Auburn University Shellfish Lab Research

Growing in the natural environment, we have little control over what conditions oysters are exposed to during grow-out. However, we are working to understand what leads to mortalities so we can better advise mitigation strategies for the industry. This includes substantial research into the potential cause(s) of Sudden Unusual Mortality Syndrome (SUMS).

We are exploring the potential role of microorganisms, including bacteria and viruses, on SUMS events. In particular, we aim to identify biomarkers that can act as early warning signals that these events are coming. With this research, we will also provide insight into whether these events are caused by microbes.

In collaboration with Dr. Anna Linhoss, we are working to understand the impacts of water quality and water movement on SUMS events.

Working collaboratively across the southern United States, we are exploring the occurrence and severity of SUMS. We are also working with Dr. Taryn Garlock to understand the economic impact of these losses on the oyster aquaculture industry.

We have also joined forces with Dr. Lee Smee at the Dauphin Island Sea Lab to understand the impacts of predator cues on oyster physiology, particularly focusing on whether exposing oysters to predators affects their susceptibility to dermo infections.

Oyster farmers raise oysters typically with the intent of customers consuming the oysters raw on the half shell. To ensure that farmers are taking measures to reduce the risk to these consumers, we study how oyster farmers can affect the risks associated with Vibrios and other pathogens. 

There is current regulatory concern over the interaction between seabirds and oyster aquaculture gear. We are active in research projects that test new and existing bird deterrent strategies to help farmers comply with local regulations.
