How does a yellow perch breathe?

Circle the ones that are bolded.The process begins by water in the fish's surrounding entering its mouth's. Water enters the mouth by a very effective pumping system that involves the mouth and the outer flexible bony flap that cover the gills called the operculum. This is achieved by the opening and closing of the fish's mouth as it pumps water through the gills. When the fish's mouth is open, the operculum closes and water is drawn into the fish's mouth. Conversely, when the fish closes its mouth, the operculum opens and fresh water is then allowed to flow across the gills.By: Matthew Christensen
