New record of translocated Phoxinus bigerri Kottelat, 2007 from a river basin in the North-West Atlantic coast of the Iberian Peninsula

This paper provides the first report of the Pyrenean minnow Phoxinus bigerri in a small coastal river, which flows into the Atlantic coast of Galicia (NW Spain), as well as basic biometric and population data. The high density found in this survey, in addition to the presence of both young-of-the-year and the six brightly coloured males showing clear spawning characteristics, all indicate that this fish species is naturalized in the area.
