One of the major rationales for responding to stranded marine mammals, apart from the rescue component, is also the research potential these sorts of events offer. Various biological samples may be collected from live or dead marine mammals that can be utilized to strengthen and optimize the research opportunity on marine mammals in the Philippines. These samples can give us information about, but not limited to, their stranding events, health, life history parameters, population and molecular ecology, histopathology, infectious diseases and chemical contamination which can give us status and clues to many marine environmental changes since these animals are considered as one of the best sentinels for ocean health. However, in the Philippines, practical considerations in collecting blood, tissues and other pertinent samples are complicated by the logistics, and preservation and storage requirements to ensure appropriate studies. Recognizing the limitations in sample collection but still, aiming to improve Philippine marine mammal research, this paper (1) presents marine mammal sampling protocols and strategies suited for the country, and (2) establish these protocols as the standardized method that can be used by first responders, who are mainly members of Philippine Marine Mammal Stranding Network (PMMSN). These standardized methods will ultimately facilitate systematic and long-term monitoring program, provide a competitive edge for the country in producing high quality marine mammal research results. Furthermore, studying these animals will optimize utilization of samples from stranded marine mammals to further enhance knowledge regarding these species. The acquired information will ultimately be used in developing effective conservation measures for these understudied and undervalued animals.
