“…Both species are bottom dwellers of similar size, habitat use (crevices), and reproductive strategy (Tomlinson and Perrow 2003;Pinchuk et al 2003a) as well as similar dietary preferences, i.e. 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).…”

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.

“…In subsequent years, monkey gobies were recorded at locations downstream of the River Vistula (Fig. 1), in the Włocławski Reservoir at site 38 in 2002 (Kostrzewa, Grabowski 2002, Kakareko et al 2005, and at the river mouth in 2003 (Grabowska et al 2008). The estimated mean rate of this dispersal is 122 km per year.…”

This is the first comprehensive review to examine the role of the central European invasion corridor on fish introductions into Belarusian and Polish inland waters (Dnieper-Bug-Vistula-OderElbe-Spree-Havel). Historical and recent data were assessed, were also found within the corridor -the Amur sleeper Perccottus glenii, gibel carp Carassius gibelio, brown bullhead Ameiurus nebulosus and the topmouth gudgeon Pseudorasbora parva. Their presence is related to numerous accidental introductions to many localities in Belarus and Poland, rather than from using the corridor as an invasion route. One species, the ninespine stickleback, Pungitius pungitius, has migrated from the Baltic basin to the Black Sea drainage systems.

“…We used two predator species: the Ponto-Caspian racer goby Babka gymnotrachelus (Kessler, 1857), sympatric to the selected amphipods, expanding its range in Europe together with them and including them in their diet (Kakareko et al, 2005;Brandner et al, 2013), as well as the red piranha Pygocentrus nattereri, a species with no common evolutionary history with the tested amphipods. Therefore, we could test gammarid responses to familiar predators as well as to those they meet for the first time.…”

Detection of chemical cues of predators and food resources is a key for the behaviour of many species in aquatic ecosystems. We checked whether predator origin and diet, containing potential food and/ or alarm signals, affect the behaviour of omnivorous prey partly sharing their diet with a top predator. We conducted y-maze experiments to study the responses of invasive omnivorous and cannibalistic amphipods (Dikerogammarus villosus and Pontogammarus robustoides) to chemical cues of fish predators, injured amphipods and chironomid larvae (common amphipod food). As the predators, we used the goby Babka gymnotrachelus (sympatric with the amphipods) and piranha Pygocentrus nattereri (allopatric to the amphipods). The fish were either starved or fed amphipods or chironomids. D. villosus preferred predators fed chironomids and conspecifics as well as crushed conspecifics and chironomids, but avoided both hungry predators. Thus, D. villosus may perceive the presence of a top predator as an indication of both food resource and predation risk. P. robustoides avoided predators fed both amphipods (particularly conspecifics) and their alarm substances. The responses of both species depended more on the predator diet than on its species, which is likely to facilitate the recognition of allopatric predators and survival in newly invaded areas.
