Parasites of the invasive goby Proterorhinus semilunaris (pisces: Gobiidae) in Rybinsk Reservoir and checklist of the parasites of gobiids (genus Proterorhinus) in Eurasia

详细

The metazoan parasites of the invasive goby species Proterorhinus semilunaris were studied in August 2015. In total, 101 specimens sampled at four sites of Rybinsk Reservoir were analyzed. Six parasite species were found: Unionidae gen. sp., Paracoenogonimus ovatus, Diplostomum sp., Ichthiocotylurus platycephalus, Posthodiplostomum cuticola, and Camallanus lacustris. Trematode metacercariae were the dominant parasites in all the studied samples. The specific parasites, monogenean Gyrodactylus proterorhini and cestode Proteocephalus gobiorum, were not recorded. The study summarizes the published and original data on the parasite faunae of P. semilunaris and P. marmoratus in Eurasia. The parasite fauna of P. marmoratus comprises 40 species (Microspora—1 species, Ciliophora—4, Myxozoa—4, Monogenoidea—1, Cestoda—4, Trematoda—17, Nematoda—4, Acanthocephala—4, Arthropoda—1). The parasite fauna of P. semilunaris has 92 species (Kinetoplastida—1, Sporozoa—2, Microspora—4, Ciliophora—11, Myxozoa—2, Monogenoidea—2, Cestoda—8, Trematoda—35, Nematoda—12, Acanthocephala—5, Annelida—1, Mollusca—4, and Arthropoda—5).
