Protozoans parasitic on Anguilla anguilla (L.) caught in 5 areas o the Szczecin Lagoon and the River Odra mouth were studied in 1982-1983. A total of 11 protozoan species were found: Ichthyophthirius multifliis, Trichophrya piscium, Trichodina jadranica, Trichodinella epizootica, Myxidium giardi, Spironucleus mobilis, Eimeria anguillae, Zschokkella stettinensis, Sphaerospora gilsoni, Trypanosoma granulosum, and Myxobolus sp. Six species were frequent or very common. The parasitic invasion was relatively strong.
