Power Plants--Effects on Fish and Shellfish Behavior
Hocutt CH;Stauffer JR;Edinger JE;Hall LW;Morgan RP;
Behavioral barriers and guidance systems have been employed at power facilities in an attempt to attract or to repel fish away from intake structures. Fishes respond to stimuli by either a preference or avoidance reaction. Broad categories of behavioral stimuli which have been employed at power plants include: electrical screens, air bubble curtains, illumination, acoustics and changes in current and velocity. The ways fish orient and migrate using various environmental cues still remain largely a mystery.
