Failing Hearts: What Does Heart Failure in a Fish Look Like?

Professor Ed Mager (University of Miami) examines larval mahi-mahi to determine oil toxicity in their hearts. The cardiac health of the mahi-mahi impacts its form, function, survival ability, and whether the population can fully recover in the Gulf of Mexico post-Deepwater Horizon Oil Spill.

GulfCast: Scott Rikard: Oysters in the Gulf

Scott Rikard manages the hatchery at Auburn University’s Shellfish Laboratory, which produces millions of oysters every year. Scott and his team cultivate oysters for a variety of purposes — some for research and others for aquaculture farms and wild reefs in the Gulf of Mexico.

Their research examines the effects of freshwater releases on oyster populations. The ultimate goal is to help the ecosystem recover, which in turn assists the seafood industry.

Using Amino Acids to Demystify Salt Marsh Food Webs

Salt marshes support commercially and culturally important species and are often subject to natural and human-caused stressors. Gaps in our knowledge of salt marsh food webs make management and restoration decisions difficult after the Deepwater Horizon Spill.

Jessica Johnson helps fill this gap using novel chemical analysis techniques to describe the diets of salt marsh organisms and trace how energy flows through the marsh ecosystem food web. Her work may help inform decision-making if a future spill occurs.
