Movement patterns of seaward migrating European eel ( Anguilla anguilla) at a complex of riverine barriers: implications for conservation
Abstract River infrastructure such as weirs and hydropower stations commonly present migrating fish with multiple potential passage routes. Knowledge of the cues fish use to navigate such environments is required to protect migrants from hazardous areas and guide them towards safe passage; however,...
