title: Physiological responses of experimental fish to stressful conditions.
abstract: Common stress factors in the laboratory aquarium can include extremes of pH, temperature, or other factors, such as the accumulation of intermediates of nitrification. Each aberration from optimal conditions has a direct physiological effect on fish that can cause death in a variety of ways. The stress effect in fish leading to infectious diseases is a common physiological manifestation of some common biochemical change, probably hormonal, which may compromise the immune system and lead to a decreased disease resistance and ultimately death. Minimization of stress by careful attention to basic fish culture practices is perhaps the best way one can ensure successful laboratory experiments.
