Abstract
Summary
• Twenty-six species of parasites were recovered from nine species of fish
hosts.
• To date none ofthe fish parasites identified as potential pathogens to Lake
Winnipeg fish by Williamson et al (2005) have been found in the Red River
delta fish samples.
• Two new parasites species know to be pathogenic in fish were discovered in
the samples i e. Bothriocephalus acheilognathi and Sanginicola occidentalis.
• The time of invasion by these two parasite species into The Hudson Bay
drainage is unknown
• Bothriocephalus acheilognathi was widely distributed being present in six
species of fish and found in the south and north basins of Lake Winnipeg.
• Bothriocephalus acheilognathi most frequently infected (prevalence of 74%)
the cyprinid fish host, Notropis atherinoides (Emerald shiner).
• Bothriocephalus acheilognathi was found exclusively in young of the year
emerald shiners.
• Bothriocephalus acheilognathi was recovered from the intestine of older and
and larger pike (Esox lucius), walleye (Sander vitreum), sauger (!>ander
canadensis) white bass (Merone chrysops), goldeye (Hiodon alosoides).
• The Myxozoan occurred on the gills of emerald shiner, occasionally causing
severe pathology.
