Habitats: Caspiobdella fadejewi occurs in large or medium size rivers with slow moving reaches. This species is often found on substratum – in contrast to Piscicola geometra , which is more often collected directly from its fish host. Based upon the distributional records of these two species, the higher number of current records of C. fadejewi than of P. g e o m e t r a probably reflects the differences in collecting methodologies, rather than some other ecological factors.

Status: Prior to this study, Caspiobdella fadejewi was known only from southern Moravia. However, it has been recently recorded at many additional localities in the Labe (Elbe), Odra (Oder), and Morava (March) River basins. The main areas of its distribution in the Czech Republic are associated with the Vltava and Morava River basins. Although it is likely that C. fadejewi has been confused occasionally with P. geometra , an overall trend of rapid spreading of C. fadejewi along the rivers with suitable habitats has been observed during our eleven-year study.
