Perch Dissection Pre Ap Biology April 8th 2014
TaxonomyThe scientific name of a perch is Perca flavescens and it belongs in the Chordata phylum.
Perches live in areas near the shore with lots of vegetation to hide in. They eat larvae, crustaceans and small fish. Predators of the perch are usually larger fish, like the Walleye and Bluegill. Perches belong to the secondary consumer trophic level. Perch can live in fertile, eutrophic, and turbid water.
Perches have gills so they can breath underwater. They also have scales to protect the perch against predators. Perch can filter out zooplankton with filters located in their gills. They have also developed specialized fins to help them move around in the water.
Water pollution like sewage, oil, and litter could harm the perches. Fishing can also harm them.
