🐟European perch
Ahven (Perca fluviatilis) on Euraasiassa makeissa ja murtovesissä elävä kalalaji. Se on yleensä vihreäsävyinen tummilla pystyraidoilla. Sen vatsaevät ja pyrstö ovat puna-oranssit. Tyypillisesti ahven on 15–30 sentin pituinen ja 50–350 gramman painoinen ja sen elinikä on noin kuusi vuotta. Ahven on Suomen yleisin kalalaji ja Suomen kansalliskala. Se on parvikala, joka liikkuu ja etsii ravintoa päivisin parvissa, mutta yöksi se menee yksin pohjalle kasvuston suojaan lepäämään. Ahven lisääntyy tehokkaasti, ja naaras voi laskea jopa yli 200 000 mätimunaa. Pienet yksilöt syövät eläinplanktonia, mutta iän myötä ruokavalioon tulevat pohjaeläimet ja pikkukalat. Ahventa myös pyydystetään ruokakalaksi.
