Status and distribution in Luxembourg

Oncorhynchus mykiss (Walbaum, 1792) (Syn: Trutta iridea (Gibbons, 1855)) was introduced to Luxembourg in 1887: “On 2 July 1887 Mr. Koltz introduced the ‘rainbow trout’ (Trutta iridea) to us and released it in the Canacherbach (Anonym 1892; Feltgen 1902). 2

During the river inventory of 1996/1997 the Rainbow trout was found in 33 spots. During a similar inventory in 2005, the species was only documented in two rivers: the Lower Syre (3 individuals) and the Reierbaach in the vicinity of Lasauvage (49 indivduals). The latter population indicates natural reproduction in the Reierbaach, which happens rarely in Europe (Administration de la gestion de l’eau 2010).

The decline of the species in Luxembourg is due to the fact that introduction of the Rainbow trout was reduced considerably with, for example, a total ban in border rivers since 1986 (Administration de la gestion de l’eau 2010).
