ABSTRACT:
The present invention is an improved method of growing a biomass in an aquaculture medium comprising enclosing the aquaculture medium containing seed amounts of a biomass in an enclosure in which the medium containing the biomass fills one-half of the enclosure and a CO.sub.2 and air gaseous layer is above the medium and fills the other one half, growing the biomass in the medium within the enclosure in a predetermined growing cycle enhancing growth of the biomass in the medium by exposing it to continuous agitation by agitation means heat, by heating means, and illumination by a light source capable of causing photosynthesis in the biomass, and whereby CO.sub.2 consumed from the medium and gaseous layer during photosynthesis in the biomass is continuously replenished by a CO.sub.2 enrichment means and oxygen produced to the medium and gaseous layer during photosynthesis is extracted by extraction means.
