Perca fluviatilis: The scientific name of the European perch, a species in the family Percidae. This binomial identifies the species across scientific descriptions and taxonomic records.
Fish predation: The capture and consumption of animals by fish. Perch shift from small invertebrate prey toward fish as they grow.
Recreational fishing: Fishing undertaken for leisure rather than primarily for commercial sale. European perch are a popular target for anglers across much of their range.
Yellow perch: A North American freshwater fish in the genus Perca, marked by dark vertical bars. It resembles European perch but is a distinct species native to North America.
