[57] ABSTRACT
This invention is a system for raising land and aquatic, plant and animal crops in a symbiotic-type polyculture using organic/sustainable methods of agronomy, animal husbandry, aquaculture, and hydroponics whereby yields are optimized while reducing production costs, conserving resources, and protecting the environment. Year-round production is also achieved by providing a canopy means along with additional environmental control and supplemental systems that increase yields in temperature zones normally having ambient temperature fluctuations too great to sustain production for more than a few months per year. Any number of cropping combinations are possible, but as an example, this system would establish a beneficial symbiotic-type production link between poultry, microalgae, fish and aquatic animals that consume algae, and vegetables or other land crops.
