Abstract

The round goby has established in all Baltic Sea sub-basins and is continuously increasing its range and abundance in recently colonized habitats. The species has become the predominant fish species in many coastal areas and poses strong predatory pressure essentially on epibenthic mollusks. It has also become an important prey species in areas where it is numerous, with signs of individual-level benefits for some piscivorous fish.
