Ml. Kent et al., REVIEW OF MYXOSPOREA OF IMPORTANCE IN SALMONID FISHERIES AND AQUACULTURE IN BRITISH-COLUMBIA, Folia parasitologica, 41(1), 1994, pp. 27-37
Several myxosporean parasites are of importance in fisheries and aquac
ulture in British Columbia. The PKX organism and Ceratomyxa shasta Nob
le, 1950 cause disease and mortality, Kudoa thyrsites (Gilchrist, 1924
) and Henneguya salminicola Ward, 1919 are of importance because they
infect somatic muscle, cause unsightly cysts and soft flesh, and thus
reduce the market value of the fish. Myxobolus arcticus Pugachev et Kh
okhlov, 1979, an apparently non-pathogenic species, along with H. salm
inicola, is used as a biological tag in fishery management. Myxobolus
arcticus has also been used in our laboratory as a model for the study
of myxosporean life cycles. Other myxosporeans that have been found i
n salmonids in British Columbia include Myxobolus squamalis (Iverson,
1954), Myxobolus insidiosus Wyatt et Pratt, 1963, Myxidium truttae Leg
er, 1930, Myxidium salvelini Shulman et Konovalov, 1966, Chloromyxum s
p., Parvicapsula sp., and Sphaerospora sp.
