“…This ultimately reveals a pronounced seasonal migration between shallow coastal waters and offshore areas, which can be related directly to different thermal conditions between the seasons. This finding mirrors the annual inshore/offshore seasonal migration of round goby documented in some North American lakes (Andres et al 2020, Pennuto et al 2021) and previously suggested in Europe (Sapota and Skora 2005;Christoffersen et al 2019). These migration events have been shown to translocate significant amounts of energy, prey, and nutrients in a range of lake sizes (Johnson et al 2005, Andres et al 2020, Pennuto et al 2021.…”

“…Our results show pronounced seasonal migration of the round goby from the very shallow coastal areas to the deep offshore regions and vice versa, similar to findings in North American freshwater environments (Andres et al 2020, Pennuto et al 2021. Both the spatial distribution (Kotta et al 2016) as well as biomass of the round goby has increased over time in the Baltic Sea (up to 350 individuals/100m 2 ; Sapota and Skora 2004;Puntila et al 2018), which has resulted in increased translocation of organic matter and energy to deeper offshore regions over time.…”

“…Individual catches of round goby were allocated to one of four quarters (Q); Q1 (January-March), Q2 (April-June); Q3 (July-September) or Q4 (October-December). Information on depth and gear type was available for each catch, except for 12 catches (1.1%), where information on bottom depth was extracted from the ETOPO1 Global Relief Model that includes Baltic Sea Bathymetry by using the function ''getNOAA.bathy'' at resolution of 1 min from the R package marmap (Amante and Eakins 2003;R Core Team 2016;Pante et al 2017). Information about the bottom water temperature at the catch locations (i.e.…”

“…Because of large areas colonized and high population sizes achieved, major effects on the native species and communities have been documented in the wake of its invasion (Crane and Einhouse 2015;Karlson et al 2007;Bergstrom and Mesinger 2009;Poos et al 2010;French and Jude 2001). Recent investigations in the Great Lakes and other inland lakes of North America show that in these environments, this species engages in annual nearshore/ offshore migrations, typically of the entire populations, and that this seasonal migration of the round goby displaces a large biomass, with substantial ecological impacts (Andres et al 2020, Pennuto et al 2021. In general, the round goby has a generalist feeding strategy and preys upon a wide range of different pelagic and benthic invertebrates (Skabeikis and Lesutiene 2015;Nurkse et al 2016) and also fish eggs and small fish (Schrandt et al 2016;Wiegleb et al 2019).…”

Seasonal depth distribution and thermal experience of the non-indigenous round goby Neogobius melanostomus in the Baltic Sea: implications to key trophic relations

et al. 2021

Native to the Ponto-Caspian region, the benthic round goby (Neogobius melanostomus) has invaded several European inland waterbodies as well as the North American Great Lakes and the Baltic Sea. The species is capable of reaching very high densities in the invaded ecosystems, with not only evidence for significant food-web effects on the native biota and habitats, but also negative implications to coastal fishers. Although generally considered a coastal species, it has been shown that round goby migrate to deeper areas of the Great Lakes and other inland lakes during the cold season. Such seasonal movements may create new spatio-temporal ecosystem consequences in invaded systems. To seek evidence for seasonal depth distribution in coastal marine habitats, we compiled all available catch data for round goby in the Baltic Sea since its invasion and until 2017. We furthermore related the depths at capture for each season with the ambient thermal environment. The round goby spend autumn and winter at significantly deeper and offshore areas compared to spring and summer months; few fish were captured at depths < 25 m in these colder months. Similarly, in spring and summer, round goby were not captured at depths > 25 m. The thermal conditions at which round goby were caught varied significantly between seasons, being on average 18.3 °C during summer, and dropping to a low 3.8 °C during winter months. Overall, the fish sought the depths within each season with the highest possible temperatures. The spatial distribution of the round goby substantially overlaps with that of its main and preferred prey (mussels) and with that of its competitor for food (flatfish), but only moderately with the coastal predatory fish (perch), indicating thereby very complex trophic interactions associated with this invasion. Further investigations should aim at quantifying the food web consequences and coupling effects between different habitats related to seasonal migrations of the round goby, both in terms of the species as a competitor, predator and prey.

Round Goby (Neogobius melanostomus) impacts on benthic fish communities in two tributaries of the Great Lakes

Numerous fish species in the Laurentian Great Lakes have been negatively impacted by the establishment of the invasive Round Goby (Neogobius melanostomus). However, limited understanding exists as to how Round Goby has impacted small-bodied native benthic fishes after its secondary invasion into tributaries of the Laurentian Great Lakes. To investigate Round Goby impacts on darter species (family Percidae) in tributary ecosystems, catch per unit area (CPUA) of native and non-native fishes from two riverine ecosystems in Southwestern Ontario (Ausable River, Big Otter Creek) were analyzed. Spatial analyses indicated Round Goby CPUA was highest proximate to the Great Lakes, with a sharp decline in CPUA at sites upstream from each lake (Round Goby CPUA approached zero after 18 and 14 km in the Ausable River and Big Otter Creek, respectively). There was some evidence of a negative relationship between the CPUA of Round Goby and several darter species along the tributary gradients, with moderately negative co-occurrence between Round Goby and Rainbow Darter in the Ausable River and Johnny Darter and Percidae species overall in Big Otter Creek. However, overwhelming evidence of negative associations between Round Goby and all darter species was not found. The negative relationship between the CPUA of Round Goby and some darter species was observed over similar time periods since establishment but greater spatial scales than in previous studies, and therefore has important implications for understanding the ecological impacts of Round Goby in tributary ecosystems.
