> Sea stars, also known as starfish, are marine invertebrates that play a vital role in maintaining the health of ocean ecosystems. They are voracious predators that feed on a variety of invertebrates, including sea urchins, mussels, and barnacles. By keeping these populations in check, sea stars help to maintain the biodiversity of their habitats.
> In 2013, a disease known as sea star wasting syndrome (SSWS) began to spread rapidly along the Pacific coast of North America. The disease quickly decimated sea star populations, with some species experiencing declines of up to 90%. The cause of SSWS is still unknown, but it is believed to be caused by a virus or bacteria.
> The loss of sea stars has had a ripple effect on ocean ecosystems. With fewer sea stars to control their populations, sea urchins and other invertebrates have proliferated, leading to declines in kelp forests and other important habitats.
> Efforts are underway to restore sea star populations. Scientists are conducting research to better understand the cause of SSWS and are developing methods to protect sea stars from the disease. In addition, some communities are working to reintroduce sea stars to areas where they have been wiped out.
> It is still too early to say whether sea star populations will fully recover from the devastation caused by SSWS. However, the efforts that are being made to protect and restore sea stars give hope that these important creatures will once again thrive in the Pacific Ocean.
Here are some specific examples of how sea stars are being restored in California:
>* In 2017, the California Department of Fish and Wildlife (CDFW) launched a sea star restoration project in Morro Bay. The project involves collecting sea star larvae from healthy populations and raising them in a controlled environment until they are large enough to be released into the wild. So far, the project has released over 50,000 sea stars into Morro Bay.
>* The University of California, Santa Cruz (UCSC) is also conducting sea star restoration research. Scientists at UCSC are studying the genetic diversity of sea stars and developing methods to breed sea stars in captivity.
>* The Aquarium of the Bay in San Francisco is home to a sea star nursery. The nursery is part of a collaboration between the aquarium and CDFW to restore sea star populations in the San Francisco Bay Area.
>* In addition to these projects, there are a number of community-based efforts to restore sea stars. These efforts include volunteer beach cleanups, where volunteers collect sea stars that have washed up on shore and return them to the ocean.
> The recovery of sea star populations is a long-term process, but the efforts that are being made give hope that these important creatures will once again thrive in the Pacific Ocean.
