SAUSALITO (KPIX 5) – Something in the water has made dozens of sea lions sick, leaving experts at the Marine Mammal Center in Sausalito scrambling to help them.
The center has taken in 70 sea lions since the start of July. All have had domoic acid poisoning.READ MORE: Despite Short-Term Drop in Vaccine Supply, State Officials Predict Full Reopening by Summer
The acid is a neurotoxin released by algal blooms and can cause severe or even permanent brain damage.
“It’s hard. It’s really hard to watch these animals suffer, especially if there’s not something we can do to stop these blooms from happening,” said Dr. Cara Field with the Marine Mammal Center.
Only about half the sea lions make it once they’re rescued.
Most of the animals at the Center are from the San Luis Obispo area, but domoic acid levels are rising and creeping further north.READ MORE: San Francisco Nightlife Rebounds as Pandemic Restrictions Ease
“August and September are peak times for us as well,” explained Dr. Field. “We’re hoping, ‘Oh maybe the worst is over.’ But this is just one small part of our area.”
Since sea lions eat many of the same things from the sea we do, they are the sea’s version of a canary in a coal mine.
The state monitors domoic acid levels. So far, no Bay Area fisheries have been shut down, but the numbers are creeping up around Monterey.
With some of the warmest weather yet to some, sea lions and seafood in the Bay Area may soon feel the effects.
“We eat many of the same things the sea lions do, so if they are getting these seizures and these gastro issues, we can as well,” said Dr. Field.MORE NEWS: U.S. Supreme Court Orders California to Lift Pandemic Restrictions on Home Worship
The wet winter didn’t help. The rain washed a lot of nutrients into the ocean, which helped feed the algae that creates the domoic acid.
