ABSTRACT:
Method and apparatus for the aquaculture of aquatic, non-air breathing, carnivorous animals, wherein a generally enclosed body of water is established, and aquatic non-air breathing, carnivorous species to be reared is disposed in said body of water, a filter-feeding aquatic non-air breathing species is also disposed in said body of water, and an aqueous euphotic zone containing phytoplankton is established in said body of water; the excreta from said carnivorous and filter-feeding species providing nutrients to said phytoplankton, said phytoplankton at least in part providing the food for said filter-feeding species, and said filter-feeding species at least in part providing the food for said carnivorous species.
The water in said enclosed body is circulated so as to move water from below said euphotic zone to within said euphotic zone so that settling nutrients and phytoplankton are returned to the euphotic zone for maximum photosynthetic production of protoplasm in the system, and to avoid eutrophication in the lower levels of the body of water resulting from phytoplankton death and bacterial action on the nutrients. Such circulation may, according to the invention, be provided by energy from sea water, either from its higher specific gravity than fresh or brackish water, or from tidal action, or both.
Sea water is utilized according to the present invention in combination with fresh water to provide brackish water at least in said euphotic zone for optimum growth conditions of all three principal life forms, the phytoplankton, the filter-feeding species, and the carnivorous species. A fresh water lens or blanket may be spread over the top of the more dense brackish water during the cold season to provide a "greenhouse effect" maintaining the body of water within the desired temperature range for the growth cycle of the system.
