FIRST RECORDS AND DESCRIPTION
OF Cobitis elongata HECKL & KNER
1858 (COBITIDAE) IN MONTENEGRO
Drago MARIĆ[1]
& Vesna PAVLOVIĆ[2]
In June 2005 Balkan Loach Cobitis
elongata Heckel & Kner 1858 was caught for the first time in Montenegro
in the River Lim (the Danube Basin). We sampled 21 specimens and on six (6) we
measured 27 morphometric and 4 meristic characters. Fifty eight specimens of Cobitis elongata were
collected from several spots on the Lim River downstream the city of Berane and
its tributaries, the Bistrica and the Lješnica, in October 2005.
C.
elongata prefers habitats with
weaker flow rate, respecively lower velocity of water, which is characteritic
for the lower course of the Lim River. The habitats in which it has been found are gravelly, sometimes
with larger fractions, and rarely below the roots of woody plants.
Key words: Cobitis elongata,
morphology, distribution, the Lim River, Montenegro
PRVI
NALAZI I OPIS Cobitis elongata HECKL
& KNER 1858
(COBITIDAE)
U CRNOJ GORI
U junu 2005. godine u rijeci Lim (Dunavski sliv) po prvi put u Crnoj Gori
ulovljen je balkanski vijun Cobitis
elongata Heckel & Kner 1858. Sakupili smo 21 primjerak i na šest (6)
smo izmjerili 27 morfometrijskih i 4 merističke karakteristike. U oktobru 2005. sakupljeno je 58
primjeraka Cobitis elongata na
nekoliko lokaliteta na Limu nizvodno od Berana i na njegovim pritokama Bistrici
i Lješnici. C. elongata preferira
staništa sa slabijim stepenom protoka, odnosno sa manjom brzinom vode,
karakteritičnom za donji tok rijeke Lim. Staništa u kojima je nađen
su pjeskovita, ponekad sa krupnijim frakcijama, a rijetko ispod korijenja
drvenastih biljaka.
