Max. size:	15.0 cm SL (male/unsexed; Ref. 4698); max. reported age: 8 years
Environment:	demersal ; depth range 0 - 15 m
Climate:	temperate; 72°N - 36°N
Global Importance:	fisheries: ; bait: usually
Resilience:	Medium, minimum population doubling time 1.4 - 4.4 years (tmax=8)
Distribution:	Europe and Former USSR: Streams in Carpathians draining to Danube, Dniestr, Vistula and Odra. Baltic Sea basin, especially in southern and northern Sweden and Finland between 64 and 68°N, central Finnish lakes areas, a few streams in southern Finland, a few lakes in northern Germany, Lake Hañcza in northern Poland and in River Skjernaa drainage in Denmark and in southern part of Lake Onega drainage.

Diagnosis:	Anal soft rays: 13-14. Differs from all other species of Cottus in Europe by possessing spatulate prickles; pelvic-fin rays tessellated, with 5-15 distinct rows of spot, appearing as transverse bands; and 2 chin pores. Additional characters useful in the identification of this species include: lateral line clearly above midline of body (shared only with C. koshewnikowi); lateral line clearly above midline of body; lateral line incomplete, usually reaching to anal-fin base; and prickling restricted to body under pectoral fin (Ref. 55856).
Biology:	Found in fast-flowing waters of coastal streams, rivers, inland lakes, usually on stony bottoms (Ref. 4698). Moves downstream to estuaries and tolerates brackish waters (Ref. 4698). Feeds on algae (diatoms, desmids, blue-green algae), polychaetes, crustaceans, aquatic insect larvae and nymphs (Ephemeroptera, Trichoptera, Plecoptera, Chironomidae), fish eggs and larvae
