“…Researchers have documented that secondary invasions by round goby have been restricted to areas of low species diversity, particularly those lacking a rich benthic fish assemblage (Carman et al 2006). While many lower Great Lakes assemblages are relatively diverse (Poos et al 2009), the section of Mullet Creek that we sampled (200 m upstream of a drowned river mouth) supported a low-diversity assemblage.…”

“…were especially susceptible to competition from round goby due to great overlap in diet and habitat use; at lengths <75 mm, gobies, rainbow darter (E. caeruleum) and logperch (Percina caprodes) consumed common macroinvertebrate resources. During the day, round goby chose prey that are abundant, exposed and active (Carman et al 2006). Similarly, Etheostoma darters are visual, diurnal feeders that forage on a variety of benthic invertebrates.…”

“…young of year and age 1þ individuals seeking uncolonized environments; Cooper et al 2007). The round goby is a successful colonizer, in part, because of its wide tolerance of various environmental factors, high site fidelity on rocky habitats (Ray and Corkum 2001) and opportunistic foraging ability (French and Jude 2001;Phillips et al 2003;Carman et al 2006;Krakowiak and Pennuto 2008).…”

The initial, rapid expansion of the invasive round goby (Neogobius melanostomus) throughout the Great Lakes drainage was largely confined to lentic systems. We recently observed round gobies ascending two tributaries of the St. Lawrence River. The expansion of gobies into small lotic environments may place ecologically similar species at risk. Fantail darter (Etheostoma flabellare) is one of the several benthic species of the New York Great Lakes drainages that are threatened by round goby invasion. We examined the habitat use and diet composition of fantail darters and round gobies in Mullet Creek, a third-order tributary of the St. Lawrence River, NY, USA. The objectives of this study were to determine the degree of habitat and diet overlap between fantail darters and round gobies in a tributary of the St. Lawrence River. Gobies and darters co-occurred at 22% of capture sites. Of the four habitat variables examined (cover, depth, substrate and velocity), only depth use was significantly different with gobies using deeper habitats than darters. Among the two species and size classes sampled (large vs. small), large darters had the most restricted habitat use requirements. There was variation in round goby and darter diet composition, but only moderate diet overlap occurred between fantail darters and round gobies (Cλ ¼ 0.43). Conditions in Mullet Creek were appropriate for the evaluation of possible spatial and dietary competition between round goby and native darters. Early detection and management of round goby invasions is critical to maintaining ecological integrity of lotic ecosystems in the St. Lawrence Valley.

“…Furthermore, in the section of Flint River in Michigan, at which zebra mussels were absent, the diet of round goby changed on a diel basis, with hydropsychid caddisfly and chironomid larvae predominating during the day, chironomid pupae dominating in the evening, and heptageniid mayflies dominating at night (Carman et al, 2006). This suggests not only specialization of bighead goby and round goby to a few prey items, but also an opportunistic behaviour and capacity to adapt to local conditions.…”

Key-words: biological invasions, diet composition, feeding strategy, diet competition, DanubeBighead goby (Neogobius kessleri) and round goby (Neogobius melanostomus) have been invading new non-native areas about two decades successfully. In this study, diet spectrum, seasonal variation, feeding strategy and diet overlap between these two invasive species were assessed. Materials were collected from the Danube at Bratislava by fishing rods and/or electrofishing. The diet spectrum of both species was diverse: a total of 46 food types in bighead goby and 51food types in round goby were observed. Dikerogammarus sp., chironomid larvae and Corophium sp. were the most predominant food types in bighead goby, whereas in round goby, chironomid larvae, Corophium sp., bryozoans and Cladocera predominated. The diet varied over seasons. In the Slovak part of the Danube, bighead goby and round goby have adapted to local food resources, consuming diverse food from small to large items, both with soft and/or hard body. This enhances the capability of these invasive species to spread successfully. It appears that even if both exploit similar food resources, their proportional content differs. Further differences between these gobies were also found in their food behaviour and feeding strategy. Both species tend to be specialists where possible, but round goby demonstrates higher flexibility towards general feeding strategy. RÉSUMÉLes gobies invasifs de Kessler Neogobius kessleri et le gobie à tâches noires N. melanostomus (Teleostei, Gobiidae) sont-ils en compétition pour la nourriture ? le gobie de Kessler et le gobie à tâches noires se sont adaptés à des ressources alimentaires locales, consommant une nourriture variée allant de petites à de grandes proies, à corps mou et/ou dur. Cela augmente la capacité de ces espèces envahissantes à se propager avec succès. Il semble que même si les deux espèces exploitent des ressources alimentaires similaires, leurs proportions diffèrent. D'autres différences entre ces gobies ont également été trouvées dans leur comportement alimentaire et leur stratégie d'alimentation. Les deux espèces ont tendance à être des spécialistes lorsque cela est possible, mais le gobie à tâches noires démontre une plus grande flexibilité allant vers une stratégie alimentaire plus généraliste.

“…There is mounting evidence that round goby predation can affect the size structure and densities of Dreissena populations (Kuhns and Berg 1999;Djuricich and Janssen 2001;Barton et al 2005;Lederer et al 2006Lederer et al , 2008. Nevertheless, the importance of Dreissena in the diets of round gobies can vary among habitats (e.g., shallower vs. deeper offshore areas) as well as over time (Schaeffer et al 2005) and the round goby has invaded areas that lack Dreissena (Carman et al 2006). Thus, the ecological importance of predator-prey interactions between round goby and Dreissena may vary spatially across the aquatic landscape.…”

Predator-prey interactions between round goby (Neogobius melanostomus) and Dreissena are an important component of the food web in their invaded range in North America and Europe. We conducted two experiments to test the effect of round goby predation on Dreissena in coastal lakes connected to eastern Lake Michigan, USA. First, we conducted a density gradient experiment using 1-m 2 cages stocked with 0 to 15 large round gobies (individuals 4 7.5 cm total length (TL)). Presence of large round gobies significantly reduced Dreissena densities in all cages. Second, we conducted an exclosure experiment (treatments: none, 6-mm, and 24-mm mesh) in four coastal lakes in littoral habitats. Excluding large round gobies did not significantly affect Dreissena densities in any of the lakes, although we did find a significant effect of excluding large-bodied (i.e., animals larger than adult round goby that cannot pass through 24-mm mesh) predators in one lake. In combination, our two experiments showed that the strength of predator-prey interactions between round goby and Dreissena can vary with location and/or conditions. We hypothesize that the strength of predator-prey interactions between round goby and Dreissena vary spatially across the aquatic landscape depending on habitat (e.g., rocky vs. sandy substrates), which is critical for understanding foodweb dynamics, especially in areas where the round goby and Dreissena are invasive.
