Thinlip grey mullet Liza ramada (Mugilidae) caught in a
[摘要] Normal 0 21 false false false MicrosoftInternetExplorer4Two individuals of thinlip grey mulletLiza ramadawere collected in a southern Norwegian brook (58° 22’ N, 8° 37’ E) on 12th September 2007. The fish were 8.7 and 9.0 cm in total length, 6 and 7 g in total mass, and most probably in their first year of life. The nearest known spawning area of the species is south of the English Channel, meaning that they had probably moved at least 900km across the North Sea during their first growth season. To our knowledge, this is the first published observation of the catadromous thinlip grey mullet from a Scandinavian freshwater course.
