1. An aquaculture installation comprising:

  • a plurality of cage modules, each having a framework sufficiently strong to withstand open sea currents, each module having an open cage structure over at least a portion of its surface area, and each cage having a weight and air reservoir structure which causes the module to float in an open sea environment with at least a lower portion of its cage structure submerged below the surface,said plurality of modules being located in an open sea having currents in surface layers, which currents are essentially unconfined by sea boundry structures,each module containing therein the fish life which creates fish pollution, primarily fish dejecta, which is carried away by the said currents in the surface layer, the pollution carried away by the said currents being located in a zone of action, which zone extends substantially parallel to and in the direction of said current from each cage, downstream therefrom, and a certain width transverse to the direction of said currents, the modules of the plurality thereof being spaced apart in a direction transverse to the mean direction of said currents a sufficient distance that the zones of action of two adjacent modules are free from overlap with each other.
