Background Information:
Specimen:
Perca flavescens (Fish / Yellow Perch)
Habitat:
Yellow Perches are mostly found in fresh water lakes, rivers, and streams. They require habitats with a lot of vegetation, and often live in schools (groups). Perches can live in deeper waters, but are known to reside in shallow waters during the summer months.
Food:
Perches are most actively feeding at dawn and at dusk. Young Perches eat algae and plankton, but once they mature are able to consume larger prey. An adult Perch's diet mostly consists of aquatic insects, crayfish, snails, mussels, and worms.
Respiration:
As with all other fish, the Yellow Perch gets it's oxygen by taking in water through it's mouth and filtering it out through it's gills. As water is carried through the walls of the gills, dissolved oxygen moves into the blood and travels to the fish's cells.
Fun Fact:
A notable feature of the Yellow Perch is it's large, spiny fins. These fins allow the fish to steer through the water without having to roll around. The Yellow Perch is a quick swimmer because of it's powerful fins and streamlined body shape that help it glide through the water.
