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 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.
Asian carp is a grouping of fishes commonly used to mean silver, bighead carp, white and black amur, [note 1] which are regarded invasive in the United States.These four species, also known as copi, are native to China where they are collectively known as qing cao lian yong (青草鲢鳙) or si da jia yu (四大家鱼, "Big Four domesticated fish") [note 2] and are farmed for food.
An electric boat is a powered watercraft driven by electric motors, which are powered by either on-board battery packs, solar panels or generators. [ 1 ] While a significant majority of water vessels are powered by diesel engines, with sail power and gasoline engines also popular, boats powered by electricity have been used for over 120 years.
Electric pulse fishing. The pulse trawl: electrodes in the tow direction of the gear cause an electric field above the seabed, which stimulate the flatfish so they come up toward the net. 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]
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 ...
