Importance and distribution in Luxembourg

In Luxembourg, the species has first been documented as early as 1892 (21st January 1892) in a pond in Diekirch (Bull. Soc. Nat. luxemb. 1892 cit. in Feltgen 1902). In 2005, two adults and 300 juveniles were caught in the Moselle river in Stadtbredimus while some 500 juveniles were observed the same year in the marina near Schwebsange. No other river seems to be populated by the species.

The brown bullhead is a fish species that lives in standing and slow-running waters where it can cope with low oxygen levels, water pollution and high temperatures. The omnivorous species can form very dense populations and is able to dominate freshwater fish communities. The diet of large-sized bullheads has been found to consist almost exclusively of juvenile fishes. Although there is some concern about its strong competitive and predatory ability, it is difficult to find hard evidence of species displacement or ecosystem disruption.
