Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; depth range - m (Ref. ), usually - m (Ref. ). Subtropical; 0°C - ; 43°N - 40°N, 19°E - 21°E
Europe: Adriatic basin from Drin to Aoos drainages. Introduced in Serchio (Italy), Garonne and Var (France) drainages, and probably elsewhere.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 18.0 cm SL male/unsexed; (Ref. 59043); max. published weight: 70.00 g (Ref. )
soft rays: 8 - 10. Diagnosed from Pachychilon macedonicum by having numerous dark brown marks of various shapes and sizes on body (a dark stripe distinct in life in juveniles, rarely in preserved individuals), thick lower lip with a long median lobe, 40-44 + 2 scales on lateral line, and 8-10½ branched rays on anal fin (Ref. 59043). Caudal fin with 19 to 20 soft rays (Ref. 40476).
A gregarious species which inhabits near shore lakes and slow-flowing stretches and backwaters of streams and rivers (Ref. 59043). Feeds on fish, invertebrates (Ref. 26100), insect larvae and periphyton (Ref. 59043). Spawns over gravel beds or among vegetation at temperatures above 12°C (Ref. 59043).

Bayesian length-weight: a=0.00776 (0.00374 - 0.01613), b=3.13 (2.96 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.8 ±0.30 se; based on food items.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
