摘要: The fight-or-flight response prepares an animal for coping with alarming situations and their potential consequences, which include injury. The possible involvement of innate components of immunity in the response has received little attention. We determined plasma concentrations of stress hormones and lysozyme activity before and after a 10 min handling stressor. Rainbow trout (Oncorhynchus mykiss) were anesthetized in their home tanks, bled, revived, and then stressed by being held in the air in a net for 30 s and placed in a shallow …
