“…The few recent studies that have noted benthic fish in the diet have almost all been associated with the recent invasion of round goby (Neogobius melanostomus) in European and North American marine and freshwater ecosystems (e.g. Taraborelli et al, 2010), again suggesting that perch are capable of switching their feeding patterns when an attractive (i.e. abundant, easily caught) new food source becomes available.…”

“…While there have been numerous studies on fish predation by perch (e.g. Horppila et al, 2000;Specziár and Rezsu, 2009;Didenko and Gurbyk, 2016), with observations including cannibalism on perch fry (Lohnisky, 1960;Craig, 2000) and/or predation upon YOY planktivorous cyprinids (Jacobsen et al, 2002;, very few have recorded perch foraging on benthic and/ or shelter dwelling fish species such as gobies (see Almquist et al, 2010;Taraborelli et al, 2010). Further, while the consumption of gobiids by predatory fishes in general has been widely studied in North American waters (e.g.…”

“…The short life-span of P. semilunaris (maximum of two years; Jurajda, unpublished data) and its small size (the vast majority of 1 year fish were smaller than 6 cm·SL −1 ) preclude such major dietary shifts. Indeed, unlike N. melanostomus, for whom molluscs are frequently reported as a dietary item (Ghedotti et al, 1995;Taraborelli et al, 2010), molluscs (mostly D. polymorpha, Bithynia tentaculata, Lymnaea sp. and Pisidium sp.)…”

Key-words:invasive species, Gobiidae, Proterorhinus semilunaris, diet, site-effect, sex-differencesThe tubenose goby, Proterorhinus semilunaris, has expanded its range throughout Europe. Comprehensive studies to identify its impact on native riverine ecosystems, however, are relatively scarce. Here, we evaluate dietary preferences of P. semilunaris on a non-native river to reveal any such impacts. Fish were sampled monthly over 2011-2012 from three sites along the River Dyje (Czech Republic; Danube basin) with differing population levels and food availability. Both the amount of food consumed and dietary composition varied seasonally, with site having a strong effect. Food consumed differed between males and females, but not dietary composition; while diet differed between age classes, but not food consumed. In general, Trichoptera, Chironomidae and zooplankton dominated the diet at all sites, with Trichoptera taken more often earlier in the year and zooplankton later. Mussels were always avoided, despite high abundance, while less preferred prey were occasionally taken in high numbers in response to increased availability or energy demand (e.g. spawning). Fish eggs and fry (all P. semilunaris) were only taken in high numbers at one site, being related to high population level and fry drift from a reservoir. Male feeding declined over the breeding season, presumably due to nest guarding, while female feeding declined over winter, possibly resulting in high mortality. Proterorhinus semilunaris is a feeding opportunist, which may facilitate colonisation in habitats with poor prey availability. No predation pressure on native species was observed through consumption of eggs or fry, though small/young indigenous fish may be affected through diet competition. RÉSUMÉLes gobies demi-lune, non autochtones, Proterorhinus semilunaris, montrent des diffé-rences dans le régime alimentaire liées au site, au sexe et à l'âge. Mots-clés :espèces envahissantes, Gobiidae, Proterorhinus semilunaris Le gobie demi-lune, Proterorhinus semilunaris, a élargi son aire de répartition à travers l'Europe. Cependant, les études approfondies afin d'identifier son impact sur les écosystèmes lotiques indigènes, sont relativement rares. Ici, nous évaluons les préférences alimentaires de P. semilunaris dans une rivière où il n'est pas autochtone pour révéler ces impacts. Les poissons ont été échantillonnés mensuellement sur 2011−2012 à partir de trois sites le long de la rivière Dyje (République tchèque ; bassin du Danube) avec différents niveaux de population et de disponibilité de la nourriture. À la fois la quantité de nourriture consommée et la composition régime alimentaire, effet site, différences sexuelles alimentaire variaient saisonnièrement, le site ayant un effet important. La quantité d'aliments consommés différait entre les sexes, mais pas la composition alimentaire ; le régime alimentaire différait entre les classes d'âge. En général, les trichoptères, les larves de chironomes et le zooplancton ont dominé le régime à tous ...

“…Round goby impacts on yellow perch (P. flavescens) have been extensively studied in the Great Lakes area (9/53; Table S2). Impacts are life stage dependent and include competition for food in the juvenile stages (Duncan et al 2011;Crane et al 2015) or one-sided predation by adult yellow perch on round gobies Lee and Johnson 2005;Truemper and Lauer 2005;Truemper et al 2006;Campbell et al 2009;Reyjol et al 2010;Taraborelli et al 2010;Crane et al 2015). The strengths of both interactions depend on the complexity of habitat structure, biotic factors, and round goby density (Reyjol et al 2010).…”

Invasive species are one of the greatest threats to biodiversity worldwide, and to successfully manage their introductions is a major challenge for society. Knowledge on the impacts of an invasive species is essential for motivating decision makers and optimally allocating management resources. We use a prominent invasive fish species, the round goby (Neogobius melanostomus) to objectively quantify the state of scientific knowledge on its impacts. Focusing on how native fish species are affected by round goby invasions, we analyzed 113 peer-reviewed papers and found that impacts are highly ecosystem and time scale dependent. We discovered round goby impacts to be profound, but surprisingly complex. Even if identical native species were affected, the impacts remained less comparable across ecosystems than expected. Acknowledging the breadth but also limitations in scientific knowledge on round goby impacts would greatly improve scientists' ability to conduct further research and inform management measures.
