Water quality. Guidance on the estimation of fish abundance with mobile hydroacoustic methods Ingestion-build-82396 IEC 61009-1:19911 Scope This European Standard specifies a standardized method for data sampling and procedures for data evaluation of fish populations in large rivers, lakes and reservoirs, using hydroacoustic equipment deployed on mobile platforms (boats and vessels). This standard covers fish population abundance estimates of pelagic and profundal waters > 15 m mean depth with the acoustic beam oriented vertically, and the inshore and surface waters of water
