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 ...
Electrofishing - is another recently developed technique, primarily used in freshwater by fisheries scientists. Electrofishing uses electricity to stun fish so they can be caught.

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.
Fish aggregating device. A fish aggregating (or aggregation) device (FAD) is a man-made object used to attract pelagic fish such as marlin, tuna and mahi-mahi (dolphin fish). They usually consist of buoys or floats tethered to the ocean floor. Various types of FADs have been employed in the traditional fishing cultures of Island Southeast Asia ...

The ice jigger also known as prairie ice jigger, or prairie jigger, is a device for setting a fishing net under the ice between two ice holes, invented by indigenous fishermen of Canada in early 1900s.
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 ...
