Gizani inhabits most of the streams, springs and small water reservoirs
of Rhodes island.
In the past, gizani populations were recorded in the streams of
and Argiros, at the area of Psinthos (Pelemonis
river system), in an artificial water reservoir at Agia
Eleoussa village, in the area of Asklipion village (Kontaris
stream), in the lake of Nani, as well as
in the artificial lake Apolakkia and inflowing
New data (collected during the gizani LIFE-Nature project), showed
that the fish is extinct in lake Nani,
while it doesn't occur in the artificial lake of Apolakkia
and in the Platis and Asklipios streams.
Gizani presence was confirmed in all the rest of the water
systems mentioned above. Furthermore, populations not previously
recorded, were discovered in the streams of Chas,
(in the eastern part of the island), Kremastinos
and Paradisiotis (in the western
part). Translocation of gizani from Loutanis and Gadouras streams
to two water reservoirs of Atsaka area
was also recorded.
