Chen, Reducing phosphorous discharge from high density, flow-through aquaculture facilities
This project focuses on innovating strategies to minimize the discharge of phosphor (P) species from high-density, flow-through aquaculture facilities. Our efforts are primarily concentrated on comprehending the journey of P and solids, tracing from their inception into the water until their extraction point.
Objectives
- Determine the fate of particles in raceways, including transport and breakdown
- Investigate the rate of excretion of dissolved P from fish and the rate of release from fecal particles in raceways
- Design and evaluate scrap iron granule reactors for removing dissolved P
- Improve fecal pellet stability and minimize P loss through feed manipulation
- Develop best management practices featuring excretion reduction and efficient removal of both particulate and dissolved P
- Evaluate the best management practices in commercial settings
