double pump: (English) The process employed by fish to move water over the gills for oxygen and waste exchange. The jaw and mouth are lowered and expanded, inhaling water into the oral pump or mouth cavity. Movement outward of the operculum expands the opercular pump or cavity and valves prevent a backflow of water. The two pumps are coordinated to provide a smooth flow of water over the gills. (See also: operculum, opercular pumping, gill)
