dc.descriptionThe manual begins with a presentation of key physical principles used in fisheries acoustics and continues with a general description of the necessary equipment and its functions. An explanation is given of the acoustic equations followed by the acoustic properties of fish when occurring singly or in schools. Acoustic survey concepts are discussed prior to a description of calibration methods used to determine the electronic and acoustic parameters of the equipment. Use of the equipment in a sys tematic manner at sea leads on to the sources of error that can arise and explains how these may be removed or minimised. Finally methods are given for the collection and presentation of data in various forms, together with different ways in which to improve results by the use of statistics.
