Pulse fishing is a fisheries management technique for preventing fish stocks from being overfished by periodically permitting a cycle of fishing followed by a fallow period which allows stocks to reconstitute. [1] It should not be confused with electric pulse fishing which is a fishing technique which involves pulsing electric currents. [2]
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.
When using pulsed DC for fishing, the pulse rate and the intensity of the electric field strongly influence the size and nature of the catch. The conductivity of the water influences the shape and extent of the electric field and thus affects the field's ability to induce capture-prone behavior in the fish. It can also cause injury to the fish.

Seine fishing (or seine-haul fishing; / s eɪ n / SAYN) is a method of fishing that employs a surrounding net, called a seine, that hangs vertically in the water with its bottom edge held down by weights and its top edge buoyed by floats. Seine nets can be deployed from the shore as a beach seine, or from a boat.
Biomass estimation is a method of detecting and quantifying fish and other marine organisms using sonar technology. [1] An acoustic transducer emits a brief, focused pulse of sound into the water. If the sound encounters objects that are of different density than the surrounding medium, such as fish, they reflect some sound back toward the source.

When fishing from a sea-going boat, groundbait known as "chum" is commonly used to attract fish. Brown Trout. In North America, popular freshwater fish include trout, bass, pike, catfish, walleye and muskellunge. The smallest fish are called panfish, because they can fit whole in a normal cooking pan, examples being perch and sunfish ...
