First record of trypanosomes from the blood of sculpins (Cottus ricei and C. cognatus) from Lake Superior, WI, USA

During parasitological research of fishes in Lake Superior (USA) in August-September 1994, infection with trypanosomes of the blood of sculpins (Cottus ricei and C. cognatus) was recorded for the first time. The descriptions of three morphological groups of the genus Trypanosoma: T. sp. I, found in blood of C. ricei, T. sp. II and T. sp. III from blood of C. cognatus, have been provided.

Parasites of the recently established round goby (Negobius melanostomus) and tubenose goby (Proterorhinus marmoratus) (Gobiidae) from the St. Clair River and Lake St. Clair, Michigan, USA

Specimens of the recently established European round goby (Negobius melanostomus Pallas, 1811) and tubenose goby (Proterorhinus marmoratus Pallas, 1811) were collected from different locations in the St. Clair River and Lake St. Clair, USA and were examined for parasites. Parasites were observed in 76% of the round gobies and 35% of the tubenose gobies. Four species of parasites in the gobies occur in the Black Sea watershed. Two of them have been reported in North America for the first time: Sphaeromyxa sevastopoli Naidenova, 1970 and Ichthyocotylurus pileatus (Rudolphi, 1802). Three parasite species found in the gobies are endemic to North America and were most likely obtained locally.
