An account is presented of the incidence of infection of Triaenophorus tricuspidatus (Bloch 1779) in Coregonus and Leucichtys species in Manitoba based upon an examination of 7,000 fishes. The survey covers thirty lakes for the southern Manitoba border to mile 200 on the Churchill Railway, a few lakes in north eastern Saskatchewan, and includes the larger lakes of Winnipeg, Winnipegosis and Manitoba. The morphology and biology of the larvae and adult stages are described; and an incomplete description of the life cycle is given. The possibilities of economic control are discussed.
