A silver-phase American Eel in a northeastern river begins migrating downstream to the ocean to spawn in the Sargasso Sea. The migration can span hundreds of kilometers in freshwater rivers and thousands of kilometers at sea.

Left: Prototype ABS plastic eel climbing ramp under development and testing at CAFRL. New substrate design allows for passage of a wider size range of eels with less need for precise flow regulation. Right: juvenile eel climbing wetted ABS plastic substrate.

Radio-tagged silver phase American Eels being released for a CAFRL telemetry study of downstream passage of eels at hydroelectric dams on the Shetucket River, Connecticut.

Prototype design of an airlift developed at CAFL to transport downstream migrant eels through a bypass pipe and away from turbine intakes. The airlift design passes eels as well as a conventional siphon or gravity pipe.

Apparatus used to test the sensitivity of eels to low-voltage pulsed DC electric fields. Knowledge of sensitivity of eels to electric fields enables development of behavioral barriers that use electricity to guide eels away from turbine intakes.
