Future monitoring may also include genetic sampling to evaluate the population structure of wild populations and additional health monitoring to assess the level of infection with the withering syndrome disease, as well as to provide early detection of other diseases among the wild population. Die-offs associated with the disease are associated with sea surface warming events (e.g., El Niño events, thermal discharges). They might grow up to 4 meters long. Working in partnership with several other organizations, we study the biology, behavior, and ecology of the black abalone.

Our partners at the University of Washington, University of California Santa Cruz, University of California Davis-Bodega Marine Lab, and CDFW have made significant advancements in disease research, including the development of novel methods to detect the withering syndrome pathogen in wild abalone and their habitat, antibiotic treatments for removing the pathogen from captive abalone, correlations between increased water temperature and increased infection and disease rates, and the discovery of a bacteriophage that infects the pathogen and increases the survival of infected abalone. Herrmann commercially forages seaweed to sell to restaurants in places like Napa and San Francisco. As with all foraging, research is key. There are also lesser-known varieties, like sea lettuce, a delicate green seaweed also used in salads. Sea vegetable foraging has become so common, in fact, that you can take a class to learn what to harvest and what to avoid. Feather Boa is a tough and leathery kelp that has pneumatocysts every few inches that float it up to the surface of the water. Occasional floatation bulbs also attached to the stem. Although all wild black abalone are likely infected, full manifestation of the disease appears to be more prevalent in the southern portion of the black abalone range (south of Point Conception, California) where water temperatures are relatively warmer.

Once methods have been developed, we can learn from the white abalone captive propagation and outplanting programs to inform development of such programs for black abalone. These tools include: Investment in disease monitoring, genetic testing and ongoing research on abalone reproduction and recruitment dynamics (e.g., how the distance between individuals affects fertilization success) will be critical to guide enhancement efforts. The disease’s northward progression poses a continuing threat to the remaining healthy populations; however, the impacts may be reduced due to the potential for black abalone to develop genetically-based disease resistance, as well as the existence of a phage that infects the pathogen and improves the survival of abalone.
