Fisheries acoustics Wikipedia

Basic Theory. Biomass estimation is a method of detecting and quantifying fish and other marine organisms using sonar technology. 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.

Echo Sounder an overview ScienceDirect Topics

The echo reflected from the bed is also received by the echo sounder. The time interval between the emission of the sound pulse and its return as an echo is used to estimate the depth of the water. The echo sounder is capable of recording a continuous profile of the reservoir bed. Typically, the accuracy of the order of several cm can be
