The family Percidae consists of freshwater fish commonly known as perches, which include species like the yellow perch and European perch. These fish are characterized by their elongated bodies, spiny dorsal fins, and a preference for habitats such as lakes, rivers, and streams. They are popular among anglers due to their fighting ability and taste. Members of the Percidae family are typically carnivorous, feeding on smaller fish, insects, and crustaceans. They play an important role in aquatic ecosystems as both predators and prey. Many species exhibit interesting behaviors, such as schooling and nesting, which contribute to their survival and reproduction.
