Hauki

Hauki (Esox lucius) on sisä- ja murtovesissä elävä petokala.

Suomessa se on toiseksi yleisin kalalaji ahvenen jälkeen ja se asuttaa järviä, jokia ja Itämeren rannikkoseutuja koko maan alueella, ainoastaan pohjoisimmista käsivarresta yli 600–650 metriä merenpinnan yläpuolella olevista vesistöistä sitä ei tavata.

Kartan symbolit kuvaavat päävesistöaluetta. Symboli on asetettu päävesistöalueen keskelle. Järviwikissä ei tällä hetkellä ole mahdollista esittää vesistöalueiden rajoja.

Hauki kirkasvetisessä järvessä.

Ulkonäkö

Hauen kyljet ja kiduskannet ovat vihreäsävyiset ja niissä on erilaisia keltaisia kuvioita, vatsapuoli on valkea ja selkäpuoli lähes musta. Tummaläiskäisten evien väritys vaihtelee, ne voivat olla punertavan- tai kellertävänruskeita. Silmät ovat tummat kellertävällä ringillä. Värityksen tummuusaste vaihtelee jonkin verran: tummavetisissä ja -pohjaisissa vesissä se on tummempi ja kirkasvetisissä ja hiekka-sorapohjaisissa vesissä huomattavasti vaaleampi.

Hauen vartalo on pitkä, solakka ja poikkileikkaukseltaan pyöreähkö, evät ovat keskittyneet vartalon takaosaan. Pää on suuri ja kita valtava, leuat ovat krokotiilimaisesti pidentyneet ja hampaat ovat teräviä. Hampaita on yhteensä noin 700 ja niitä on leukaluiden lisäksi suuontelon luissa, kitalaessa ja kielessä. Vain osassa leukaluiden isojen hampaiden hammastiloissa on hammas ja ne vaihtuvat epäsäännöllisin välein.

Hauen kylkiviiva- ja näköaistit ovat tehokkaita, mutta hajuaisti on melko heikko. Kylkiviiva-aistiin kuuluvia kuoppia on myös jonkin verran kylkiviivan ulkopuolella.

Koko ja ikä

Hauki kasvaa koko ikänsä, nelivuotiaaksi asti noin 10 senttimetriä vuodessa, jonka jälkeen kasvu hidastuu. Ensimmäisenä kesänään se voi olla jo 15 senttimetriä pitkiä ja suotuisissa oloissa se voi kasvaa jopa 20 senttimetriä vuodessa. Vanhemmiten kasvu kuitenkin hidastuu, ja 15-vuotias hauki kasvaa enää muutamia senttimetrejä vuodessa. Iän lisäksi kasvua hidastavat myös huono ravintotilanne tai liian lämmin vesi sekä se mitä pohjoisemmaksi mennään, mutta pohjoisen ilmastovaikutus vähenee vanhemmilla yksilöillä.

Tyypillisesti hauki on 40–60 senttimetrin pituinen ja 0,5–2 kg:n painoinen. Se voi kuitenkin kasvaa jopa 35 kg:n painoiseksi ja 160 cm pitkäksi ja elää jopa 30-vuotiaaksi. Naaraat elävät keskimäärin vanhemmiksi ja kasvavat nopeammin kuin koiraat.

Suurimman pyydystetyn hauen kertominen luotettavasti on haastavaa, sillä suosittuna urheilukalastuksen kohteena siitä kerrotaan lukuisia kalatarinoita. Maailmanennätys on 30,5 kg 146 cm ja Suomen ennätys on 18,8 kg. Kuitenkin Suomesta kerrotaan saadun yli 20 kg:n yksilöitä ja maailmalta yli 35 kg:n yksilöitä.

Käyttäytyminen

Ravinto

Hauki turvautuu saalistaessaan näkö- ja kylkiviiva-aistiin.

Levinneisyys

Haukia tavataan sisävesistä kaikkialla pohjoisella pallonpuoliskolla. Pohjois-Amerikassa se esiintyy Alaskasta itärannikolle etelärajana Pohjois-Arizona, Pohjois-New Mexico, Pohjois-Texas, Missouri ja Maryland. Euroopassa esiintymisalueen etelärajana toimii Ranska sekä Italian ja Kreikan pohjoisosat. Keskisestä Norjasta, Kuolan niemimaalta ja Jäämeren saarilta se puuttuu, mutta sitä esiintyy koko Itämeren rannikkoalueella. Aasiassa se esiintyy entisen Neuvostoliiton alueella aina Kamtšatkan niemimaalle asti.
