Distribution Additional InformationPomatoschistus microps is a migratory fish, except where natural or man-made barriers prevent this. In the Atlantic the common goby can migrate for spawning, moving inshore for the breeding season, or to avoid low salinities (Miller, 1975) and temperatures (Nyman, 1953; Jones & Miller, 1966; Araujo et al., 2000).

It can be found down to 11 m in depth but normally occurs at < 1 m. It may also follow the incoming tide up over mudflats. Along the coastline it moves into warmer, deeper water for the duration of winter (Barnes, 1994), in particular when sea temperatures drop below 5 °C, but not where minimum sea temperature is above 7 °C (Miller, 1975).

The common goby lives in estuary channels where current flow can be considerable. In estuaries the it migrates downstream during the breeding season and also with the onset of maturation (Miller, 1975). In the Mediterranean they tend to be less mobile.
