The state of health of the river lamprey Lampetra fluviatilis (L.) from Lake Dabie compared to the pathogens hitherto found in this host.

The objective of the study was to check the health status of the anadromic river lamprey Lampetra fluviatilis (L.), the most frequently recorded lamprey species in Poland caught in Lake Dabie, connected with the Odra river estuary. The species composition of parasitofauna of the river lamprey from the Polish waters was compared to the pathogens of this host noted so far.
