Summary of InvasivenessTop of page
D. villosus is a freshwater amphipod originating from the Ponto-Caspian region. Its range expansion began in the late twentieth century and was associated with re-opening of the shipping canal between the Danube River and Main River (Vaate et al., 2002). Large body size, extremely voracious predatory behaviour, high fecundity and wide environmental tolerance make this amphipod a very successful invader of European waters. Invasion of D. villosus often results in significant local reduction or even extinction of native amphipods and other macroinvertebrates on which it preys (reviewed in Haas et al., 2002; Grabowski et al., 2007). D. villosus is included on the list of the 100 most invasive exotic species of Europe (Devin and Beisel, 2009), and has been deemed the worst non-native invader of England and Wales's waterways by the Environment Agency (BBC, 2011b).

Notes on Taxonomy and NomenclatureTop of page
DescriptionTop of page
As with other gammarids, D. villosus has a typical laterally compressed, arched, and semi-transparent body (See Pictures). The maximum reported body length is 30 mm (Nesemann et al., 1995). The species demonstrates conspicuous pigmentation polymorphisms, with striped, spotted and uniform morphs. This polymorphism is not related to the moult cycle or the life cycle, and may rather serve as a mechanism allowing D. villosus to minimize the probability of being detected by predators on different substrata (Müller et al., 2002; Devin et al., 2004). The other prominent morphological features of the species include: large and powerful mandibles making D. villosus an effective predator (Mayer et al., 2008); long densely situated setae on the flagellum but not on other parts of antenna II; dorsal tubercles on urosome segments I and II with 3-5 spines (Eggers and Martens, 2001; See Pictures). Juvenile individuals resemble adults, but are much smaller in size. Their growth undergoes a number of moultings. Detailed descriptions of D. villosus morphology can be found in Carausu (1943), Eggers and Martens (2001) and Konopacka (2004).
DistributionTop of page
D. villosus is a recent invader of Central and Western Europe freshwater ecosystems. The amphipod is native to the lower reaches of the rivers discharging into the Black Sea and Caspian Sea (Dedju, 1967; Nesemann et al., 1995; Vaate et al., 2002). Between 1920 and 1980, D. villosus invaded the entire lower and middle sections of the Danube River and in 1994 it was recorded in the lower Rhine River in the Netherlands for the first time (Vaate and Klink, 1995). Further spread of the species occurred through the southern migration corridor, including the Danube River (Black Sea basin) and the Rhine River (North Sea basin) hydrologically connected through the Main-Danube canal (Vaate et al., 2002). D. villosus has now been documented in all major rivers of Western Europe (reviewed in Nesemann et al., 1995; Vaate et al., 2002; Jazdzewski and Konopacka, 2002; Bollache et al., 2004). In 2003, this amphipod was found in the Bug River in Poland (Konopacka, 2004), indicating its migration through the central European invasion corridor (Dnieper > Vistula > Oder > Elbe > Rhine). Currently, D. villosus continues its rapid spread throughout Europe and is considered as one of the most probable future amphipod invaders of the North American waters (Ricciardi and Rasmussen, 1998).

