Electrofishing. Scientists carrying out a population and species survey using electrofishing equipment. Electrofishing is a fishing technique that uses direct current electricity flowing between a submerged cathode and anode. This affects the movements of nearby fish so that they swim toward the anode, where they can be caught or stunned.
Electric pulse fishing is a fishing technique sometimes used in trawl fisheries which produces a limited electric field above the seabed to catch fish. [ 1] The pulse trawl gear consists of a number of electrodes, attached to the gear in the tow direction, that emit short electric pulses. The electrodes replace the tickler chains that are used ...
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.

In physics, an effective field theory is a type of approximation, or effective theory, for an underlying physical theory, such as a quantum field theory or a statistical mechanics model. An effective field theory includes the appropriate degrees of freedom to describe physical phenomena occurring at a chosen length scale or energy scale, while ...
Electric fishing. Electric fishing can refer to one of two methods of fishing: Electrofishing, used to draw fish to an anode to be captured. Electric pulse fishing, where an electric pulse is generated above the sea bed to disturb fish to be captured.
Electrofishing – uses electricity to stun fish before they are caught. Shrimp baiting – Shrimp baiting is a method used by recreational fisherman for catching shrimp. Dredging – A fishing dredge, also known as a scallop dredge, oyster dredge, etc., is a kind of dredge which is towed along the bottom of the sea by a fishing boat in order ...
Basnig or balasnig are lift nets (salambaw) operated by a large outrigger boat called Basnigan. They use a large bag net suspended directly below or beside the ship. This net is attached to multiple temporary booms projecting from the ship's outriggers and detachable auxiliary masts. Modern basnig typically use generators and electric lights to ...
