ABSTRACT:
A system for aqua farming comprises at least one land mass; typically a plurality of approximately rectangular land masses with their sides typically at least about an order of magnitude longer than their ends and defining approximately parallel channels between them in an adjacent body of water. The water moves into the channels and, in a substantial region of each land mass, also moves through it from the channel on one side to the channel on the other side thereof. Filtering means such as sand, gravel, or a mixture of sand and gravel, block the movement through the land masses of most of the pieces of solid matter that may be present in the water, whose smallest cross section is larger than a predetermined size.
