Blooms of Alexandrium monilatum, a harmful algal bloom species in the Chesapeake Bay, have increased in both density and distribution since its first observation in 2007. While little is known about this species, A. monilatum releases a toxin that is thought to be harmful to aquatic life and possibly to human health. Sarah Pease of Virginia Institute of Marine Science hopes to shed more definitive light on this possibility by investigating the impact of A. monilatum toxin on oyster health. She will also study the potential for this toxin to be passed up the food chain. Findings, which will be shared with Virginia Department of Health, will cultivate relationships between scientists and policymakers and may improve seafood safety policies.
