Rescued Sea Lions Released in Venice Marks End of SoCal Toxic Algae Bloom
- On Wednesday, the Marine Mammal Care Center marked the end of a 14-week toxic domoic acid algae bloom along the Southern California coast by returning four sea lion pups that had been cared for back to the waters near Venice Pier.
- This prolonged and severe algae bloom, worsened by climate change and January wildfires, caused widespread marine mammal poisonings and was the longest on record, surpassing the 2023 event.
- The harmful algae bloom caused illness in hundreds of marine mammals and seabirds, including symptoms such as seizures, fatigue, and dehydration, leading the Care Center to treat more than 500 affected animals this year.
- Los Angeles County approved a $100,000 funding motion introduced by Supervisor Lindsey Horvath to support emergency medical care, public education, and prepare for more frequent future events due to climate change.
- Care Center CEO John Warner urged the public to support marine life by volunteering or donating and emphasized urgent, thorough responses are needed to protect public health and coastal ecosystems moving forward.
