Fish Assemblage Structure

Abstract Invasive Ponto-Caspian gobies (monkey goby Neogobius fluviatilis, round goby Neogobius melanostomus and bighead goby Ponticola kessleri) have recently caused dramatic changes in fish assemblage structure throughout European river systems. This review provides summary of recent research on their dietary habits, age and growth, phylogenetic lineages and gene diversity. The principal food of all three species is invertebrates, and more rarely fish, which depends on the type of habitat, part of the year, as well as the morphological characteristics of species. According to the von Bertalanffy growth model, size at age is specific for the region, but due to its disadvantages it is necessary to test other growth models. Phylogenetic analysis of monkey goby and round goby indicates separation between the Black Sea and the Caspian Sea haplotypes. The greatest genetic diversity is found among populations of the Black Sea, and the lowest among European invaders. The lack of molecular research on bighead goby requires further studies.

Western Basin

Fish assemblage structure has changed dramatically in the Western Basin of Lake Erie since Trautman’s revision of the Fishes of Ohio. Fish surveys near the Bass Islands and adjacent mainland tributaries documented fish faunal distributional patterns during the last three decades. Recent collections (n=1,719 sites) from 1982-2014 indicate that 123 fish species are extant and 27 species have been extirpated from the Bass Islands and nearby tributaries draining the western basin. Extirpation of Polyodon spatula, Alosa sapidissima, Moxostoma lacurum, and Sander glacum occurred; however, A. sapidissima and members of genus Oncorhynchus were introduced and unable to naturalize. Recent collection of A. fulvescens in Schoolhouse bay near Middle Bass Island in May 2012; Umbra limi populations on Middle Bass Island and Kelley’s Island; and Lepisosteus oculatus populations along the southeastern shoreline of North Bass Island are stable in Lake Erie despite increased eutrophication. The current Western Basin fish assemblage includes 107 native, 26 nonindigenous, and 6 alien fish species. Twenty-one native species have been extirpated from Lake Erie, while 6 nonindigenous species have not naturalized and have been extirpated. Six additional species known from within the Lake Erie basin have not been collected from the Western Basin during the study period and current status is unknown. Introduced non-indigenous and alien species are responsible for increased species richness including Neogobius melanostomus, Proterorhinus semilunaris, Salmo trutta, Carassius auratus, Cyprinus carpio, Ctenopharyngodon idella and four records for Hyphthalmichthys molatrix since 1981. Brief comments on distribution, relative abundance, and status are provided for each species.

The Impact

We used an individual-based bioenergetic model to simulate the phosphorus flux of the round goby (Neogobius melanostomus) population in central Lake Erie during 1995–2002. Estimates of round goby diet composition, growth rates, and population abundance were derived from field sampling. As an abundant introduced fish, we predicted that round gobies would influence phosphorus cycling both directly, through excretion, and indirectly, through consumption of dreissenid mussels, whose high mass-specific phosphorus excretion enhances recycling. In 1999, when age-1+ round gobies reached peak abundance near 350 million (2.4 kg·ha–1), annual phosphorus excretion was estimated at 7 t (1.4 × 10–3 mg P·m–2·day–1). From an ecosystem perspective, however, round gobies excreted only 0.4% of the phosphorus needed by the benthic community for primary production. Indirectly, round gobies consumed <0.2% of dreissenid population biomass, indicating that round gobies did not reduce nutrient availability by consuming dreissenids. Compared with previous studies that have revealed introduced species to influence phosphorus cycling, round gobies likely did not attain a sufficiently high biomass density to influence phosphorus cycling in Lake Erie.

Climate warming is expected to alter the distribution, abundance, and impact of non-native species in aquatic ecosystems. In laboratory experiments, we measured the maximum feeding rate and critical thermal maximum (CTmax) of an invasive Eurasian fish, the round goby (Neogobius melanostomus), acclimated to a range of temperatures (18–28°C) reflecting current and projected future thermal conditions for the nearshore Great Lakes. Fish were collected from four distinct populations along a latitudinal gradient from the western basin of Lake Erie to Hamilton Harbour (Lake Ontario) and the upper St. Lawrence River. Thermal tolerance increased with acclimation temperature for populations in lakes Erie and Ontario. However, the St. Lawrence River populations had lower acclimation capacity and exhibited an unexpected decline in CTmax at the highest acclimation temperature. Maximum feeding rates peaked at 18–24°C and declined with temperatures above 24°C. Northern populations in the basin appear poorly adapted to elevated temperatures such that their performance and impact could be reduced by climate warming. Thermal response data from latitudinally distributed populations are needed to inform invasive species risk assessment.

AbstractAge and growth of the invasive population of round goby Neogobius melanostomus from the Slovak stretch of River Danube was examined. The samples (n=1130) were collected soon after the invasion was recorded (2004–2005), and later, when the population was already established (2008–2010). Invasive round goby in newly-occupied areas were found to reach smaller body size (15–153 mm standard length) compared to native populations. Age from 0+ to 4+, determined from scales, was recorded in both sexes. Annulus formed in April–May, which varied with age. Growth of freshly established gobies was negative allometric, suggesting increased allocation of their sources to reproduction, which corresponds to less specialized life-history. However, positive allometric growth found in longer established individuals suggests a shift in allocation towards somatic growth, which corresponds to more specialized life-history typical for native populations. None of the three parameters predicted by the theory of alternative ontogenies and invasive potential met the expectations, though two parameters, i.e. growth rate and age at maturation remain equivocal. This can be explained by too short of a time span that has elapsed from the beginning of invasion, or by ecological disturbances that have broken up otherwise stable environment in the habitat studied.
