WebSonars are useful for the detection of fish and biomass estimation. In recent years, high powered laser systems operating in the blue- green portion of the visible spectrum (lidar) have shown promise for the evaluation of fishery resources. A lidar carried on aircraft flying at an approximate altitude of 1700 m can detect fish at depths to 16 m. WebUltrasound is sound that has a wave frequency higher than the human ear can detect. It includes all sounds with wave frequencies higher than 20,000 waves per second, or 20,000 hertz (Hz). Animals such as bats and dolphins send out ultrasound waves and use their echoes to identify the locations of objects they cannot see.
