Abstract
A fish transfer apparatus for directional positioning of fish entering a fish transfer pump reducing injury, stress and enhancing sea lice removal when coupled to a Coanda effect fish transfer pump. The apparatus employs a collection structure constructed from a funnel shaped passageway made of spaced apart bars. A manifold is positioned along an outer surface of the spaced apart bars for directing a flow of water through the passageway at a predetermined position. Fish approaching the apparatus are naturally attracted to the outward flow of water past the ring frame and will enter the passageway as they will be swimming against the current. Once the fish passes the manifold, the fish is subject to the suction caused by the fish transfer pump and drawn into the suction pipe for transfer.
