A high efficiency recirculating marine aquaculture process for producing fish at variable yield densities of up to 60 kg/meter3 of the aquaculture tank, including fish that spawn under short photoperiods such as gilthead seabream (Sparus aurata) as well as fish that spawn under long photoperiods such as striped bass (Morone saxatilis). 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.

1. A closed, recirculating marine aquaculture process for production of a marine fish species, including life-cycle stages of (i) broodstock conditioning, (ii) spawning, (iii) egg incubation, (iv) larval growth, (v) nursery post-larval growth, and (vi) grow-out of fish to a final product weight, wherein each respective life-cycle stage (i)-(vi) of the process involves operation in an aqueous medium that is coupled in liquid recirculation relationship with means for removing waste components from the aqueous medium and returning purified aqueous medium to the external environment, and wherein photoperiod, water temperature, water chemistry, and diet are optimized and then continuously monitored and controlled for the specific marine fish species, to obtain optimal production at each of the six life-cycle stages (i)-(vi).
