Wildlife capture for research, conservation, and management causes significant acute stress. Evidence-based protocols minimize welfare harm during necessary capture events.
Wildlife capture causes genuine acute welfare harm through the fear, physical restraint, and physiological stress of capture events. The welfare justification is usually conservation benefit: the population or individual outcomes achieved through the research or management action justify the individual capture stress. This welfare calculation requires honest assessment: does the data obtained from this capture genuinely justify the welfare cost, or has the value of the data been overestimated relative to the harm? Welfare-positive capture protocols minimize duration, provide appropriate analgesia and monitoring, and follow validated procedures that reduce complications. The welfare cost of poorly conducted captures with preventable deaths through capture myopathy or hyperthermia has no justification.
