The aim of the study was to determine the prevalence and intensity of infection of European eel, Anguilla anguilla (L.), with nematode and monogenean gill parasites. Fifty individuals obtained from Vistula Lagoon stocking material were examined in August and October 2006. The prevalence of infection with Pseudodactylogyrus anguillae (Yin et Sproston) in August was 52.4%, and in October 17.2%, while the mean intensity of infection in the same periods was 4.0 and 1.2 individuals, respectively. The prevalence of infection with Anguillicola crassus Kuwahara, Niimi et Itagaki was 4.8 (August) and 20.7% (October), while the mean intensity was 1.0 and 2.5 individuals. Releasing parasite-infected stocking material is harmful from the perspective of fisheries management and simultaneously increases the area of occurrence of the parasites.

Anguillicola crassus is an Asian nematode accidentally introduced to Europe and parasitising the swimbladder of European eels. Planktonic copepods are the major intermediate hosts but the success of this parasites depends on small fishes, acting as paratenic hosts and transmitting the nematode to eels. The role played by cyprinids and percids in the life cycle of A. crassus in the Vistula Lagoon was analysed. A total of 2398 fish specimens (1091 percids and 1307 cyprinids) were examined within December 1994-March 1997. The presence of the nematode was recorded in zander (Sander lucioperca), European perch (Perca fluviatilis), ruffe (Gymnocephalus cernuus), carp bream (Abramis brama), ziege (Pelecus cultratus), and roach (Rutilus rutilus), the ruffe being the most heavily infected fish species. The present findings advance our knowledge on the biology A. crassus and will help to predict its spread to other bodies of water.

An experiment was conducted to test the effect of the infection by the swimbladder nematode Anguillicola crassus on the survival of the European eel Anguilla anguilla when exposed to hypoxic conditions. Forty-four wild caught and naturally infected eels were placed in an aquarium filled with water from the fishing site (Vaccarès Lagoon, French Mediterranean coast). In this confined environment (271), under decreasing oxygen resources, the first eel death occurred after 45 h (O2 = 0.98 mg l−1) and the last one after 96 h (O2 = 0.48 mg l−1). After dissection and parasite examination, analyses revealed significant negative correlations between the time to death and various parameters of parasite pressure (e.g., number of lumen worms, parasite mass, health state of the infected organ). It was shown that the severity of damage to the swimbladder rather than the count of living parasites was the major contributing factor in explaining the variation in time to death. These semi-experimental data demonstrating an increased eel mortality rate under severe oxygen stress are discussed for their relevance under field conditions, especially during hot summer months.
