset and picked up at sunrise by the whole family. Jug fishing consists of a simple setup where lines are tied onto jugs and weights can be added to the line to keep the jug's location fixed. Jug fishing is also subjected to numerous state and local water regulations that could include: the number of jugs, dates and times when jug fishing is allowed, and if jug fishing is even allowed. Many fish can be caught on jugs, but the main target of jug fishing is often catfish.
Crab traps are used to bait, lure, and catch crabs for commercial or recreational use. Crabbing or crab fishing is the recreational hobby and commercial occupation of fishing for crabs. Different types of traps are used depending on the type of crab being fished for, geographic location, and personal preference.
Fishing gear and methods used in Uganda are both modern and traditional. Fish in Uganda are caught mostly with plank canoes and to a lesser extent, fiberglass boats. Some dugout canoes are also still being used. The plank canoes are generally 4–12 m (13.12–39.37 ft) in length and dugout canoes average 3.5 m (11.48 ft). The total number of vessels is about 17,000 and about 20% of these are motorized. Artisanal fishermen use various gear including gillnets, seines and hook and line. In a number of localities, traditional methods including baskets, traps and mosquito nets continue to be used. The gear commonly used includes gillnets, lift nets, scoop-nets used in light fishing; hook and line gear and fish traps.
