“…According to Leppäkoski et al (2002), the last two centuries witnessed the presence of about 100 alien species in the Baltic alone. Of these, as many as 20 non-native species were identified in the Odra estuary (Gruszka 1999). Some of these species became dominant (e.g., It seems that the Odra estuary R. harrisii population is slightly larger than that reported earlier, as evidenced by the increasing numbers of the crabs caught by fish traps (Czerniejewski and Rybczyk 2008).…”

The mud crab is the only non-indigenous xanthid encountered in the River Odra estuary. In 2007-2008, the crabs were collected, using fish traps, to determine sex and to follow variations in individual weight and carapace length and width over a year. Sex-dependent differences in the crab morphometry were studied as well. The largest catch was that obtained in September (23.48% of the total number of 264 individuals) and October (31.82%). Male crabs accounted for 56.44% of the total number; males dominated in autumn (September-December) and spring (March, May, June) catches. Males showed significantly wider carapaces (16.81 ±3.98 mm; range: 5.60-22.90 mm) and mean individual weight (2.15 ±0.94 g; range: 0.15-3.93 g) than females (mean carapace width of 15.05 ±3.33 mm; range: 5.30-19.80 mm, and mean individual weight of 1.47 ±0.60 g; range: 0.13-2.56 g). Of the 11 morphometric characters analyzed, expressed in relative values (%), related to the carapace width, males showed significantly larger claw dimensions (CHL 1 , CHW 1 , CHH 1 , CHL 2 , CHW 2 , CHH 2 ) and smaller abdomen widths (AW).

“…Similar patterns of replacing native gammarid assemblages by alien species has been observed also in other Baltic Lagoons and estuaries, e.g. in the Szczecin Lagoon, Dead Vistula (Gruszka 1999;Konopacka 2003;Jazdzewski et al 2004Jazdzewski et al , 2005 and in the Puck Bay (Szaniawska et al 2003;Jazdzewski et al 2005).…”

During the last decades of the twentieth century, the alien gammarid species Gammarus tigrinus, Dikerogammarus haemobaphes, Pontogammarus robustoides and Obesogammarus crassus invaded the lower Vistula River and its deltaic, partly brackish regions. In brackish waters of the Vistula Lagoon the native Atlantic-boreal species Gammarus zaddachi and Gammarus duebeni have been replaced or at least outnumbered by the aliens. As compared to our earlier studies, through the years 1998-2004 we could observe nearly total decline of the native gammarid populations along the coasts of the Lagoon, and overdomination of the North-American G. tigrinus in most places. Possible reasons for the observed phenomena are e.g. increasing pollution and eutrophication of the Lagoon accompanied by competition between the native and the alien species.

“…C. ischnus usually lives in large rivers and prefers deeper sites with hard substrata, especially those covered by zebra mussel shells (Jażdżewski 1980, Van Overdijk et al 2003, Palmer & Ricciardi 2005. On the other hand, P. robustoides tends to be associated with shallow, sandy sites (Gruszka 1999(Gruszka , Żytkowicz et al 2008 or submerged plants (Dedju 1980).…”

“…robustoides is a large species with high fecundity and invasive potential (Bącela & Konopacka 2005). It is tolerant of oxygen deficiency (Arbaciauskas 2002(Arbaciauskas , 2005 and can live on sandy substrata (Gruszka 1999) as well as in stagnant waters (Arbaciauskas 2002, Grabowski & Bącela 2005 that are avoided by other expansive species, e.g. D. villosus (Devin et al 2003).…”