History of Introduction and SpreadTop of page
D. villosus is native to the lower reaches of the rivers discharging into the Black Sea and Caspian Sea (Dedju, 1967; Nesemann et al., 1995; Vaate et al., 2002). Its spread to Central and Western Europe initially occurred by active migration and transportation with boats and ships via the southern invasion corridor, which includes the Danube River (Black Sea Basin) and the Rhine River (North Sea Basin) connected through the Main-Danube Canal (Vaate et al., 2002). The first records of the species from the middle Danube in Hungary are dated 1920s to 1930s (Nesemann et al., 1995). In 1989, the species was recorded in the Austrian part of the Danube River, and three years later – in Germany near Straubing and Regensburg (Nesemann et al., 1995). By 1994, following the opening of the Main-Danube Canal, D. villosus invaded the rivers Main and Rhine (Vaate and Klink, 1995). The amphipod then very rapidly spread westwards colonizing the French rivers Moselle (1996), Saône (1997), Rhône (1998), Meuse (1998), Seine (2000), and eastwards through the Mittelland Canal to colonize the German rivers Weser (1998), Elbe (1999) and Oder (2000) (reviewed in Devin et al., 2001; Vaate et al., 2002; Jazdzewski and Konopacka, 2002; Bollache et al., 2004). By 2002, D. villosus had, through the River Oder, reached the brackish Szczecin Lagoon of the Baltic Sea in Poland (Gruszka and Wozniczka, 2008). In the early 2000s, D. villosus was found in a number of European lakes, including Lake Constance (2002), Germany (Mayer et al., 2007); Lake Geneva (2002), Lake Bienne (2005), Lake Zurich (2006), Switzerland (Lods-Crozet and Reymond, 2006); Lake Garda (2003), Italy (Casellato et al., 2006), and Lac du Bourget (2007), France (Grabowski et al., 2007).
In 2003, D. villosus was also recorded in the Bug River in Poland (Konopacka, 2004), indicating on its migration through the central European invasion corridor (Dnieper > Vistula > Oder > Elbe > Rhine). This is proved by the recent (2006) collections of the amphipod in the Belarusian section of the Dnieper River (Mastitsky and Makarevich, 2007).
New records of D. villosus in continental Europe regularly occur. The species has now been found in the UK (BBC, 2010; 2011a, b) and is also expected to arrive soon in North America (Ricciardi and Rasmussen, 1998).
IntroductionsTop of page
Risk of IntroductionTop of page
The spread of D. villosus across Europe has been facilitated by the construction of interbasin canals, in particular the Main-Danube Canal (Vaate et al., 2002) and the Dnieper-Bug Canal (Grabowski et al., 2007; Mastitsky and Makarevich, 2007). The most common mechanisms of dispersal include the active migration and transportation of the species along with boats and ships (Dick, 2009). Using these pathways, D. villosus will likely become widely distributed in continental Europe. In addition, due to its broad tolerance to salinity and temperature, D. villosus may survive in ballast waters of cargo ships and thus become globally dispersed in temperate areas (Bruijs et al., 2001). The examples of the most likely regions to be invaded by D. villosus in the near future include the Great Britain (Dick, 2009) and North America (Ricciardi and Rasmussen, 1998).

Biology and EcologyTop of page
The population genetics of D. villosus has been examined in several studies. Müller et al. (2002) analysed two mitochondrial fragments (16S and COI) in individuals collected widely in Central Europe, including the native range of the species in the lower Danube River. Both markers revealed similar low numbers of unique haplotypes in D. villosus (9 for the 322 bp fragment of the 16S gene and 6 for the 338 bp fragment of the COI gene). The authors also found that the conspicuous colour variation typical for D. villosus does not differentiate at the allozyme level, indicating on panmixia among colour morphs and thus conspecificity.
Wattier et al. (2006) developed three D. villosus-specific polymorphic microsatellite markers (DikF, DikQ and DikS, GeneBank numbers BV678051 to BV678053). Using these novel markers and the COI gene for samples from the whole geographic range of D. villosus in Central and Western Europe, Wattier et al. (2007) found no evidence of genetic bottlenecks during the invasion of the species.
Physiology and Phenology
- rather high plasticity in relation to temperature and salinity (Bruijs et al., 2001)
- remarkable polymorphism of the body pigmentation, which has been repeatedly reported both from the native and invaded ranges (Müller et al., 2002; Devin et al., 2004a)
- high growth rate (Devin et al., 2004b)
- large body size (up to 30 mm in the native area (Nesemann et al., 1995))
- short generation time (Devin et al., 2004b)
- multivotine reproduction cycle, with up to three generations per year (Devin et al. 2004b).

Notes on Natural EnemiesTop of page
Being a large-bodied and numerous invertebrate species, D. villosus is readily consumed by fish. In the introduced range, D. villosus has been field-documented as a food item of the European eel Anguilla anguilla, Eurasian perch Perca fluviatilis, and burbot Lota lota (Eckmann et al., 2008).
Studies on parasites of D. villosus are very scarce. In its native range, this amphipod has been reported to host two microsporidian species (Ovcharenko and Wita, 1996; Wattier et al., 2007), three trematode species (Chernogorenko et al., 1978; Sudarikov et al., 2000), and an epibiont ciliate (Fernandez-Leborans, 2001). In its introduced range, D. villosus has been documented to host only microsporidian parasites (Wattier et al., 2007). There is no published information on the role parasites play in the population dynamics of D. villosus.
Means of Movement and DispersalTop of page
Natural dispersal of D. villosus occurs by active migration (Nesemann et al., 1995; Vaate et al., 2002; Jazdzewski and Konopacka, 2002; Josens et al., 2005). The speed of active D. villosus upstream range extension may reach up to 40 km/year, or approximately 100 m/day (Josens et al., 2005).
Vector Transmission (Biotic)
Biotic vectors of D. villosus transmission have not been documented.
Intentional introductions of D. villosus, though possible, have not been reported.

