“…Indeed, there was no significant difference in N. melanostomus and C. gobio actual predation of Echinogammarus berilloni, although estimated maximum feeding rates from FRs were higher for the invader. N. melanostomus is a voracious predator of both gammarids and isopods (Corkum et al 2004), with this partially borne out in the present study, indicating the suitability of the FR method in predicting the impact of N. melanostomus on naïve native A. (2003) and (Petty and Grossman 2004).…”

“…Then, we repeat this exercise with the highly invasive and ecologically damaging topmouth gudgeon, Pseudorasbora parva, an Asian fish which has also invaded European waters (Britton et al 2010;Gozlan et al 2010), and its native analogue the European bitterling, Rhodeus amarus, towards two prey species, Daphnia magna and Chironomus spp.. We stress that this exercise is to compare and quantify the impacts of the invaders on the broader prey community and it is not intended to examine any interaction, such as competition, among the invader and native fishes (but see Dick et al 2014Dick et al , 2017. Amphipods and isopods were chosen as common prey items of these fish species (see Welton et al 1991;Dubs and Corkum 1996;Corkum et al 2004;Barton et al 2005). Fishes were obtained using electrofishing (Hans Grassl IG600 type, Aquaculture, France), while prey species were collected by kick sampling (E. berilloni) and dip netting (A. aquaticus).…”

Invasive species management requires allocation of limited resources towards the proactive mitigation of those species that could elicit the highest ecological impacts. However, we lack predictive capacity with respect to the identities and degree of ecological impacts of invasive species. Here, we combine the relative per capita effects and relative field abundances of invader as compared to native species into a new metric, ''Relative Impact Potential'' (RIP), and test whether this metric can reliably predict high impact invaders. This metric tests the impact of invaders relative to the baseline impacts of natives on the broader ecological community. We first derived the functional responses (i.e. per capita effects) of two ecologically damaging invasive fish species in Europe, the Ponto-Caspian round goby (Neogobius melanostomus) and Asian topmouth gudgeon (Pseudorasbora parva), and their native trophic analogues, the bullhead (Cottus gobio; also C. bairdi) and bitterling (Rhodeus amarus), towards several prey species. This establishes the existence and relative strengths of the predator-prey relationships. Then, we derived ecologically comparable field abundance estimates of the invader and native fish from surveys and literature. This establishes the multipliers for the above per capita effects. Despite both predators having known 123Biol Invasions (2017) 19:1653-1665 DOI 10.1007/s10530-017-1378 severe detrimental field impacts, their functional responses alone were of modest predictive power in this regard; however, incorporation of their abundances relative to natives into the RIP metric gave high predictive power. We present invader/native RIP biplots that provide an intuitive visualisation of comparisons among the invasive and native species, reflecting the known broad ecological impacts of the invaders. Thus, we provide a mechanistic understanding of invasive species impacts and a predictive tool for use by practitioners, for example, in risk assessments.

“…The Ponto-Caspian gobies are relatively small (up to 15-20 cm total length), bottom-dwelling species that are usually associated with crevice habitats, though some invading populations have been reported to have established in sandy areas (Sapota 2004). These species are territorial and aggressive, with nestguarding males (Smirnov 1986;Charlebois et al 1997;Pinchuk et al 2003a, b), making them potential competitors to native European species of similar environmental biology, such as Gobiidae in brackish waters (Corkum et al 2004) and Cottidae in fresh waters. This is particularly relevant to the European bullhead Cottus gobio, which is listed in Annex II of the European Habitats and Species Directive (92/43/ EEC) because of declines in various parts of its range (e.g.…”

“…soft-bodied (non-mollusc) benthic invertebrates, especially chironomid larvae and amphipods (Welton et al 1991;Grabowska and Grabowski 2005;Kakareko et al 2005). The bullhead is effectively the European equivalent of the North American cottid, the mottled sculpin Cottus bairdi, which in the Great Lakes has been demonstrated to be adversely affected by invading round goby populations (Corkum et al 2004). There similarities makes the two species very likely competitors for space, spawning grounds, feeding areas and food types.…”

Competitive interactions for food resources between invasive racer goby Babka gymnotrachelus and native European bullhead Cottus gobio

Racer goby is one of several PontoCaspian gobiids spreading throughout European rivers and concurrent with recent declines in threatened populations of a native species of similar biology, the European bullhead. Although suggestive of competitive interactions, evidence thereof is scarce, so we examined behavioural interactions between racer goby and bullhead (single specimens of each species together, also pairs of each species) under experimental conditions (shared space with two shelters) to determine whether the invader displaces the native species when food resources are limited. Food (live chironomids) was added to a single feeder at rates below satiation levels twice over 24 h (once in light and once in darkness), with fish behaviour (aggressive interactions: attacks and threatening) and feeding activity (time spent near or inside the feeder) recorded using video cameras and infrared illumination. Racer goby exhibited aggressive behaviour towards bullhead (mean = 2.5 aggressive events h -1 ), but rarely the inverse (threatening only, mean = 0.05 events h -1 ), significantly limiting bullhead foraging time (by 62 %) and being faster to reach food in the feeding time in 76 % of cases. Gobies were more aggressive during daylight (77 % of all aggressive events occurring in light), and both species spent more time on feeding activities in darkness (88 and 66 % of all time spent in the feeder by bullheads and gobies, respectively). However, the adverse impact of goby on bullhead was independent of light conditions. Our results suggest that under natural conditions, racer goby are likely to displace bullhead during feeding, with potential consequences for foraging efficiency.
