Endangered whales in the inland waters of Washington State will now have individual health records, which researchers hope will help them identify threats to the whales’ health.

There are typically 84 whales living in Puget Sound from spring to fall. These were listed as endangered in 2005 and are both genetically and behaviorally different from other killer whales. They use distinct calls to communicate and eat salmons (鲑鱼) rather than other marine mammals. Because of pollution, lack of prey (捕食) and disturbance from boats, their numbers have varied in the past few decades.

The whales are already thoroughly tracked and recorded. Researchers trail them and keep track of their measurements, waste and exhaled (呼出的) breath.

Individual health records, which combine all of the existing research on the whales, will be added to this program. On Tuesday, during a meeting in Seattle more than two dozen wildlife experts discussed how this would be carried out. The records will include data on behavior, reproductive success, skin diseases and more. They will be used to monitor individual health as well as overall trends. “The goal is to really start getting a lot of data and pull them together in a way that permits easier analysis.” Joe Gaydos said. “Finally, the real benefit of any health record is to help make management decisions.”

The records will help identify threats to the whales’ health and provide insight into how to reduce or fix them. “It will be really powerful to rule out things that aren’t important and focus in on what’s really important,” Barre said.

An initial database will be launched this summer using information on sex, age and gender as a starting point. Additional information will be added next year. Some details, such as who will manage the data and who will have access to it, have not yet been worked out.
