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.
Research in the Marine Invertebrate Fisheries and Conservation Lab (resident scientist Laura Rogers-Bennett, Center for Wildlife Health and California Department of Fish and Wildlife) focuses on examining processes which impact marine invertebrate populations and communities then applying these findings to fisheries management and marine conservation issues. Marine invertebrates have become the most important fisheries in California in terms of both volume and value. In 2012, four of the top five fisheries were marine invertebrates.
The Bodega Marine Laboratory non-indigenous/pathogen facility and effluent treatment system was established in 2014 and supports non-indigenous and invasive species research. The facility enables scientists and students the ability to investigate introduced/invasive species as well as pathogens that are the basis for emerging diseases and changing biodiversity.

Marine invasive species are species introduced by human activities to new habitats where the species are not native. Marine invasive species are causing more and more costly economic problems, such as fouling the hulls of boats, which slows the vessels and increases the fuel costs. BML researchers continue to be among the top in the field of marine invasive species.
The Shellfish Health Laboratory (SHL) at BML is the State Department of Fish and Wildlife’s shellfish health facility and is also a UCD Vet Med lab through the Principal Investigator, Colleen Burge. Findings from the SHL have been critical to the State of California and these include:
An important focus for Ted Grosholz involves the ecology and potential for restoration of native Olympia oysters Ostreola conchaphila (previously Ostrea lurida) in western estuaries. Estuaries in California have been heavily impacted by human activities that have resulted in substantial loss of habitat, invasion by non-native species, inputs of sediments and contaminants and other stressors that have resulted in substantial declines in ecosystem function.
