Electrofishing is a common scientific survey method used to sample fish populations to determine abundance, density and species composition. When performed correctly, electrofishing results in no permanent harm to the fish, which return to their natural mobility state in as little as two minutes after being caught. [1]
Electric pulse fishing. The pulse trawl: electrodes in the tow direction of the gear cause an electric field above the seabed, which stimulate the flatfish so they come up toward the net. 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]

A fishing light attractor is a fishing aid that uses lights attached to structures above water or suspended underwater to attract fish and members of their food chain. Fish are typically most attracted to true-green light colors. [1] Light attractors work by taking advantage of phototactic behavior exhibited by many species of fish that are ...
A speargun is a ranged underwater fishing device designed to launch a tethered spear or harpoon to impale fish or other marine animals and targets. Spearguns are used in sport fishing and underwater target shooting. The two basic types are pneumatic and elastic (powered by rubber bands). Spear types come in a number of varieties including ...
