Opis:
Introduction. The european eel is one of the major fishing objects of the Russian fishery zone of the Vistula Lagoon (Baltic Sea). This is the reason that its parasite fauna was studied within 1998-2005. Material and methods. Totally 142 individuals of 35-81 cm in length were examined. The parasites collected from various organs were fixed and processed according to commonly accepted methods. Results. Twenty two parasite species representing the following higher taxa: Coccidia (2), Oligohymenophorea (2), Myxosporea (5), Monogenea (1), Cestoda (2), Trematoda (2), Nematoda (4), Acanthocephala (2), and Crustacea (2) were recovered. The following main features of the eel parasitofauna were determined: high specificity, predominance of the parasites with simple life cycle, the presence of three invader species (Anguillicola crassus, Pseudodactylogyrus anguillae, and Paratenuisentis ambiguus). The latter species was found in the Vistula Lagoon for the first time

Opis:
The morphology, infraciliature, and silverline system of three marine scuticociliates, Uronema marinum Dujardin, 1841, U. heteromarinum nov. spec. and Pleuronema setigerum Calkins, 1902, isolated from coastal waters off Qingdao, China, were investigated using living observation and silver impregnation methods. Due to the great confusion in the species definition of the well-known species U. marinum, we have documented a detailed discussion/comparison and believe that most of the confusion is due to the fact that at least 2 closely-related sibling morphotypes exist which are often not recognized. Based on the data available, U. marinum is strictly defined as follows: marine Uronema ca. 30 × 10 μm in size, with truncated apical frontal plate and smooth pellicle, extrusomes inconspicuous, cytostome located equatorially, 12–14 somatic kineties and one contractile vacuole pore near posterior end of kinety 2. Uronema heteromarinum nov. spec. resembles U. marinum but can be distinguished morphologically by its notched pellicle with conspicuous extrusomes and reticulate ridges, the 15–16 somatic kineties, widely separated membranelle 1 and membranelle 2, as well as the subequatorially positioned cytostome. Based on the Qingdao population, an improved diagnosis for the poorly known Pleuronema setigerum is: marine slender oval-shaped form, in vivo about 40–50 × 15–20 μm; 3–5 preoral kineties and 14–22 somatic kineties; membranelle 1 and 3 three-rowed, and posterior end of M2a ring-like. The small subunit (SSU) rRNA gene for all three organisms were sequenced and analyzed with standard methods.
