Flowing bed method and apparatus for culturing aquatic organisms

摘要: A flow of loose solid particles (22, 22a, 22b) accumulates materials which are to be removed from a region (21, 21b) in aquatic organisms confined within liquid medium (13, 13a, 13b). The particle may form bed at the bottom organism containing that receives waste and also utilized scour walls (16) culture vessel (11, 11a, 11b). flow, gravitationally induced, travels down an inclined inner surface (18, 18a, 102) out through submerged outlet (51, 51a, 51b) while blocking escape outlet. preferably cleaned recirculated flow. While other usages possible, system is particularly adapted cultivation herbivore zooplankton, such as brine shrimp for example, protein production. High density biomasses maintained without adverse effects heretofore encountered result accumulation.
