Keyword(s):
Among the protozoan parasites observed in cyprinid fish from Lake Sasajewun and Lake Opeongo, Algonquin Park, Ontario, were coccidian parasites with oocysts containing eight sporocysts, each of which housed two sporozoites. Three new species of Octosporella Ray and Raghavachari, 1942 are described: Octosporella notropis sp. n. from the intestine, spleen, and swim bladder of the common shiner, Notropis cornutus (Mitchill), and Octosporella opeongoensis sp. n. and Octosporella sasajewunensis sp. n. from the swim bladder of the golden shiner, Notemigonus crysoleucas (Mitchill). The present report represents the first time parasites of this genus have been recorded from fish.
