Behavior And Passage Of Silver-Phase American Eels, Anguilla Rostrata (Lesueur), At A Small Hydroelectric Facility, Alex Haro, Ted Castro-Santos, Jacques Boubee

Alexander Haro

Downstream migrant eels were monitored near a small (51 MW) hydroelectric facility on the Connecticut River (Massachusetts, USA) for two seasons using acoustic and radio telemetry. Eels frequently made several attempts over periods of one to several days to pass the station. Diel activity of eels was variable, although most movements occurred at night. Eels occupied a variety of depths in the forebay area, but spent the greater proportion of time at or near the bottom (10 m), occasionally venturing to the surface. Horizontal movements usually spanned across the entire width of the forebay. There was no significant relationship between …
