Anatolia occupies a highly significant position
globally in terms of biological diversity due to its numerous closed lake
basins and independent river systems. So much so that three of the globally
identified 36 hotspots (Mediterranean, Irano-Anatolian, and Caucasus) intersect
in Anatolia. Hosting many native and endemic species of freshwater fish,
Anatolia has also seen the introduction of alien species, some of which have
successfully established populations in our waters, exhibiting invasive traits.
Çıldır Lake, one of our largest freshwater lakes, holds immense value both for
the Turkish ecosystem and for the local population. Located within the Aras
River drainage basin, the lake harbors numerous native fish species, among
which the crucian carp (native Cyprinus carpio) stands out as the most
prized by fishermen. Through stocking efforts, the lake also hosts the common
carp (C. carpio, alien), and the Prussian carp (Carassius gibelio),
a species that has colonized nearly every aquatic ecosystem in our country.
Upon examining records reported in the region to date, no evidence of the
presence of the crucian carp (Carassius carassius) has been found. In
this study, the morphological distinguishing features of an individual captured
with a trammel net in Çıldır Lake were examined, and it was determined that
this individual belongs to the Carassius carassius.
