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. [1]

Electrofishing - is another recently developed technique, primarily used in freshwater by fisheries scientists. Electrofishing uses electricity to stun fish so they can be caught. It is commonly used in scientific surveys, sampling fish populations for abundance, density, and species composition. When performed correctly, electrofishing results ...
Traditional methods to assess fish biodiversity, [6] abundance and density include the use of gears like nets, electrofishing equipment, [6] trawls, cages, fyke-nets or other gear which show reliable results of presence only for abundant species.
Aquatic biologists utilize electrofishing equipment to estimate the number of fish in the rivers. [54] They also collect anadromous fish and donate a few to biologists from the PFBC, who check the fish for hatchery tags that mark fish released from hatcheries and distinguish them from fish born in the wild.
