Abstract

The information provided in this short review covers data about fish parasitological investigation from 1949 till 2023 in Latvia. In total, 42 freshwater fish species were studied and data about 26 species of nematodes was reported. In addition, nematodes of the Eustrongyloides, Goezia, Desmidocercellagenus and Raphidascaris gracillima, Skrjabillanus tincae, Philometra obturans, Philometroides sanguinea species were reported rarely in Latvian waterbodies. Important to note that there are nematodes, Schulmanela petruschewskii, Camallanus (Camallanus) lacustris which prevalence can reach 100%. The parasite Raphidascaris acus is widely distributed and was reported in 28 freshwater species. Distribution of nematodes depends on intermediate hosts such as Oligohetas, Ephemeroptera andCyclopidae and most of them are widely distributed across the country.

Keywords: freshwater fish nematodes, Latvia, Raphidascaris acus, historic data
