Abstract: A cylinder is made of opaque material with a diameter slightly larger than the largest cross-section of the fish to be stored. Water is introduced directly into the cylinder or into a chamber which can either be attached to the outside of the cylinder or is created by placing the cylinder inside a larger diameter outer cylinder. The water enters the cylinder through perforations at a first end. The chamber may be positioned to stand vertically or horizontally with a water inlet tube and a water outlet tube through the side wall at its second end. A funnel or cone, which may have one or more perforations, is suspended pointing toward the second end within the cylinder a short distance from its second end. The incoming water flows through the perforations in the second end of the cylinder and up through the funnel perforations. As the cylinder fills, water will exit the cylinder through an outlet tube located near the first end of the cylinder.
