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 ...
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.
Chod rig. The chod rig is a fishing rig for carp fishing, generally regarded as having three main advantages: the way in which it allows a bait to be displayed over soft mud, weed or debris; and the way its distinct shape allows the chosen bait (usually a buoyant substance) to be attached. The latter benefit is also generally utilised in the ...
Electrophorus electricus is the best-known species of electric eel. It is a South American electric fish. Until the discovery of two additional species in 2019, the genus was classified as the monotypic, with this species the only one in the genus. [2] Despite the name, it is not an eel, but rather a knifefish. [3]
A payao is a traditional fish aggregating device from the Philippines. [1][2] Payaos are traditionally floating rafts of bamboo anchored to the seafloor, with submerged weighted palm fronds beneath it. They were harvested using handline fishing, surface trolling, or small-scale purse seining. Modern steel payaos use fish lights and fish ...
The Maryland darter is a member of the genus Etheostoma and a member of the darter family of fishes. A relative of the yellow perch (Perca flavescens) and walleye (Sander vitreus), the Maryland darter is a bottom-dwelling fish. Ideal habitat consists of highly oxygenated, swiftly flowing portions of streaming containing moderate amounts of ...
An electric fish is any fish that can generate electric fields, whether to sense things around them, for defence, or to stun prey. Most fish able to produce shocks are also electroreceptive, meaning that they can sense electric fields. The only exception is the stargazer family (Uranoscopidae). Electric fish, although a small minority of all ...
