Fish Detection Using Electrical Impedance Spectroscopy
IEEE Sensors Journal, 2022 Fish detection in shallow water conditions or close to the bottom poses specific challenges, which often can hardly be addressed using typical acoustical or optical means. This significantly limits the possibilities of fish population monitoring and the use of fish detection for optimizing fishing techniques in such environments.
