At 5:15 pm on March 8th, 2013, members of the Pacific Marine Mammal Center (PMMC) Rescue Team responded to a California Sea Lion stranded on Newport Beach. By 600pm, Zc-13-03-08-090 or “Roscoe” arrived at PMMC and was being examined by the staff Veterinarian and Animal Care Staff.He was 38lbs and 42″ long and was suffering from emaciation (underweight) and dehydration. Roscoe started his journey through rehabilitation and was immediately started on tubing’s of clear fluids, then gradually fed a more nutritious fish formula and then taught to eat fish. Soon, Roscoe, the 90th sea lion admitted to PMMC was competing with his pen mates; eating in the big pools and putting on much need weight. After 2.5 months, he was medically cleared, tagged in the front left flipper with Orange Flipper Tag #22464.

With a SPOT5 Satellite Tag provided by WhaleNet and further collaboration with the Riverhead Foundation, we will be able to monitor Roscoe post release.

On May 7th, 2013, Roscoe weighing 83 lbs was release at Crescent Bay, Laguna Beach California. It is hoped, that the satellite tag on Roscoe, one of four satellite tags presently deployed on sea lions by PMMC, will assist scientists in determining the answer to the unusual mortality event that has been ongoing since January 2013.
