Brief description

Pimephales promelasPimephales promelas (Rafinesque, 1820), commonly known as the fathead minnow, is a small-bodied, short-lived, nest guarding cyprinid fish. It is one of the most widely distributed fishes in North America and its native range covers large expanses from the Rocky Mountains in Canada south to Texas and northern Mexico. It has been accidently or intentionally introduced to many areas, where it has been stocked for its use as bait or as an aquarium pet. It is tolerant of a range of environmental conditions, has a high reproductive output and consumes a variety of food resources. It therefore has a high invasive potential and has been recorded as a pest in many countries. It is known to cause declines of native and endangered species including Colorado pikeminnow (Ptychocheilus lucius), the Lost River sucker (Deltistes luxatus) and shortnose sucker (Chasmistes brevirostris) in Oregon and California. It has also negatively impacted habitats, such as wetlands in the Prairie Pothole Region, USA. In Europe, its introduction has resulted in the spread of enteric redmouth disease through the introduction of a bacterial pathogen (Yersinia ruckeri) (CABI 2019).

Status and distribution in Luxembourg

In Luxembourg, Pimephales promelas (Rafinesque, 1820) was first documented during a species inventory in 1996/1997 (Administration des eaux et forêts 1998). Five individuals were caught in three different spots (Lower Sauer, Alzette and Diddelengerbaach). These occurrences are probably due to the animals’ use as live bait or the release of aquarium fish.

During an identical inventory in 2005, the species was not found in Luxembourgian watercourses anymore (Administration de la gestion de l’eau 2010).

There is no distribution map available because no data has been entered into the Recorder-Lux database so far (MNHNL, iNaturalist & GBIF 2019).
