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 ...
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 ...
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 ...
Otter (fishing device) The otter is a fishing device constructed with two parts, an otter board and a fishing line. It is steered by pulling on the line then letting stack so the slide mechanism on the board operates to switch direction. It may be used from a boat or pulled from the shore. It is very difficult to retrieve from a boat once fish ...
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 ...
A sabiki or flasher rig is typically fished off boats, piers, jetties, or any structure over the water. Sabikis consist of any number (usually between 6 and 10) of small hooks, each one on individual dropper lines that are a few inches long. The individual dropper lines are then tied to a longer leader in series, about 6 inches (15 cm) apart; a ...
