Electrofishing uses direct current electricity flowing between a submerged cathode and anode. This affects the movement of the fish so that they swim towards the anode where they can be caught.

Electrofishing is a common technique used by fisheries biologists to sample fish populations in bodies of freshwater. As the name implies, electrofishing uses electricity to catch fish.

By Patrick Cooney While hook and line fishing is the most popular method of catching fish by freshwater anglers, electrofishing is one of the most popular methods used by fisheries biologists.  But what exactly is electrofishing, and how is it done properly?

A fish aggregating (or aggregation) device (FAD) is a man-made object used to attract ocean going pelagic fish such as marlin, tuna and mahi-mahi (dolphin fish). They usually consist of buoys or floats tethered to the ocean floor with concrete blocks. Over 300 species of fish gather around FADs. FADs attract fish for numerous reasons that vary by species.

Dredging is the removal of material from the bottom of lakes, rivers, harbors and other water bodies.

Dredging is the process of removing silt from the floor of any ocean body in order to make the waters easily accessible for ships and other types of vessels.

Night fishing can be an exhilarating experience. It's a fun activity full of mystery and expectation. When will something take the bait? What will it be? Will I overcome it, or will it overcome me?

Why a fishing light attractor? Whether you are interested in watching lots of fish, or catching more fish than you thought possible you should explore the benefits of a fishing light attractor.

A payaos is a type of fish aggregating device used in Southeast Asia, particularly in the Philippines. Payaos were traditionally bamboo rafts for handline fishing before World War II, but modern steel payaos use fish lights and fish location sonar to increase yields.

This paper presents the profile of different fisheries that depend on payao (floating artificial reef) in the Philippines. In 2006, payao fisheries production was estimated at about 630,000 Mt, and la

Shrimp baiting is a method used by recreational fisherman for of catching shrimp. In the 1980s the sport became popular in the southeastern coastal states of North Carolina, South Carolina, Georgia, and Florida. Since then, several local state regulations have been implemented to better regulate catch limits, methods, and seasons.

It’s September in South Carolina – the season of school bells, tropical storms, and, for some crustacean-crazy folks, shrimp baiting.

When fishing for crustaceans or shellfish, a Saltwater Recreational Fishing License is required - unless you are using 3 or fewer drop nets, 3 or fewer fold up traps, or 3 or fewer handlines with no hooks and a single bait per line (chicken necking); or shrimp baiting (which requires a shrimp baiting license).

During shrimp baiting season, Sept. 14-Nov. 14, a $25 license from the S.C. Department of Natural Resources allows recreational shrimpers to collect a 48-quart cooler full of the tasty crustaceans each night – and boatloads of memories.

“Laksegiljer” are small cabins standing on stilts where a fisherman sits. This method of fishing entails a net where the opening is controlled by a line tied...

Blast fishing or dynamite fishing is the practice of using explosives to stun or kill schools of fish for easy collection. This often illegal practice can be extremely destructive to the surrounding ecosystem, as the explosion often destroys the underlying habitat (such as coral reefs) that supports the fish.

Includes: the process of blast fishing, the purpose of blast fishing, prevalence and legality of dynamite fishing, environmental impacts of blast fishing, and blast fishing in the future.

Bottom trawling is trawling (towing a trawl, which is a fishing net) along the sea floor. It is also referred to as "dragging".

Overfishing – catching more fish than the ocean can produce – has been an ongoing challenge for fisheries managers for decades.

Bottom trawling destroys far more ocean habitat than any other fishing practice on the West Coast. In this fishing method, large weighted nets are dragged across the ocean floor, clear-cutting a swath of habitat in their wake. Some of these scars will take centuries to heal, if ever. For example, hard corals in Alaska have been dated to be hundreds to thousands of years old, and radio carbon dating on the oldest known deep sea corals indicates they are 4,200 years in age. Yet, these pillars of the ecosystem can be destroyed by one swipe of a bottom trawl.

Aside from possible effects on human health, cyanide fishing inflicts damage on the coral reefs where it is employed, as the poison kills the reefs and many of the life-forms that rely on them

Cyanide fishing is a method of collecting live fish mainly for use in aquariums, which involves spraying a sodium cyanide mixture into the desired fish's habitat in order to stun the fish.

Up to 90 percent of tropical aquarium fish imported to the U.S. are caught using cyanide. A new petition is calling for the government to crack down.

The muro-ami fishing technique, employed on coral reefs in Southeast Asia, uses an encircling net together with pounding devices. These devices usually comprise large stones fitted on ropes that are pounded into the coral reefs.

A description is given of the Japanese muro-ami fishing gear, which although is very effective in catching elusivereef fish, causes considerable reef damage during its operation.

Fishing is one of the world's oldest activities, merely a hobby for some and a way of life for others. While some fish strictly as a form of recreation using a dependable fishing rod and reel, some are in it to make a living, and yet others simply need to feed their families.
