“…As all fish eggs and fry consumed were of P. semilunaris, and no predation on native fish eggs and/or fry was observed, there appears to be no impact on native fish fauna through direct predation. Such opportunistic egg cannibalism (see also Vašek et al, 2014 andAdámek et al, 2010) has also been observed in N. melanostomus under laboratory conditions (Meunier et al, 2009), where it was connected with males abandoning nests. The fact that egg and fry consumption at Nové Mlýny occurs primarily in May tends to confirm that the behaviour is connected primarily with P. semilunaris breeding behaviour and is not a general behaviour pattern.…”

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 ...

“…A number of studies, both on the Dyje and elsewhere, have shown rip-rap to be the preferred habitat of tubenose gobies, with very few fish ever venturing away from the banks (e.g. Vasek et al, 2014). Immediately after being caught, the perch were sacrificed by overdosing with clove oil (∼0.1 ml l À1 ).…”

“…However, in both continents P. semilunaris has not (yet) widely expanded its nonnative range. Thus, in North America this species remains restricted to some lakes (e.g., Lake St. Clair, Lake Erie, Western Lake Superior: Vanderploeg et al, ) without any pronounced impacts except for predation on benthic macroinvertebrate communities through competitive interactions (e.g., Mikl et al, ; Vašek, Všeticková, Roche, & Jurajda, ; Všeticková, Janác, Vašek, Roche, & Jurajda, ). N. fluviatilis has colonized several freshwater ecosystems of Europe (Copp et al, ; Grabowska, Grabowski, & Kostecka, ; Jakovlić et al, ) through invasion pathways overall similar to those of other invasive gobies, namely human‐mediated transportation via tourist boats and angler bait buckets (Grabowska et al, ; Jakovlić et al, ).…”

“…Like many other bio‐ecological features (e.g., Karakuş et al, ; Valová, Konečná, Janác, & Jurajda, ), the feeding ecology of both P. semilunaris and N. fluviatilis has been investigated to some extent in both their native (Adámek, Andreji, & Gallardo, ; Gaygusuz, Gürsoy Gaygusuz, Tarkan, Acıpınar, & Türer, ; Pinchuk, Vasil’eva, Vasil’ev, & Miller, ) and nonnative ranges (Grabowska et al, ; Kakareko et al, ; Kocovsky et al, ; Vanderploeg et al, ; Vašek et al, ; Všeticková et al, ). However, in their native range of Turkey, only one single study per species is available (i.e., Gaygusuz et al, ; Gürsoy Gaygusuz, Tarkan, & Gaygusuz, ), making both the assessment and management of their risks of invasion (i.e., through translocation) poorly informed.…”

The feeding ecology of the two gobiid species monkey goby Neogobius fluviatilis and western tubenose goby Proterorhinus semilunaris was studied in four natural lakes of the Marmara Region (NW Turkey), with special emphasis on seasonal and ontogenetic shifts in diet. Both species had similar food composition consisting of zooplankton and detritus. However, diet composition of both species significantly varied amongst lakes, and particularly so for P. semilunaris with seasonal and ontogenetic differences. Diet composition and seasonal/ontogenetic differences were overall similar to other populations of these gobiid species from both their native and nonnative ranges. The present findings suggest high plasticity in the diet of these two gobies, which can opportunistically utilize available food resources.
