Abstract
Embodiments of the present disclosure describe aquaculture filtration systems comprising a tidal basin, first bead filter unit, second bead filter unit, and optionally an inoculation tank. The tidal basin and first bead filter unit can be in fluid communication. The first bead filter unit can be in fluid communication with the second bead filter unit and optionally the tidal basin via a bypass line. The second bead filter unit can be in fluid communication with the tidal basin and optionally an inoculation tank via an inoculation loop. The aquaculture filtration systems can optionally further comprise pumps for circulating fluids, such as circulation pumps and inoculation pumps, and valves for controlling or directing fluid flow. Embodiments also describe related methods, systems, apparatuses, and the like.
