Atlantic salmon

The Atlantic salmon (Salmo salar) is a species of ray-finned fish in the family Salmonidae.

See Fish counter and Atlantic salmon

Closed-circuit television

Closed-circuit television (CCTV), also known as video surveillance, is the use of closed-circuit television cameras to transmit a signal to a specific place, on a limited set of monitors.

See Fish counter and Closed-circuit television

Electrical resistivity and conductivity

Electrical resistivity (also called volume resistivity or specific electrical resistance) is a fundamental specific property of a material that measures its electrical resistance or how strongly it resists electric current.

See Fish counter and Electrical resistivity and conductivity

Electrode

An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air).

See Fish counter and Electrode

Electrofishing

Electrofishing is a fishing technique that uses direct current electricity flowing between a submerged cathode and anode.

See Fish counter and Electrofishing

Fish ladder

A fish ladder, also known as a fishway, fish pass, fish steps, or fish cannon, is a structure on or around artificial and natural barriers (such as dams, locks and waterfalls) to facilitate diadromous fishes' natural migration as well as movements of potamodromous species. Fish counter and fish ladder are aquatic ecology.

See Fish counter and Fish ladder

Fish migration

Fish migration is mass relocation by fish from one area or body of water to another. Fish counter and fish migration are aquatic ecology.

See Fish counter and Fish migration

Fish trap

A fish trap is a trap used for catching fish and other aquatic animals of value.

See Fish counter and Fish trap

Fishing weir

A fishing weir, fish weir, fishgarth or kiddle is an obstruction placed in tidal waters, or wholly or partially across a river, to direct the passage of, or trap fish.

See Fish counter and Fishing weir

Scotland

Scotland (Scots: Scotland; Scottish Gaelic: Alba) is a country that is part of the United Kingdom.

See Fish counter and Scotland

Sea trout

Sea trout is the common name usually applied to anadromous (sea-run) forms of brown trout (Salmo trutta), and is often referred to as Salmo trutta morpha trutta.

See Fish counter and Sea trout

Sonar

Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, measure distances (ranging), communicate with or detect objects on or under the surface of the water, such as other vessels.

See Fish counter and Sonar

Swim bladder

The swim bladder, gas bladder, fish maw, or air bladder is an internal gas-filled organ that contributes to the ability of many bony fish (but not cartilaginous fish) to control their buoyancy, and thus to stay at their current water depth without having to expend energy in swimming.

See Fish counter and Swim bladder

Wheatstone bridge

A Wheatstone bridge is an electrical circuit used to measure an unknown electrical resistance by balancing two legs of a bridge circuit, one leg of which includes the unknown component.

See Fish counter and Wheatstone bridge
