Abstract
Pathogens and disease are important though frequently unaddressed aspects
in the conservation of endangered species. Disease becomes important when mortality in the
concerned species reaches epidemic proportions. Such is the case in the Hawaiian monk seal
(Monachus schauinslandi) considered the most endangered pinniped in North American
waters.
The Hawaiian Monk Seal Epidemiology Program is the newest addition to the
National Marine Fisheries Service (NMFS) Marine Mammal Research Program (MMRP) Protected Species
Investigations. This program has been developed to take a proactive approach in identifying
health and disease parameters in the population through the collection and analysis of specimens
from healthy, diseased and dead seals to determine causes of mortality. The primary objectives of
the Program are: Centralize and maintain serum bank and biological specimen bank.
1. Develop conceptual model of health and disease.
2. Construct long-range plan for health assessment.
3. Implement action plan for unusual mortality.
The Unusual Mortality Events Plan for the Hawaiian Monk Seal will be
based on the Marine Mammal Health and Stranding Response Act and recommendations provided in the
National Contingency Plan developed for marine mammals. Risk Assessment, an important element in
the Unusual Mortality Events Plan, will characterize high risk disease, infectivity/transmission
of agents, prevalence and incidence, fatality and morbidity, availability of preventive measures,
diagnostic tests, and public health concerns.