Impact SummaryTop of page
Environmental ImpactTop of page
D. villosus has been nicknamed the “killer shrimp” for its extremely aggressive behaviour towards native invertebrate species. Due to its large body size and well developed mouthparts, D. villosus is an effective predator, which kills or simply bites off much more prey than it can consume (Dick et al., 2002). In all the European aquatic systems where it has become established, D. villosus has largely replaced both indigenous and exotic amphipod species (Kelleher et al., 1999; Dick and Platvoet, 2000; Whitfield, 2000; Dick et al., 2002; Kley and Maier, 2003; Bollache et al., 2004; MacNeil and Platvoet, 2005; Lods-Crozet and Reymond, 2006). In addition, it readily consumes fish eggs (Casselato et al., 2007) and even attacks fish larvae (Schmidt and Josens, 2004). Due to its predatory activities, D. villosus significantly changes natural food webs of invaded ecosystems and occupies high trophic levels comparable to fish (Van Riel et al., 2006). However, D. villosus is also an omnivorous species able to act as an effective filter-feeder on microalgae (Platvoet et al., 2006).

UsesTop of page
D. villosus does not have any economic value or provide any social benefit. It is not used in environmental services.
DiagnosisTop of page
A description of the specific genetic markers for the identification of D. villosus can be found in the work by Wattier et al. (2006).
Detection and InspectionTop of page
Adult D. villosus can relatively easily be identified in the field using the descriptions provided by Carausu (1943), Eggers and Martens (2001), Konopacka (2004) and Dobson (2012). Juveniles are harder to identify as most of the specific morphological features in such individuals are underdeveloped. The amphipods can be collected using standard nets for benthic sampling (e.g., a rectangular dipnet).
Similarities to Other Species/ConditionsTop of page
D. villosus can be confused with the two other congeners currently spreading in Europe, namely Dikerogammarus bispinosus and Dikerogammarus haemobaphes. Moreover, for a long time D. bispinosus has been considered a subspecies of D. villosus (e.g., Dedju 1967). However, besides certain morphological differences, these three species are isolated both genetically and reproductively (Müller et al., 2002). One of the most prominent discriminating morphological features is the structure of the dorsal tubercles on urosome segments I and II. Although both D. villosus and D. bispinosus possess well developed, pointed tubercles, the tubercles in D. bispinosus are armed with two main apical spines each, whereas in D. villosus the number of such spines varies from 3 to 5. In D. haemobaphes the tubercles are not pointed and typically carry two main spines each. In addition, these three species differ in the pattern of setation of antenna II and the gnathopods (Carausu, 1943; Eggers and Martens, 2001; Müller et al., 2002). A UK identification guide to invasive freshwater shrimps and isopods includes species present in the UK and others that are invasive across Europe (Dobson, 2012).
Prevention and ControlTop of page
Due to the variable regulations around (de)registration of pesticides, your national list of registered pesticides or relevant authority should be consulted to determine which products are legally allowed for use in your country when considering chemical control. Pesticides should always be used in a lawful manner, consistent with the product's label.
Early warning systems
A number of open-access Internet databases and thematic web-sites can be used as the early warning systems since they provide maps of the current distribution of D. villosus in Europe, as well as georeferenced information on the recent findings of this amphipod. Examples of such websites include:
· DAISIE Database on Alien Species in Europe (http://europe-aliens.org/)
· Aquatic Invaders of Belarus: Alien Species Database (http://www.aliensinbelarus.com)
· Website of the online journal ‘Aquatic Invasions’ (http://www.aquaticinvasions.net)
There are no ecologically sound measures for eradication of D. villosus at a waterbody-wide scale.
There are no acknowledged methods to control or remove D. villosus.
Integrated Pest Management
No Integrated Pest Management programs for D. villosus have been developed.
Monitoring and Surveillance
There are no specific monitoring programs aimed at early detection and tracking of D. villosus.
Gaps in Knowledge/Research NeedsTop of page
There are several significant gaps and uncertainties in the current knowledge of the biology and ecology of D. villosus, including:
- environmental requirements
- factors controlling the seasonal patterns of reproduction
- natural enemies
- control menthods.
