The fish learn to hit a rod that releases the food. Each raceway has its own recirculation system in which about two-thirds of the water is recycled. The water in the raceway is completely exchanged every hour. The partitions you may see in the raceways do not extend to the bottom, so fish can freely travel up and down the length of the raceway. These baffles help to create a higher water velocity near the bottom to sweep it clean of debris.
All incoming water is aerated by the red towers at the south side of the raceways.
Each tower contains a series of aluminum baffles over which water cascades. This allows for oxygen to be added before water is delivered to the raceways. The large hatchery building holds fish incubation and start tank equipment, electrical monitoring and control equipment, water filtering equipment, a lab, offices, and a shop area. The mechanical room houses three large sand filters that clean the water used inside for hatching and growing fry. The incubation room consists of four hatching racks, a spawn area, and 16 large catch tanks.
