Ecological Adaptations

The yellow perch has many adaptation that help it survive in diverse areas such as fertile water, eutrophic water, and sometimes turbid water. Perch also have specialized teeth called palatines that they use to eat other young fish like young large mouth bass, minnows and some insects. They can also filter out zooplankton with their gill rakers which are small filters in their gills.

Circulatory System

The perch's heart has 2 chambers: it's shape is irregular and in it are one auricle and ventricle. Deoxygenated blood from all over the body collects in the burgundy colored auricle and passes to the ventricle through the valve. The ventricle contracts and forces the blood to the gill region to be oxygenated. After being passed through the body, the blood collects in the auricle once again as it has become deoxygenated, and the cycle repeats.
