A pre-fabricated multi- tank system (AHAB, Pentair Aquatic Ecosystems) used for mussel propagation and host species testing at the Virginia Fisheries and Aquatic Wildlife Center at Harrison Lake National Fish Hatchery (Charles City, Virginia). This system is outfitted with a series of 1 liter tanks with individual flow control for each tank, temperature control, and biological, mechanical and ultraviolet filtration.
