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