Since June 2013, millions of sea stars along the West Coast have disintegrated and died. Scientists have relentlessly tried to identify the cause of the “sea star wasting syndrome.” (See map of locations with outbreak.)
Typically, the first signs of an afflicted sea star are white lesions appearing on its body. Shortly thereafter, sea stars lose their limbs and their internal organs disintegrate. Although sea stars have the ability to regenerate limbs, the disease often progresses too quickly for them to recover. The exact cause of this disease is unknown. Scientists believe that sea star wasting syndrome may be due to a viral or bacterial infection, and could be exacerbated by increased water temperature. Populations of the ochre and sunflower sea stars, two common West Coast species, have been hit especially hard. Similar die-offs have occurred in the past, but never at the magnitude we see today, and over such a wide geographic area.

In Ocean Conservancy and Pew Charitable Trusts’ recent report “The Law That’s Saving American Fisheries”, we make three key recommendations about how to improve the already vital law that governs our nation’s fisheries:
- Minimize the habitat damage and bycatch of indiscriminate fishing.
- Ensure that adequate forage fish are in the water to feed the larger ecosystem
- Promote ecosystem-based fisheries management
That’s why we were so excited when the Pacific Fisheries Management Council (Council) recently reached a long-awaited milestone in transitioning toward an ecosystem-based approach to managing seafood harvest. The Council’s adoption of a Fisheries Ecosystem Plan (FEP) establishes not only a comprehensive foundation for considering the condition of the California Current Ecosystem in harvest planning and management, but sets a leading example for modernizing fisheries management across the globe.
