Abstract
PURPOSE: To eliminate the need for the installation of a power apparatus or the like needed to feed and drain water, by enabling a live well for fish to be forcibly supplied with outside water and forcibly drained by utilizing the outboard flow being caused by steaming.
CONSTITUTION: A feed water passage 2 is provided on the bow side of a live well 1 for fish. Said feed water passage 2 is provided with an on-off valve 3. Thereby, a forced feed water apparatus 4 is constituted. Accordingly, opening the on-off valve 3 during sailing permits the outboard water to be forcibly fed into the live well 1 for fish. In addition, on the stern side of the live well 1, a rising duct part 5a rising from the bottom of the live well 1 and a descending duct part 5b extending downward from the upper end of the rising duct part 5a are provided. Moreover, a drainage apparatus having an on-off valve 6 and an air supply passage 7 for introducing the atmospheric air is provided.
