Hypertension in Pagothenia borchgrevinki caused by X‐cell disease
Approximately 15% of a population of the cryopelagic nototheniid fish Pagothenia borchgrevinki , found constantly swimming immediately beneath the annual fast ice, in McMudro Sound, Ross Sea, Antarctica, was affected by X‐cell gill disease. This disease affected blood flow through the gill lamellae,...
