Abstract
Abstract Method and apparatus are disclosed for transferring live fish from one body of water to a retaining container and then to a second body of water. The method comprises flowing a stream of water containing entrained fish under a pressure differential into a retaining container where the fish are strained out and the water stream is removed continually. The fish are released subsequently from the retaining container by reversing the flow of water into and out of the retaining container. The apparatus comprises a container attached to one end of a conduit with the other end of the conduit immersed in the water body source of fish. Other conduit means are attached to the container as well as a pump so that water may be flowed from the container or into the container. A strainer is mounted over the outlet of the container and an air-release valve and aspirator are mounted near the top of the container.
