Life of a Perch
ocean to dissection
Perch belong to the kingdom Animalis under the phylum chordata. Their class is the actinopterygill, with the order perciformes. They belong to the Percidae family and have the perca genus.
Largemouth bass grow 4 to 6 inches during their first year, 8 to 12 inches in two years, and 16 inches in three years.
Perch prefer to live in slow -moving, clear, fertile water. However; perch are very tolerant, adaptable fish. They are known for their ability to survive in low oxygen levels. This allows them to inhabit deep water where there is often little oxygen. This helps to survive winterkill conditions.

Human Impact on Perch
The gills are located directly under the operculum. The 4 layers of gills lay directly on top of one another. The two chambered fish heart is located directly below the gills.
The esophagus leads to the stomach where the liver, which is rather large, is located. The intestine leads to the anus where wastes are disposed of. The kidneys are found just below the spinal column. The swim bladder, which helps keep the fish afloat, is found above the stomach.
