From "pike on the" Very cool info here for sure!!! Here is a pic of a pike I caught with black spots the other day.....

The northern pike is host to a vast assemblage of parasites. Toner (1966) in his summary of information on the pike listed almost a full page of published records. Hoffman (1967) listed the following parasites for this species in North America: fungi, Protozoa, Trematoda, Cestoda, Nematoda, Acanthocephala, leeches, Mollusca, and Crustacea. The parasite most often seen and of concern to anglers is the strigeid fluke Uvulifer ambloplitis. The externally encysted stage of this trematode, called black-spot, is often present in extreme numbers on individual pike. This parasite is not transferable to man, is readily killed by adequate cooking or removed by skinning the fish. This species also suffers from a septicaemic "red sore" disease caused by the bacterium Pseudomonas hydrophila, which is also responsible for the condition in frogs known as "red leg." In northern pike it results in ugly red necrotic lesions involving the muscle tissue (Margolis 1951). The pike also are subject to neoplastic tumors that are true cancerous lymphosarcoma. Both render the fish unsightly and can cause concern to those who catch the infected fish. Neither of these "diseases" is known to be transferable by contact to man.
