Perca Fluviatilis or Perca Flavescens?

A perch is usually used when referring to one of two species of fish, the common perch (Perca Fluviatils) and the yellow perch ( Perca Flavescens). The perch falls under the phylum Chordata, class Actinopterygii, subclass Neopterygii, and order of Perciformes. Though many fish are referred to as perch as a common name, to be considered a true perch, the fish must be of the family Percidae. Even though Perch can be found all over the world, they are most likely found in the Great Lakes, Particularly in Lake Erie.


In this lab, students will work in groups and learn from the dissection of a Perch. Students will observe the placement of organs and their relationship to one another.

Circulatory System

The circulatory system of a Perch begins with the organs involved. This list includes, a 2 chambered heart, arteries, gills, capillaries, and veins. The heart has one atrium and one ventricle. The heart pumps deoxygenated blood from itself to the gills. From there it is oxygenated and sent out through the rest of its body.
