Project Description

The abundance of oysters, blue crabs, and spotted seatrout is rapidly declining in the Gulf of Mexico. This project will identify temperature, salinity (freshwater), oxygen (hypoxia), and pH (acidity) thresholds for oyster, blue crab, and spotted seatrout populations based on current and future habitat conditions, including climate variability and human-induced stressors. Thresholds will be quantified in mesocosm experiments, from field observations, and with numerical models. By linking multiple data sets of species recruitment, growth, and survival rates with natural and human induced environmental conditions across time, the project team will identify the large scale drivers and stressors of these populations in Mobile Bay, Alabama.
