“…Taking the above into consideration, and the fact that in the brackish waters of the Baltic Sea, both in the Gulf of Gdańsk [SOKOŁOWSKA, FEY 2011] and the Pomeranian Bay (own data), the round goby showed the largest and fastest-growing individuals, it can be concluded that this species found favourable conditions for growth and further expansion in this new area. According to BONISŁAWSKA et al [2014], the percentage of round goby embryos surviving in fresh water is very high (90%), similar to that obtained in salt water, which indicates the possibility of successful reproduction in the presence of other favourable environmental conditions such as a suitable substrate for spawning of this non-native species in the Polish inland waterways. Ongoing research and observations indicate that even in the early ontogenetic stages, round goby is well adapted to very diverse environmental conditions, as evidenced by the high percentage of survival of larvae and the low percentage of losses in rearing fry.…”

“…Laboratory tests conducted by KARSIOTIS et al [2012] showed that the highest round goby growth rates were reached by fish grown in 5-15 ppt salinity, with the highest survival rates observed in water with a salinity of 20 ppt. Euryhaline characteristics of this species, combined with a wide range of thermal tolerance (from -1 to + 30°C) and high fertility [CORKUM et al 1998;MOSKAL'KOVA 1989], allow this invasive fish to colonize new areas, including estuaries.…”

Round goby (Neogobius melanostomus (Pallas, 1814)) is an invasive species in the Oder River. In this study, age of 147 fish was determined using scales and otoliths, and the Fraser-Lee back-calculation method was used for population structure and theoretical length growth rates with 3 mathematical models of growth: von Bertalanffy, Ford-Walford and 2 nd degree polynomial. Fish condition was determined using Fulton, Le Cren and Clark equations. Average total length and weight of fish was 162.00 mm and 83.00 g, respectively. Males were more abundant than females, representing 70% of the fish caught, and achieved greater total lengths and weights. Age 2+ dominated females and 3+ males age groups. Of the three mathematical models used to estimate fish growth, the 2 nd degree polynomial model had the best fit to back-calculated lengths. Males had slightly higher growth rates than females in the first two years of life but comparable in subsequent years. The diet consisted of various benthic organisms that varied with fish age. The most frequently occurring food component was Dreissena polymorpha, which accounted for approximately 70% in the diet of fish with a body length greater than 191 mm.

“…A controlled laboratory experiment has shown that with progressive acclimation, adult round gobies can tolerate a broad range of salinities, although with some variation in physiological performance between individuals at the highest salinities (25 and 30 PSU) (Behrens et al., 2017). Brackish round gobies have also been acclimated to freshwater with subsequent successful spawning as a result (Bonisławska et al., 2014).…”

Non‐native invasive species are a major threat to biodiversity, especially in freshwater ecosystems. Freshwater ecosystems are naturally rather isolated from one another. Nonetheless, invasive species often spread rapidly across water sheds. This spread is to a large extent realized by human activities that provide vectors. For example, recreational boats can carry invasive species propagules as “aquatic hitch‐hikers” within and across water sheds. We used invasive gobies in Switzerland as a case study to test the plausibility that recreational boats can serve as vectors for invasive fish and that fish eggs can serve as propagules. We found that the peak season of boat movements across Switzerland and the goby spawning season overlap temporally. It is thus plausible that goby eggs attached to boats, anchors, or gear may be transported across watersheds. In experimental trials, we found that goby eggs show resistance to physical removal (90 mN attachment strength of individual eggs) and stay attached if exposed to rapid water flow (2.8 m·s−1for 1 h). When exposing the eggs to air, we found that hatching success remained high (>95%) even after eggs had been out of water for up to 24 h. It is thus plausible that eggs survive pick up, within‐water and overland transport by boats. We complemented the experimental plausibility tests with a survey on how decision makers from inside and outside academia rate the feasibility of managing recreational boats as vectors. We found consensus that an installation of a preventive boat vector management is considered an effective and urgent measure. This study advances our understanding of the potential of recreational boats to serve as vectors for invasive vertebrate species and demonstrates that preventive management of recreational boats is considered feasible by relevant decision makers inside and outside academia.
