“…In its native range, round gobies feed on a large number of mollusc species, amongst others, including Cerastoderma glaucum and Abra segmentum (Svetovidov 1964;Kvach and Zamorov 2001;Pinchuk et al 2003;Bogutskaya et al 2004). Similar to our findings, a higher contribution of annelids, including polychaetes, to the diet of larger round gobies has been documented in a brackish water canal and the southeastern Baltic Sea (Skabeikis and Lesutienė 2015;Hempel et al 2019), although other studies found a declining importance of polychaetes with increasing goby size (Skora and Rzeznik 2001). Thus, our results show a certain accordance with other areas inhabited by this species concerning the diet spectrum of different length classes, though regional differences in diet composition exist, which are possibly linked to the prey availability in the respective environments.…”

“…However, round goby predation on eggs might generally be underestimated (Lutz et al 2020). An ontogenetic diet shift has been reported for several water bodies with the dietary proportion of molluscs increasing with body size Brandner et al 2013;Ustups et al 2016;Hempel et al 2019). The size, at which ontogenetic diet shifts of round goby occur, varies with study area, and slight differences in round goby diet concerning specific prey taxa exist, although the overall feeding ecology is rather similar among regions.…”

“…Fish are only consumed by larger individuals, whereas fish eggs and juveniles have a rather low contribution to round goby diet (e.g. Vašek et al 2014;Ustups et al 2016;Wiegleb et al 2018;Hempel et al 2019). However, round goby predation on eggs might generally be underestimated (Lutz et al 2020).…”

“…Contrary to the smaller length classes, large gobies from LC 3 predominantly consumed polychaetes and bivalves (keeping in mind the small sample size and the absence of statistical analysis for LC 3 ), which might confirm an ontogenetic diet shift with increasing molluscivory for our study area. A higher percentage of molluscs, especially bivalves, in the diet of larger round gobies is known from the Ponto-Caspian region (Svetovidov 1964;Pinchuk et al 2003;Bogutskaya et al 2004), as well as from multiple colonized areas, such as the Baltic Sea (Skora and Rzeznik 2001;Karlson et al 2007), the Great Lakes (Johnson et al 2005;Duncan et al 2011) and river or canal systems (Brandner et al 2013;Hempel et al 2019). In the Baltic Sea, mainly Limecola balthica and Mytilus spp.…”

We examined small-scale distribution and feeding ecology of a non-native fish species, round goby (Neogobius melanostomus (Pallas, 1814)), in different habitats of a coastal lagoon situated in the south-western Baltic Sea. First observations of round goby in this lagoon were reported in 2011, 3 years before the current study was conducted, and information on this species’ basic ecology in different habitats is limited. We found that mainly juvenile round gobies are non-randomly distributed between habitats and that abundances potentially correlate positively with vegetation density and thus structural complexity of the environment. Abundances were highest in shallower, more densely vegetated habitats indicating that these areas might act as a refuge for small round gobies by possibly offering decreased predation risk and better feeding resources. Round goby diet composition was distinct for several length classes suggesting an ontogenetic diet shift concerning crustacean prey taxa between small (≤ 50 mm total length, feeding mainly on zooplankton) and medium individuals (51–100 mm, feeding mainly on benthic crustaceans) and another diet shift of increasing molluscivory with increasing body size across all length classes. Differences in round goby diet between habitats within the smallest length class might potentially be related to prey availability in the environment, which would point to an opportunistic feeding strategy. Here, we offer new insights into the basic ecology of round goby in littoral habitats, providing a better understanding of the ecological role of this invasive species in its non-native range, which might help to assess potential consequences for native fauna and ecosystems.

“…Nonetheless, this group of fishes has recently received increased attention, as several species have invaded rivers and lakes in Australia, Europe and North America (Gertzen et al ., 2016; MacInnis & Corkum, 2000). Globally, the main attributes for invasion successes appear to be their tolerance for a wide range of environmental conditions, a broad diet and aggressive behaviour (Charlebois et al ., 2001; Hempel et al ., 2019; Kotta et al ., 2016).…”

The river goby Glossogobius callidus is native to freshwater and estuarine habitats in South Africa. Individuals [21.1-144.4 mm total length (L T)] were sampled from impoundments in the Sundays River Valley, Eastern Cape, from February 2014 to March 2015. The largest female was 137.2 mm L T , and the largest male was 144.4 mm L T. Length-at-50% maturity was 75.2 ± 2.1 mm L T for males and 76.2 ± 2.0 mm L T for females. Absolute fecundity was 1028.2 ± 131.7 oocytes per fish, and relative fecundity was 50.1 ± 18.1 oocytes per gram. The spawning season extended from October to December. Fish were aged using sectioned sagittal otoliths. The growth zone periodicity was validated using edge analysis. Longevity was more than 7 years for females and more than 6 years for males. Length-at-age was similar for the two sexes and was best described using the von Bertalanffy growth model as L t = 74.7(1 − e-1.0(t + 0.1)) mm L T for the entire population. Using the population age structure, the mortality rate was estimated at 1.3 per year.
