Science into Practice #121 The effect of handling methods on cortisol levels in harbour porpoises
Nov 15, 2022
There is an increasing concern for improving the well-being of marine mammals held in human care for research, display, and rehabilitation. Therefore, more effort is progressively put into assessing animal stress. The ability to measure stress is indeed necessary for identifying the least stressful methods for capturing and handling marine mammals. Circulating cortisol levels are accepted as a sensitive indicator of acute stress in marine mammals, particularly in relation to capture and handling. This study presents the first long-term monitoring of cortisol levels in four harbour porpoises (an adult male, an adult female and two juvenile females) held in human care.
