Water circulation apparatus and method

摘要

The present invention is directed to an apparatus that extracts the cooler deeper water with the warmer water near the surface in order to reduce the temperature of the upper layers of water within the cage. At the same time, the apparatus produces a water current at the surface that carries the harmful algae away from the set of cages. In addition, the apparatus extracts the oxygen-rich water from the surface and injects it into the deeper water that lacks sufficient oxygen content.
