All seven of the United States’ abalone species that live on the West Coast are listed as Critically Endangered or Endangered according to the International Union for Conservation of Nature, or IUCN, Red List of Threatened Species. This is the first global Red List assessment of the species. The West Coast listings were based on an abalones assessment led by Laura-Rogers Bennett of the California Department of Fish and Wildlife, or CDFW, and University of California, Davis.
New research documenting the population crash of the iconic sunflower sea star (Pycnopodia helianthoides), and complete absence of population recovery since the 2013 outbreak of the marine wildlife epidemic sea star wasting disease, was published today in the prestigious journal Proceedings of the Royal Society B. The study calls for new strategies for protecting species impacted by increasingly frequent marine epidemics associated with changing ocean conditions.
Once abundant, white abalone were critically overfished in the 1970s. With the remaining wild white abalone so far apart from one another that they were unable to reproduce successfully, experts determined that captive breeding and outplanting were the best ways to save the species. After early breeding efforts were hampered by disease, the program headquarters moved to UC Davis Bodega Marine Laboratory in 2011.
Scientists are celebrating a population boom among endangered white abalone being raised at the UC Davis Bodega Marine Lab as they approach the day they can begin introducing captive-bred sea snails into their natural ocean habitat — perhaps later this year or next.
Millions of Eggs Bring Program 1 Step Closer to Saving Species
The Bodega Marine Laboratory’s white abalone program has millions of new additions following its most successful spawning ever at the University of California, Davis, facility. Three out of nine recently collected wild white abalone spawned last week, as did seven of 12 captive-bred white abalone. One wild female was particularly generous, producing 20.5 million eggs herself.
