Stress is considered as a characteristic inherent to living organisms when they encounter external stimuli. The physiological responses of fish and crustaceans to various types of stressors are vital to the survival of individuals and the reproduction of populations. A moderate stress state can produce a positive effect (eustress), while a more severe state causes adaptive responses, but it can result in adverse consequences (distress). Generally speaking, the stress response is regulated by two hormonal systems: cortisol hormones and catecholamines. Long-term repeated stress or being in a state of stress for a long time will have a negative impact on other necessary vital functions, including: behavior, growth, development, reproduction, disease resistance, etc.
Under stress conditions, the behavioral responses and physiological processes exhibited by fish (or crustacean) have surpassed the research scope of traditional experimental biology and physiology in aquatic animals. It is of significance to clarify the impact of stress on individuals and populations of fish and crustaceans.
The aim of this topic is to provide up-to-date information on the physiology of stress in fish and in crustaceans. Areas that will be covered under this topic include (1) Endocrinology of the Stress Response; (2) Molecular Mechanism of the Stress Response; (3) Stress and Growth; (4) Stress and Disease Resistance; (5) Stress and Behavior; (6) Nutritional Factors Affecting Stress Responses.
