Rescuers to Focus on Monitoring Wayward Whales’ Health

RIO VISTA, Calif.-- Scientists leading the effort to rescue two humpback whales that found their way into the Sacramento River Delta on May 13 have scaled back operations following intense herding efforts yesterday. The acoustical and herding techniques did not result in the outcome that the experts had hoped.

“This rescue effort is a fine balance between herding, which can cause stress to the whales, and caring for their injuries, which requires minimizing stress,” said Dr. Frances Gulland, the lead veterinarian. “Therefore, after an intensive day of herding yesterday, we believe the whales need a day without excessive stimuli.”

Monitoring vessels will stay with the whales during the next few days to assess their health and observe their behavior. They will try to get detailed images of the wounds over the next few days also.

Some vessels used for the whale rescue operations will be redeployed to recreational hotspots for public safety purposes over the busy holiday weekend. However, several vessels will continue to enforce the 500-yard safety zone around the whales, and the U.S. Coast Guard will relay messages to the boating public on Channels 16 and 22A.

An email address has been established for the public to provided feedback about the whale rescue efforts at sacramento.whales@noaa.gov. More information can be found at www.incidentnews.gov .
