Sea Lion Intervention

For several months, numerous sea lions have been hauling out at a north Seattle marina. Observers reported some of the California sea lions seemed to be entangled in fishing gear.

Sno-King Marine Mammal Response, the local NOAA stranding network, assembled a team of responders. Since the marina is a busy area next to a public boat launch and city park, Seal Sitters was enlisted to help.

Seal Sitters volunteers Jonel, John M, Victoria, Dana, Robin and Lynn took up positions along the perimeter.  They helped to direct boat traffic, answer questions from the public, and take photos to document the operation.  The spotting scope was particularly helpful, allowing people to see the entangled animals from a safe distance.

“Numerous folks from the public were present and not alarmed. Having crowd control that could educate people was critical for this very public area.”

Meanwhile, rescue teams from WDFW Marine Mammal Investigations, SR3 (stranding network partner of Seal Sitters) and SeaDoc Society boarded 2 boats and carefully approached the dock where the sea lions were gathered.  Two California sea lions were sedated with tranquilizer darts.

The responders were able to free the first sea lion of the fishing rig that had caused a horrific injury. The second sea lion was examined and what looked like an entanglement turned out to be an old scar.  Both animals were given drugs to reverse the sedation, and they quickly recovered.  

This disentanglement action was a perfect example of the cooperation among the Pacific Northwest stranding networks.  Seal Sitters volunteers were pleased to contribute vital public outreach and education to the effort.
