Oysters are an iconic and important part of Louisiana’s coastal ecosystem, culture, and economy. But in addition to harvest pressure, the oysters are under stress from increased freshwater, either from heavy rainfall fueled by climate change or diversions of water from the Mississippi River. In this episode Morgan Kelly, an Associate Professor of Biology at Louisiana State University, discusses the health and prevalence of oysters, how they are stressed by freshwater, and ways to relieve that pressure through management of river diversions, use of hatcheries, and selective breeding.
