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

  1. Determine the fate of particles in raceways, including transport and breakdown
  2. Investigate the rate of excretion of dissolved P from fish and the rate of release from fecal particles in raceways
  3. Design and evaluate scrap iron granule reactors for removing dissolved P
  4. Improve fecal pellet stability and minimize P loss through feed manipulation
  5. Develop best management practices featuring excretion reduction and efficient removal of both particulate and dissolved P
  6. Evaluate the best management practices in commercial settings
