Abstract

Henneguya salminicola was described in 1919 by Dr. H. B. Ward from cysts found in the body musculature of a silver salmon (Oncorhynchus kisutch Walbaum) taken from the Stickeen River in southeastern Alaska. Ward described the cysts as “pyriform, fairly uniform in size, and hard to the touch. . . . The cysts measured 3 to 6 mm in diameter and were found everywhere through the muscle mass.”

Zschokke and Heitz (1914) had previously encountered cysts measuring 3 to 5 mm in a silver salmon during a parasitological survey of salmonid fishes of the Kamchatka peninsula. Myxosporidian spores within the cysts were identified by these workers as those of Henneguya aschokkei Gurley, although they gave no details as to the spores found and it seems quite probable that Kudo (1920) was correct in his assumption that these spores belonged to the same species which was later described by Ward as H. salminicola.
