“…For example human-mediated passive dispersal with ships and barges can be excluded, as there is no such traffic along the upper Dniester and Strwiąż. The supporting role of artificial dam reservoirs in the species upstream expansion, often mentioned in case of the invasive goby species in large rivers of Ponto-Caspian basin (Slynko et al, 2011), can be rejected as racer goby was present in the upper Dniester long before the construction of such reservoirs on this river (Khudyi, 2002). Transport by anglers could be taken into account, however: i) there is no cross-border movement of anglers with live bait between Poland and Ukraine; ii) the results of tests for population differentiation between middle Dniester and Strwiąż do not suggest point-introductions of low number of individuals (possible founder effect).…”

“…The Kama stretch is characterized by colder waters and a shorter vegetation period. The absence of the goby in the Kama stretch according to results of stud ies of the years 2006-2007 favors the importance of the temperature factor in the dispersal of this Ponto Caspian invader (Slyn'ko et al, 2010). Possibly, the independent dispersal of the tubenose goby with drift ing algae is also inhibited by the presence in the Kama stretch of sites with distinctly pronounced elements of river conditions.…”

“…With respect to ichthyofauna, it was shown that heterogeneity becomes a cause of different contributions of isolated parts of the water body to reproduction of the fish stock (Kuznetsov, 1978;Kuznetsov and Galanin, 2000). The late 1980s were marked by an increase in fish invasions in the Volga and Don basins that assumed a pattern of mass explosive expansion espe cially for representatives of the family Gobiidae (Slyn'ko et al, 2010). One should expect that the rate of bioinvasion processes in some areas of the reservoir will be different.…”

101Kuybyshev Reservoir, the largest reconstructed water body of the basin of the Volga and Europe, is characterized by a rather complex morphology and heterogeneity of conditions of different parts. This cir cumstance manifests itself not only under different hydrological conditions of individual areas but also in the specifics of the anthropogenic impact (Kuiby shevskoe vodokhranilishche, 2008). With respect to ichthyofauna, it was shown that heterogeneity becomes a cause of different contributions of isolated parts of the water body to reproduction of the fish stock (Kuznetsov, 1978;Kuznetsov and Galanin, 2000). The late 1980s were marked by an increase in fish invasions in the Volga and Don basins that assumed a pattern of mass explosive expansion espe cially for representatives of the family Gobiidae (Slyn'ko et al., 2010). One should expect that the rate of bioinvasion processes in some areas of the reservoir will be different. The purpose of the paper is, on the basis of long term observations, to generalize the fact of catches of gobies of the genera Neogobius and Prot erorhinus dwelling near the shore of the Volga stretch of the Kuybyshev Reservoir and compare them with available data on other areas of the reservoir. MATERIALS AND METHODSThe material for the work comprised data on regis tration of gobies in the course of annual observations of the state of juvenile fish near the shore, results of control catches with gill nets (mesh of 16-65 mm), and episodic evidence on catches of gobies with hook and line gear for the period of 1993-2009 in the upper part of the Volga stretch of the Kuybyshev Reservoir. Observations of the state of juvenile fish near the shore were performed in July and September using fry drag seine (length of 12 m, mesh in the wings of 5 mm, mesh in the seine bag of 2.5 mm) and gas drag seines (length of 3 m, gas no. 10) at 18 stations of the littoral at two sections: in the lower reaches of Sviyaga Bay and in the Volga Sviyaga area. Besides this, data on other areas of the Kuybyshev Reservoir were used in the paper. For analysis, similar materials obtained in the course of work in different areas of the Kama stretch in the period of 2006-2007 were also used. The numbers of fish were assessed in specimens per one fishing effort. RESULTS AND DISCUSSIONAt the present stage, near the shore of the upper part of the Volga stretch of the Kuybyshev Reservoir, there are two representatives of the genus Neogobius and one of the genus Proterorhinus. Data of observa tions for the period of 1993-1999 reflect a complete absence of gobies in the composition of catches of juveniles in the littoral and gill nets. Round goby Neogobius melanostomus (Pallas, 1814) was the first to be found in this area (Fig. 1). The first three young of the current year gobies were caught in 2000. Near the shore, round goby is common on rocky grounds and also occurs less frequently in other habitats. Since rocky grounds in the littoral of the considered areas are not widespread, the total numbers of this species in rec...

“…Swiftspreading of numerous aquatic organisms beyond the borders of their historical natural habitats was caused by global climatic changes, active human hydro-constructing activities, large-scale resettlement and introduction of animals into new water ecosystems (Copp et al, 2005;Den Hartog et al, 1992;Davis and Shaw, 2001;Paavola et al, 2005;Havel et al, 2005). Furthermore, qualitative and quantitative destabilization of structure in populations of major native fish species created the free ecological niche of zooplanktivors in Dnieper river basin that also promoted the process of penetration and successful naturalization of Ponto-Caspian marine fishfauna (Slynko et al, 2011, Novitskiy, 2013.…”

“…Despite the fact that S. abaster does not make active migrations (Kuiter, 2001), the most probable way of its expansion in new areas is usually caused by unpremeditated invasion during various human economic activity like anthropogenic modifications of habitat and fish stocking (Slynko et al, 2011), transport in ballast waters (Lavoie et al, 1999) and other. Thereby, the chronology of its findings in different water bodies of Ukraine, especially in Dnieper reservoirs, characterized by some unpredictability and incoherence.…”

Length-weight relationships and morphological variability were assessed for black-striped pipefish Sygnathus abaster Risso, 1827 that has successfully spread in freshwater ecosystems of Ponto-Caspian basin. Ninety females and ninety males were analyzed. Their standard length was 10.65±0.9 cm, ranged 6.90-14.10 cm and the wet weight -0.71±0.02 g (0.15 -1.53 g) respectively. The length-weight relationships were significant (P≤ 0.05) for all samples. The R 2 values ranged from 0.869 to 0.949. In terms of growth, males in all observed areas were positively allometric (b > 3), while females showed isometry (b = 3). Poled samples (males + females) were positively allometric. In addition, measurements of thirteen morphometric characters allowed indicating several morphological differences of individuals from several samples. They manifested in body and head proportions, fins position and body heights with P≤0.05. Furthermore, principal components analysis allowed us to differentiatefish from lacustrine and stream habitats into two separate scatters by external morphology that proved the availability of some different ckreods (ontogenetic channels) of black-striped pipefish. One of them was implemented in lotic ecosystems of the lacustrine parts and another in lentic stream parts of Dnieper reservoirs.
