A total of 38 Coryphaenoides mediterraneus from the Charlie-Gibbs Fracture Zone (CGFZ), a part of the Mid-Atlantic Ridge (MAR), was studied for parasites and feeding ecology. Sixteen different parasite species were found, most of them belonging to the Digenea (6 species) and Nematoda (6). Twelve new host and 11 new locality records were established, and 8 deep-sea generalists and 5 deep-sea specialists were found. Twelve adult and 3 larval parasites occurred, with Allopodocotyle margolisi (Digenea), Tetraphyllidea indet. (Scolex pleuronectis, Cestoda) and Ascarophis longiovata (Nematoda) being the predominant species. These parasites reached a prevalence of 50.0%, 86.8% and 68.4% with an intensity of infection of 1–10, 1–91 and 1–74, respectively. The food consisted of crustaceans and cephalopods; no further prey items such as fish could be identified. Coryphaenoides mediterraneus demonstrates a parasite fauna similar to that of other deep-sea macrourids. No MAR-specific parasite species were found, and the collected helminths are common fish parasites of the North Atlantic deep-sea basin and the adjacent continental shelf regions. Only few larval epipelagic generalists such as ascaridoid nematodes were found, due to the deep origin of the studied fish between 1700–3500 m. The recorded species rich parasite fauna reflects the wide depth range and opportunistic feeding behaviour of C. mediterraneus on benthopelagic food. The recorded parasite species composition around the MAR appears to be similar to other deep-sea locations in the Atlantic Ocean, demonstrating the wide zoogeographical distribution of these deep-sea metazoans. Consequences of the MAR, the CGFZ and the homogeneous deep-sea environmental conditions for the parasite species distribution are discussed.

Data are presented on the parasite fauna of the European eel, Anguilla anguilla (L.) in three coastal lagoons of the Ebro delta (NE Spain). Ten parasite species were found, four protozoans: Eimeria anguillae, Trichodinapediculus, Myxidium giardi and Myxobolus sp.; five helminths: Pseudodactylogyrus anguillae, Deropristis inflata, Bothriocephalus claviceps, Proteocephalus macrocephalus, Anguillicola crassus and one crustacean: Ergasilus gibbus. The highest prevalences were reported for P. anguillae 84.6%, M. giardi 44.4% and A. crassus 30.8%. Helminth communities were dominated by monogenean P. anguillae. These communities were compared with those from other European coastal lagoons.

The parasitic fauna composition of the spring-spawning (SPR) and the summer-spawning (SSS) stocks of the shortfin squid Illex argentinus was studied in San Matías Gulf, Southwest Atlantic. Seven parasite taxa were identified: 3 cestodes (Scolex polymorphic, Scolex pleuronectis and Nybelinia lingualis), and 4 nematodes (Anisakis sp., Hysterothylacium sp., Ascarophis? sp. and Pseudoterranova? sp.). Based on the prevalence (P) and mean intensity (MI) S. polymorphic [cf. Prosobothrium sp.], S. pleuronectis (Onchobothriidae) and Anisakis were the main parasites of both stocks. P and MI of these parasites were higher in SPR than in SSS. Composition, P and MI of the enteric parasitic fauna found in the subpopulations of I. argentinus in the San Matías Gulf were different from those previously reported for the other stocks of the species that occur on the Argentine continental shelf. These results provide a substantial additional evidence for statement that the SPR and SSS stocks of I. argentinus from San Matías Gulf are biotopically isolated from the stocks that inhabit neighbouring areas of the Argentine continental shelf.

Juvenile golden grey mullet, Liza aurata were collected from Sarıkum Lagoon Lake which connected to the Black Sea at Sinop, Turkey and examined for parasitic fauna. A total of 219 fish were investigated throughout a 1-year period. Parasite species recovered were Trichodina lepsii, T. puytoraci, Gyrodactylus sp., Ligophorus cephali, Ligophorus mediterraneus, Solostamenides mugilis, Ascocotyle sp. (metacercaria) and Ergasilus lizae. Overall infection prevalence (%) and mean intensity values were 95.9% and 412.65 ± 85.31 parasites per infected fish, respectively. Infection prevalence and mean intensity values for each parasite species in relation to season and fish size were also determined and discussed. While Ligophorus cephali and L. mediterraneus are new records for Turkish parasite fauna, the juvenile Liza aurata is a new host record for Ligophorus cephali and L. mediterraneus.

During the last century the recorded parasite fauna of Bison bonasus includes 88 species. These are 22 species of protozoa, 4 trematode species, 4 cestode species, 43 nematode species, 7 mites, 4 Ixodidae ticks, 1 Mallophaga species, 1 Anoplura, and 2 Hippoboscidae flies. There are few monoxenous parasites, the majority of parasites are typical for other Bovidae and Cervidae species and many are newly acquired from Cervidae. This is an evident increased trend in the parasite species richness, in both the prevalence and intensity of infections, which is associated with the bison population size, host status (captive breeding or free-ranging) and the possibility of contact with other ruminant species. In light of the changes to parasite species richness during the last decades, special emphasis shall be given to new parasite species reported in European bison, their pathogenicity and potential implications for conservation.
