Abstract
An assembly designed to encourage fish to enter a Coanda effect fish pumping system to allow delousing through the pump. The process quickly decelerates the fish in a water tank to their original speed of between 1.5 to 3 feet/second depending on pumping lift for a 10 inch diameter SILKSTREAM™ pump. As the fish guiding tube enters the tank, it is surrounded by a smooth diverging cone slowing the water speed to the original fish speed. The fish are then guided by the tubular assembly away from the water and lice into a second SILKSTREAM™ intake. The current changes within the SILKSTREAM™ Coanda effect pump provide delousing of the fish by orientating the fish in a forward direction as the fish pass through the pump.
