Diagnosed from its congeners in Aegean and Black Sea basins by having the following characters: origin of anal fin below or about ½ -1 scale behind base of last dorsal ray; lateral line with 54-63 + 4 scales; anal fin with 13-15½ branched rays; base of paired fins orange in spawning adults; 25-30 gill rakers (mode 27); length of gill raker at angle of upper and lower limbs of first gill arch 45-55% of opposite inner gill filament; ventral keel exposed for 6-8 scales in front of anus; caudal peduncle depth 10-11% SL; and nuptial males with numerous small tubercles (Ref. 59043).
Occurs in Lake Mandras drainage and migrates up to the upper reaches of lake tributaries to spawn. Spawning takes place in riffles with strong current, on gravel bottom. Forages in pelagic area of lake, close to surface. Preys on terrestrial insects and zooplankton. Threatened due to restricted range, pollution in the lake and impoundment of spawning streams. Reaches up to about 18 cm SL (Ref. 59043).
