Abstract
Hydro-acoustics is a non-intrusive method of sampling fish populations in lake ecosystems to estimate their abundance and to study their relationships with the ecosystem. It is part of the potentially usable sampling procedures of the Water Framework Directive (WFD) and is standardised (CEN 2014). At a time when the use of these methods is increasing, i) methodological advances, ii) the development of an autonomous boat (HARLE: Hydro-acoustic Autonomous boat for Remote fish detection in LakE) and iii) the response to scientific and management developed by the UMR CARRTEL in partnership with the OFB and then within the Pole ECLA (ECcosystèmes LAcustres – OFB-INRAE-USMB) are possible ways to improve the deployment of this tool for operational purposes. Indeed, the methodological works have made it possible to specify the implementation of this method in a lake environment in order to potentially amend the European standard. The HARLE has been deployed on several sites and several projects have used the acoustic data to respond to management issues or ecological questions.
