Thermal Ecology and Stress: A Case History for Red-Sore Disease in Largemouth Bass

Gerald W. Esch and Terry C. Hazen



The stress concept is analyzed and related to individual, population, and ecosystem levels of biological organization.  Red-sore disease, produced by the gram-negative bacterium Aeromonas hydrophila, is discussed in terms of its relationship to stress.  An effort is made to relate seasonal changes in red-sore disease to environmentally induced alterations in the physiology and behavior of largemouth bass.  A hypothesis is proposed to explain these interactions in terms of stress.
