European perch
Predatory freshwater fish native to Europe and North Asia.
The European perch (Perca fluviatilis), also known as the common perch, redfin perch, or Eurasian perch, is a predatory freshwater fish native to Europe and North Asia. It is the type species of the genus Perca and a popular game fish for recreational anglers, widely introduced beyond its native range into Australia, New Zealand, and South Africa, where it has caused ecological damage.

Lore & Background
Due to similar appearance and ability to cross-breed, the yellow perch has sometimes been classified as a subspecies, Perca fluviatilis flavescens. The perch inhabits fresh waters across Europe (excluding the Iberian Peninsula) and reaches the Kolyma River in Siberia. It lives in slow-flowing rivers, deep lakes, and ponds, avoiding cold or fast-flowing waters, and is most abundant in shallow lakes with deep light penetration. It has been widely introduced outside Europe, with adverse ecological impacts; in Australia it is implicated in the decline of the endangered Macquarie perch and is declared a noxious species in New South Wales. European perch are greenish with red pelvic, anal, and caudal fins, and five to eight dark vertical bars. They are carnivorous: juveniles feed on zooplankton and bottom invertebrates, while adults eat fish such as sticklebacks, perch, roach, and minnows. Males mature at one to two years, females at two to four years. Spawning occurs between February and July in the Northern Hemisphere, with females laying a white ribbon of eggs up to one meter long on submerged vegetation.
Reader's Guide
The European perch is significant both ecologically and economically. As a type species of the genus Perca, it serves as a biological reference for perch taxonomy. Its flesh is considered good eating, firm and mild in flavor, and is widely consumed in Europe. However, its introduction beyond its native range has had serious ecological consequences: in Australia, it has contributed to the decline of the endangered Macquarie perch and is classified as a noxious species in New South Wales. The perch is also an important prey for many predators, including the osprey, great cormorant, common kingfisher, Dalmatian pelican, northern pike, and Eurasian otter. Culturally, it is Finland's national fish and appears in the emblems of several European towns. Its life history—from spawning in spring to rapid growth and predation on smaller fish—makes it a key species in freshwater ecosystems, both native and introduced.

Frequently Asked Questions
Where does the European perch naturally live?
This species is native to freshwater systems across Europe and North Asia. It is a strictly freshwater predator and does not occur in marine or brackish environments in its native range.
How large can a European perch get?
The maximum recorded length is 60 cm (24 in), and the IGFA world weight record stands at 2.9 kg (6 lb 6 oz). Most specimens encountered by recreational anglers fall well below those extreme figures.
Why is the European perch considered invasive in some countries?
It has been widely introduced outside its native range into regions such as Australia, New Zealand, and South Africa. In those ecosystems it preys on native fish and has caused measurable ecological damage.
How long can a European perch live?
Under favorable conditions, individuals can reach a maximum lifespan of roughly 22 years. This makes it one of the longer-lived freshwater game fish in European waters.
