Application of sonar technology to fisheries acoustics has made significant advances over recent decades. The echosounder systems evolved from the simple analog single-beam and single-frequency systems to more sophisticated digital multi-beam and multi-frequency systems. In this paper, a brief review of major technological advances in fisheries acoustics is given, as well as examples of their applications.
