SONAR is an acronym for "sound navigation and ranging." Active sonar describes an apparatus that transmits high frequency sound waves in water and registers the vibrations reflected back from an object. Passive sonars listen without transmitting. They are usually military (although a few are scientific). Some marine animals, such as whales and dolphins, use echolocation systems similar to active sonar to locate predators and prey.

A fishing net used to encircle surface schooling fish. During retrieval the bottom of the net is closed or pursed by drawing a purse line through a series of rings to prevent the fish from escaping. The catch is deposited on the fishing boat. The purse seine is operated by two boats, a large boat that surrounds the catch with the net and a smaller boat which anchors the net. Purse seines may be of up to 1 km length and 300 m depth.
