Both species suffered hyperglycemia, hypocholesterolemia, increased blood hemoglobin, and decreased blood sugar regulatory precision, but the steelhead recovered more quickly. Acid&ndash;base equilibrium was essentially unaffected, and only the coho suffered any significant interrenal vitamin C depletion.
