A high efficiency recirculating marine aquaculture process for producing fish at variable yield densities of up to 60 kg/meter of the aquaculture tank, including fish that spawn under short photoperiods such as gilthead seabream ( ) as well as fish that spawn under long photoperiods such as striped bass ( ). The process involves broodstock conditioning, spawning/reproduction, larval growth, nursery, and adult grow-out operations. The process is characterized by high-rate growth at optimal process conditions requiring less than 10% daily water exchange, thereby enabling effluent waste from the system to be discharged to a municipal sewer after disinfection treatment, which in turn permits siting of the aquaculture process facility in urban/suburban locations where aquaculture processes have been previously infeasible.
