Brief description

Neogobius melanostomus (Pallas, 1814) is a bottom dwelling fish that lives in slow brackish and fresh waters. It is typically found near rocky substrates, but also in fine gravel and sandy bottoms. The round goby is a voracious feeder of benthic freshwater invertebrates (e.g. bivalves) and small fishes. It has been reported to reduce populations of native fish through predation and food competition, its main advantage being its ability to feed in darkness. Adults may occupy the prime spawning areas and defend those sites aggressively, keeping natives out. The round goby may rapidly become a dominant fish species and may be responsible for fish species displacement and for the impoverishment of aquatic communities (Branquart & Verreycken 2014).

Status and distribution in Luxembourg

Distribution map of Neogobius melanostomus (Pallas, 1814) in Luxembourg. Data source: Recorder-Lux, iNaturalist & GBIF, 2019-11-17.

Neogobius melanostomus (Pallas, 1814) is known to colonize the Luxembourg part of the Moselle river since around 2010. Together with Neogobius kessleri, the species was sampled regulary in the lower Sauer in the last years; in 2017 it was sampled in the Our (Dohet 2017).

Currently, 2 records of the round goby are accessible through the MNHNL-mdata portal (MNHNL, iNaturalist & GBIF 2019).

On 27th July 2015, a parliamentary question was raised in the Luxembourg Parliament about the invasion of Neogobius species in the Moselle river. This has been echoed in the daily newspaper Tageblatt on the same day (Wildschutz 2015).

The distribution map is not complete because records still have to be entered into the Recorder-Lux database (MNHNL, iNaturalist & GBIF 2019).

Risk assessment
