Ctenopharyngodon idella (Valenciennes, 1844)

Ruohokarppi (Ctenopharyngodon idella) on noin 120 senttimetrin pituiseksi kasvava joissa elävä kala, joka on kotiseudullaan Kiinassa arvostettu ruokakala. Ruohokarppi luetaan aasiankarppien heimoon ja se on sukunsa Ctenopharyngodon ainoa laji. Se on ollut FAO:n tilaston mukaan maailmanlaajuisesti kalanviljelyssä eniten tuotettu kalalaji, ja sen kokonaistuotantomäärä vuonna 2012 oli noin viisi miljoonaa tonnia. Päätuotantoalueen Kiinan lisäksi sitä on myös istutettu ympäri maailmaa lähinnä kanaviin ja tekoaltaisiin estämään liikaa rehevöitymistä, sillä aikuiset ovat puhtaasti kasvinsyöjiä. Poikaset taas syövät vastakuoriutuneina pieniä selkärangattomia. Suomessa Ahvenanmaalla on istutettu 1970-luvulla ruohokarppeja erääseen järveen, mutta pysyvää kantaa ei ole muodostunut.
