Why Aquaculture Research Matters Now More Than Ever
Global demand for seafood continues to rise while wild capture fisheries face mounting pressure. Aquaculture now supplies more than half of the fish consumed worldwide, and the United States is working to expand domestic production in sustainable, environmentally responsible ways. Mississippi leads the nation in catfish aquaculture, with the Delta region serving as the epicenter of warmwater fish farming.
Pond-based systems in this region face constant challenges: fluctuating dissolved oxygen, nutrient cycling, sediment interactions, dissolved organic matter dynamics, and the impacts of weather events on water quality. Effective management requires scientists who understand both the biology of aquatic systems and the chemistry of the water and soils that support healthy fish production.
The PhD position led by Dr. Sankar M. Sasidharan (Assistant Professor of Wildlife, Fisheries and Aquaculture) directly addresses these needs through applied research in water quality monitoring, biogeochemistry, and geospatial environmental data analysis. Work conducted here has the potential to improve farm-level decision-making, reduce environmental footprints, and support the long-term viability of U.S. aquaculture.

The Research You Will Conduct
As a PhD student in this lab, you will generate high-quality environmental monitoring datasets from active aquaculture systems at the Thad Cochran National Warmwater Aquaculture Center and surrounding facilities. Your work will span:
- Field-based water quality assessments — calibrating and deploying probes, conducting routine and event-driven sampling across ponds and watersheds.
- Biogeochemical analysis — total digestion and sequential extraction techniques on soils and sediments, laboratory analysis of nutrients, dissolved organic matter (DOM), and cations.
- Advanced data analysis and modeling — statistical computing in R, Python, and MATLAB, combined with geospatial analysis using ArcGIS Pro or QGIS to map spatial and temporal patterns.
- Scientific communication — preparing technical reports, peer-reviewed manuscripts, research proposals, and presenting findings at national and international conferences.
This is applied, solutions-oriented science. Your results could help farmers optimize pond management, understand how extreme weather affects water chemistry, or develop better tools for monitoring ecosystem health in warmwater aquaculture systems.
