Europe: North Baltic in Scandinavia south to stream Maurine in southwesternmost of 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 uppermost tributaries of River Tevere, central Italy; Adriatic drainages from Potenza in Italy to Zrmanja in Croatia, except Timavo spring. Locally introduced in Scheldt drainage in Belgium. Records of sculpins from Neretva drainage in Bosnia-Herzegovina possibly belong to Cottus gobio.

生物学     用語集 (例 epibenthic)

Occurs in cold, clear and fast-flowing water of small stream to medium-sized rivers as well as on gravel or rocky shores of cold lakes and in slightly brackish waters along eastern coast of Baltic coast (Ref. 59043). Feeds on small bottom invertebrates, mainly insects, crustaceans. Pink to yellow eggs are found in clumps attached to undersides of large stones (Ref. 41678). Contrary to statements in older literature, eggs and larvae of fishes are not a common food item (Ref. 45167).

Life cycle and mating behavior 成熟 | 繁殖 | 放精 | | 生産力 | 幼生

Spawns once a year for several years in low productivity streams, but exhibits multiple spawning within a season in high productivity environments (Ref. 40290, 40754). Male protects several batches of eggs--deposited below a stone--for about 3 weeks. Larvae are not guarded and may occasionally been eaten (Ref. 45166). Also Ref. 26506.
