Trouts in Montenegro
There are two major watersheds in Montenegro, the first
belonging to the Danube basin, principally draining first
into the Sava, and the second discharging via Skadar lake
into the Adriatic Sea. The main Adriatic draining rivers
are the Morača, Zeta and Bojana, whilst the rivers Tara,
Lim, Cehotina and Piva are the main watercourses of the
Danubian basin in Montenegro.
Trout in Montenegro are extraordinarily diverse in their
morphology, behavior and ecological characteristics; this is
probably one of the main reasons why they were of such
great interest historically to many investigators. The
first manuscript mentioning Montenegrin trout was written
by Heckel & Kner in 1858. From thereafter trout from
Montenegrin rivers attracted many other investigators.
Dr. Stanko Karaman, a well known ichthyologist from the
former Yugoslavia Republic, who invented a highly
controversial classification for different Balkan trout
lineages, got some of his inspiration when studying trout
diversity in Montenegro. He described two new species in
Montenegro (Salmo taleri in 1932, and Salmo
montenigrinus in 1933), which have never again been
confirmed. Most importantly, in 1962, Hađišče described a
new subspecies of softmouth trout from the Zeta river,
Salmo (Salmothymus) obtusirostris zetenzis. Another
interesting issue refers to Salmo dentex that
was first described by Heckel in 1851 in the rivers
Krka, Cetina and Neretva; according to the literature
(Taler, 1954; Drecun, 1958; Vuković, 1963; Ivanović,
1973), this species occurs also in Montenegro in Lake
Skadar and its tributaries, referring to a distinctive
trout named "strun" by the local population
Despite the apparent complexity and disputed taxonomy
of Salmo in Montenegro, no systematic study has been
undertaken to resolve the legitimacy of the various
operational taxonomic units. One of the main goals of
the Balkan restoration group has been therefore to
describe the genetic structure of trout populations
in Montenegro (via the use of mtDNA as well as other
genetic markers), and determine the degree of concordance
between genetic relationships and currently recognized
operational taxonomic group based on previous
morphological observations (i.e., with proposed
Salmonids inhabiting the Danubian drainage system
- Grayling (Thymallus thymallus), native
- Huchen (Hucho hucho), native
- Brown trout, (Salmo trutta), native
- Rainbow trout (Oncorhynchus mykiss), introduced
- Brook trout (Salvelinus fontinalis), introduced
Salmonid taxa inhabiting the Adriatic drainage system in Montenegro:
- Grayling (Thymallus thymallus), introduced in upper course of river Morača
