“Impacts of Oyster Aquaculture on Subaqueous Soils and Infauna” with Chelsea Duball.

Oysters are praised as ecosystem engineers, not only for their filter feeding, which draws particulate matter and nutrients out of the water, but also for their ability to create natural structures in the wild that can protect against storm surges on the coasts. But, as they expel excess nutrients that they don’t use, is there a potential for an environmental tradeoff, either in soil health or on the other creatures that live within these ecosystems? Chelsea Duball and her team studied oysters in Rhode Island lagoons, researching how much feces oysters could produce at various stocking densities, the short term effects of those feces on soil health, and the long term effects those deposits could have on the tiny creatures that live within oyster farm soils.

Tune in to learn:

  • How to collect oyster feces underwater
  • What kind of underwater critters oyster farming can attract
  • What ecological benefits oysters can provide
  • How oyster farming can impact soils both in the short and long term
