Objectives

The objective is to learn the internal and external anatomy of a perch. In dissecting the perch we are to identify the organs. It is important to locate the organs because it will give us a further understanding of how the perch lives.

Easily identified by the golden yellow coloration on their sides and six to eight dark bands running vertical on the sides. Perca flavescens means Yellow Perch in English.

Human Impact on Perch

Humans have had a large impact on the development and evolution of perch. The evolution of perch varies in different ecosystems. The Nile Perch has recently been transplanted into the Ugandan waters of lake Victoria. The fisheries built on those waters have had a large impact on the lives of those perch. Perch in ecosystems near pollution have evolved to survive in those polluted waters.
