Entries for Fish Protection

Invisible field guidance system utilizes pulsed electrical fields at vertical electrodes to guide fish past water diversions and intakes.

Bladeless HydroChutes are a fish-friendly, low-cost way to extract energy from wild rivers. HydroChutes use no hazardous materials.

A special designed pipe, that is buried in the river channel 1to 2 feet deep, water is draw into the pipe naturally without fish & fish eggs

Artificial intelligence to detect and divert fish towards preferred pathways and away from areas like dams, canals, diversion pipes.

Funny fish communicating through the non physical barriers and briding the gap through physical barrier condtioning their behavior

A physical or combined physical/electrical device designed to guide fish to the safest path through a hydropower intake or water diversion.

Bio-inspired bi-stable self-powered fish tag for close-loop fish exclusion.

The FERS is designed to be installed at either an angle to guide or parallel to exclude bottom-oriented fish from intakes.

An efficient new bar shape for fish exclusion screens inspired by filter-feeding fish. To be developed using computer models & lab flume.

Improvement of current fish diversion implementations by developing acoustically sensitive materials to facilitate easier inspection.

Design proposed where the fish are separated from the water flowing through the penstock and eventually reaching the turbine.

A floating separator is proposed for fish exclusion, diverting fish species back to their natural environment, leveraging the Coandă effect.

Electromagnetic longitudinal wave barrier as a sensory deterrent system to prevent penetration of fish inside of intake canals & streams.
