|Scientific Name:||Cottus gobio|
|Species Authority:||Linnaeus, 1758|
|Taxonomic Notes:||Considering its wide range and the observed morphological diversity, future research on C. gobio is likely to show that it is in fact an assemblage of several species.|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Reviewer/s:||Kottelat, M. & Smith, K.|
A widespread species with no known major widespread threats, however several populations are locally threatened. Future research on C. gobio is likely to show that it is in fact an assemblage of several species and each should be re-evaluated.
European Union 27 = LC. Same rationale as above.
|Range Description:||Northern Baltic basin in Scandinavia south to stream Maurine (53°51'N 10°56'E) in southwesternmost corner of Baltic basin (Germany). Lower reaches of streams and rivers and along coast of Sweden, Finland, Russia southwest to Estonia. Danube (except upper tributaries Save and Arges), Elbe, Ems, Weser and Rhône drainages. Tributaries of upper Rhine downriver (northward) to about Mannheim. A few of the uppermost tributaries of River Tevere, Central Italy. Adriatic drainages, from Potenza (Italy) to Zrmanja (Croatia), except Timavo spring (inhabited by C. scaturigo). mtDNA and microsatellite data show that sculpins from the stream Steenputbeek (4°17'N 50°43'E) in Scheldt drainage represent C. gobio, suspected to be introduced. Sculpins reported from Neretva drainage (Bosnia-Herzegovina) probably also belong to C. gobio.|

|Habitat and Ecology:||
Cold, clear and fast-flowing water of small stream to medium-sized rivers. As well on gravel or rocky shores of cold lakes and in slightly brackish waters along eastern Baltic coast.
Spawns for the first time at 2-4 years. Spawns in March-April, when temperature rises above 12°C. Females spawn once a year. Most individuals spawn for several years. They lay adhesive eggs in a compact clutch on ceiling of small cavities in gravel or rock bottom. Males guard eggs until hatching; a single male may guard the egg clutches of several females. Feeds on a wide variety of benthic invertebrates.
|Major Threat(s):||No major threats known.|
|Conservation Actions:||No information available.|
