Relationship Between Temperature and Ceratomyxa shasta–Induced Mortality In Klamath River Salmonids

Creator:

Ray, R. Adam, Holt, Richard A., and Bartholomew, Jerri L.

Abstract:

Water temperature influences almost every biological and physiological process of salmon, including disease resistance. In the Klamath River (California), current thermal conditions are considered sub-optimal for juvenile salmon. In addition to borderline temperatures, these fish must contend with the myxozoan parasite Ceratomyxa shasta, a significant cause of juvenile salmonid mortality...

Estimation of transmission dynamics of the Ceratomyxa shasta actinospore to the salmonid host

Creator:

Ray, R. A. and Bartholomew, J. L.

Abstract:

Transmission dynamics of the actinospore stage of Ceratomyxa shasta to the salmonid host were investigated under field and laboratory conditions. The number of parasites transmitted and the transmission rate were compared between 2 different exposure durations and also among different water velocities, by means of field exposures. Under laboratory conditions,...
