Gill rakers in a perch serve primarily to filter food particles from the water as the fish feeds. These bony structures, located on the gill arches, help trap small organisms such as plankton and detritus, allowing the fish to efficiently extract nutrients. Additionally, they play a role in preventing larger particles from entering the gills, thus protecting the respiratory system. Overall, gill rakers are essential for feeding and respiratory health in perch.

The respiratory system of a yellow perch consists primarily of gills, which are specialized organs that extract oxygen from water. Water flows over the gill membranes, where oxygen diffuses into the bloodstream while carbon dioxide is expelled. The gills are supported by gill arches and covered by a bony operculum that protects them. This efficient system allows yellow perch to thrive in aquatic environments by maintaining their oxygen supply while expelling waste gases.
There are three species of the perch: Percaflavescens (Yellow perch), Perca fluviatilis(European perch) and Perca schrenkii (Balkhash perch).
