“…Local disappearance of G. lacustris and A. aquaticus may be a result of antagonistic relationships (predation and competition) between these species and G. fasciatus (Berezina et al., 2009). Experimental studies by Pankova and Berezina (2007) confirmed that G. fasciatus being an active predator upon A. aquaticus and may have a strong impact on the density of this isopod in natural habitats. The predation of G. fasciatus causes abrupt changes in the taxonomical composition of benthic communities (Berezina, 2007).…”

“…Amphipods significantly contribute to benthic biomass of different aquatic ecosystems and play an important role in their food webs as a trophic link from primary producers to higher‐order consumers, including fish and birds (Pankova and Berezina, 2007). G. fasciatus was introduced into different aquatic ecosystems of the former USSR with the aim of enhancing food base for fish (Berezina, 2007).…”

The objective of the study was to assess the effect of the Baikalian amphipod Gmelinoides fasciatus, a successful invader into Europe, as a fish food source in Lake Peipsi to where it was introduced in the 1970s. In 2002-2006, the littoral macrozoobenthos was studied along 17 transects (0.1-4 m depth, 384 quantitative samples) to determine the recent distribution of G. fasciatus and its share in the benthic community. Earlier records on the littoral macrozoobenthos from the years 1970, 1980, 1990 and 2000 were also used for comparison. Our results indicate that the invasive G. fasciatus is the dominant species (about 43% of total macrozoobenthos abundance) in the littoral zone of Lake Peipsi, while the native gammarids Gammarus lacustris and Pallasea quadrispinosa appear to be extinct and oligochaetes seem to have declined. G. fasciatus preferred hard substrates and it was mainly distributed close to water shallow beach areas (water depth <0.2 m), where its abundance reached locally up to 29 000 ind. m )2 (97% of total macrozoobenthos abundance). This distribution pattern of the invader in summer makes it mostly inaccessible for adult fish and increases its survival rate. Being highly mobile, G. fasciatus is not sensitive to water level fluctuations in shallow lakes. These behavioural characteristic increase its population success.

“…The isopod Asellus aquaticus and another amphipod Pallasea quadrispinosa were also subjected to the competition by the invader, reaching high abundances (above 1000 m −2 and 0.5 g m −2 ) only at sites with low G. fasciatus densities (Berezina et al., 2009). It had been experimentally confirmed that the local disappearance of the native crustaceans G. lacustris and A. aquaticus after the establishment of G. fasciatus may have been a result of interspecific interactions, particularly selective predation by the invader (Pankova and Berezina, 2007; Berezina, 2009).…”

Summary This paper focuses on the role of invasive, omnivorous/carnivorous amphipods in the food web of lakes and evaluates their significance as food items for fishes in two major lakes and reservoirs of the northwestern region of Russia: Lake Ladoga and Rybinsk Reservoir. Fish samples from both water bodies were collected, there age determined and their stomach content analysed to assess the role of the introduced amphipod in the diet. Fish species mainly analysed were: perch Perca fluviatilis, ruffe Gymnocephalus cernuus, burbot Lota lota, roach Rutilus rutilus, vendace Coregonus albula and kilka Clupeonella cultriventris. Analysis of original and literature data showed that the energy flow from zoobenthos to fish was modified by the Baikalian amphipod Gmelinoides fasciatus, introduced in the 1960s–80s into many lakes and reservoirs of Russia. The invader established successfully in different aquatic systems, rapidly reaching high abundances. Examples from Lake Ladoga and the Rybinsk Reservoir confirmed that the species is an important food item for littoral benthivorous fishes (ruffe, perch, gobies, burbot), especially at early ontogenetic stages and also for several pelagic fish (vendace, kilka). Although these fish species are considered low food quality, they enrich the food supply for large predatory fish species. In Lake Ladoga, G. fasciatus influenced negatively the abundance and biomass of native benthic invertebrates (including Gammarus lacustris and Asellus aquaticus) which were previously important prey items for littoral fishes: in the beginning of introduction up to 24100 m−2 and 33.5 g m−2; after introduction 6200–7800 m−2 and 16.5 g m−2, respectively. At the same time, the invader uses food sources (chironomids and oligochaetes) that would otherwise not be available to fishes. Therefore, the introduction of G. fasciatus into lakes and reservoirs of European part of Russia led to a greater share of the benthic productivity available to fishes, thereby allowing the intensive use of new ecosystem components and increasing the overall production in these systems.

“…The most common non-indigenous species in European large lakes are the zebra mussel Dreissena polymorpha Pallas (Ricciardi, 2003) and the Baikalian gammarid Gmelinoides fasciatus (Stebbing) (Timm & Timm, 1993). The latter is the most active invasive species in Eastern Europe (Pankova & Berezina, 2007). G. fasciatus was introduced in the 1960s and 1970s from the Lake Baikal basin into lakes and reservoirs in the former USSR with the purpose of enhancing fish production (Berezina, 2007).…”

Lakes in Europe have a bipolar distribution by latitude with higher lake densities in the north (58-65°N) and south (38-48°N). By area, 95% of the large lakes ([100 km 2 ) are located at altitudes lower than 100 m above sea level (ASL) and only 1% lie higher than 1,000 m ASL. Physically large lakes exhibit several similarities to seas and oceans in their thermal structure and circulation dynamics. From the chemical point of view, lakes are important accumulation sites for substances transported from the watershed or built up in the lake itself but they may contribute positively to global greenhouse gas emission. Fauna and flora of ancient large lakes such as the Caspian Sea and Lake Ohrid include large numbers of endemic species, which become endangered if conditions change because of direct human impact, alien species invasions or climate change. Large lakes offer a wide range of ecosystem services to society, the multiple use of which creates multiple pressures on these water bodies such as nutrient load and toxic pollution, modification of hydrology and shore line structure, and shifting of the food web balance by stocking or harvesting various species. Although large lakes are among the best-studied ecosystems in the world, the application to them of environmental regulations such as the European Water Framework Directive is a challenging task and requires that several natural and management aspects specific to these water bodies are adequately considered.
