"In 2019, a sonar was installed in the Kedgwick River (Restigouche watershed) to evaluate the feasibility of using such technology to provide a count of adult Atlantic salmon (Salmo salar) swimming through the sonar field of view. This report summarises the methodology used, the challenges encountered, and the data collected during this experiment. To use this technology in a monitoring program, this exercise illustrates the need for i) a suitable location for the installation of a sonar, mainly access to direct power and a riverbed profile favouring straight swimming behaviour and ii) the need for a dedicated person for maintaining the sonar during its operation and the processing of sonar data"--Abstract, page vii.
