Report of the live large whale stranding response workshop

Abstract

Reasoned triage and management of live large whale stranding events prompted this workshop. Safety is paramount for humans and must be mitigated for them and whales during responses. Clinical assessment is critical, with emaciation and poor prognosis often worsening welfare if released. Accurate length and estimated weight data are essential. Supportive care and treatments depend on understanding the underlying pathophysiology of stranding. Maintaining an airway, monitoring breathing, minimizing stress, protecting eyes, modulating temperature, and preventing sunburn are priorities. Additional strategies can include mild sedation, fluid administration, and flipper excavation to relieve pressure. Tools to indicate post-release survival include photographs, genetic samples, paint sticks, and identification, VHF, or satellite-linked tags. Acceptable rescue techniques included towing offshore with a tackle or lines over or under the body and around the axillae, inflatable lift bags, and trenching. Nets and towing by the flukes are unsuitable. Refloating of stranded large whales can be considered if a clinical examination suggests a favorable prognosis, and a release method could be safely undertaken without undue stress and trauma to the animal. However, in many cases euthanasia is the most humane option if practical, or letting nature take its course if need be.
