Abstract: A system is described for holding dense population of filter-feeding organisms, such as free, or "cultchless" oysters and hardshell clams in a configuration opposed to currents of nutrient-laden sea water. The system consists of means that both channel currents, or water flows developed by pumping, gravity flow, or tidal forces and hold the populations in opposition to these currents. A distributing flow of water is achieved throughout the populations contained in the system so that individual members of the population may filter at optimum rates, with waste products of their filtering activities being removed by the current.The system is capable of taking tiny hatchery-derived seed and growing them to commercial maturity in a series of stages designed to optimize handling and feeding requirements at the various stages. At the stages where the organisms are approaching commercial maturity and require a greater current flow and more nutrients, the system is capable of developing an increased level of efficiency in regard to the utilization of resources of current flow and nutrients. At its most efficient level, the system contemplates harvest of a phytoplankton resource of any estuarial area at optimum sustainable levels.

Abstract translation: 描述了一种系统，用于保持密集的过滤器生物群体，例如与营养充足的海水潮流相反的配置中的游离或“无栽培”牡蛎和硬壳蛤。 该系统包括通过泵送，重力流或潮汐力产生的通道电流或水流的手段，并且使群体与这些电流相对。 在系统中包含的整个群体中实现水的分配流，使得群体的个体成员可以以最佳速率过滤，其过滤活性的废物被当前的消除。
