Development of a Killer Whale Health Database to Assess Individual and Population Health of Southern Resident Killer Whales (Orcinus orca)
Abstract
Health databases are invaluable tools for assessing both individuals and groups, and have contributed to species management changes and in some cases, population growth.1,2 The southern resident killer whale (SRKW) population is an extensively studied, endangered sub-population of fish-eating killer whales in the Northeastern Pacific Ocean. The population was listed as endangered in Canada and the United States in 2001 and 2005, respectively.3 Population numbers have not recovered and continue to decline. Currently there are only 74 SRKWs. Lack of prey, toxins/contaminants, and boat traffic/noise have been cited as key threats and substantial efforts have been made to address these threats.4 UC Davis and the National Marine Mammal Foundation have collaborated to develop a comprehensive killer whale health database. This electronic medical records system permits data to be queried for individuals, within groups, and across populations to track individual animal health, better understand key factors involved in population declines and aid in population recovery. Currently, the health database includes individual identification, health assessment findings, photographs, field observations, biological sampling, contaminants, photogrammetry, sample archive information, and necropsy findings. By partnering with multiple entities in the United States and Canada, the growing database also includes information from other killer whale populations and with continued investment, will serve as a centralized, cloud-based, secure database that promotes collaboration between researchers, veterinarians, government agencies, and non-profit organizations.
