Description

European perch are greenish with red pelvic, anal and caudal
fins A fin is a thin component or appendage attached to a larger body or structure. Fins typically function as foils that produce lift or thrust, or provide the ability to steer or stabilize motion while traveling in water, air, or other fluids. Fin ...
. They have five to eight dark vertical bars on their sides. When the perch grows larger, a hump grows between its head and dorsal fin. European perch can vary greatly in size between bodies of water. They can live for up to 22 years, and older perch are often much larger than average; the maximum recorded length is . The British record is , but they grow larger in mainland Europe than in Britain. As of May 2016, the official all tackle world record recognised by the

s. Perch start eating other fish when they reach a size of around 120 mm. Male perch become sexually mature at between one and two years of age, females between two and four. In the Northern Hemisphere they spawn between February and July, depositing their eggs on water plants or the branches of trees or shrubs immersed in the water. There has been speculation, but only anecdotal evidence, that eggs stick to the legs of wading birds and are then transferred to other waters.


Taxonomy

The first scientific description of the river perch was made by
Peter Artedi Peter Artedi or Petrus Arctaedius (27 February 170528 September 1735) was a Swedish naturalist who is known as the "father of ichthyology". Artedi was born in Anundsjö in the province of Ångermanland. Intending to become a clergyman, he wen ...

lakes. Artedi described its features, counting the fin rays scales and vertebrae of the typical perch. In 1758,
Carl Linnaeus Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his Nobility#Ennoblement, ennoblement in 1761 as Carl von Linné#Blunt, Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalise ...
named it ''Perca fluviatilis''. His description was based on Artedi's research. Because of their similar appearance and ability to cross-breed, the

It is possible to fly fish for perch using artificial flies tied for the purpose. Often, the flies required are "streamers" or bait-fish imitations and use flash, colour and movement to entice a take from the perch.
