Abstract

Protozoa of the order Myxosporidia are primarily parasites of fishes, and no major group of fishes is entirely free from infection. Apparently most species of Myxosporidia do not produce serious pathological changes. However, some of the most destructive diseases of fish, such as the "wormy" halibut of the Pacific coast of North America; the "boil" disease of barbel in European waters; and the "twist" disease of salmonoid fish, are caused by myxosporidian infection. These infections are often fatal and sometimes occur in epidemic form. The life history of the myxosporidia has been discussed by Kudo (1920, 1939). The present paper is primarily a report of a survey of myxosporidian parasites which occur in the internal organs of fishes of the Okoboji region.
