摘要： A device for removal of sediment particles from the water in a cultivating tank for aquatic organisms. The cultivating tank has a cylindrical outlet connected to an outlet tube located on the vertical axis of symmetry of the cultivating tank. A plate is spacedly positioned above the upper edge of an annular chamber formed at the bottom of the tank around the outlet to form a slotted opening into the annular chamber. The annular chamber has a separate outlet formed in or near the bottom for carrying away particles accumulated within the chamber. The portion of the cylindrical outlet near the upper area of the chamber includes a plurality of orifices arranged to collect and withdraw relatively clear water. In an other embodiment, the cultivating tank having a flat bottom can have a cone shaped inwardly tapering section surrounding the cylindrical outlet which forms the annular chamber. The tapering section rises inwardly to a point near a spaced circular plate so as to form a slotted opening to the chamber for removing the particles from the water. The same outlet arrangements may also be used for monitoring separate tanks within a zonal divided tank. In this way, the particle count in each zone can be monitored. The monitoring of the particular concentration within the tank is used for controlling feeding, water provision and oxygen provision for the aquatic organisms.
