Evaluation of phosphorus loading following a manure spill and an in-stream sediment amendment to reduce phosphorus desorption

Principal Investigator: Shalamar Armstrong
Affiliation: Purdue University
Initiation Date: 2009
  • Develop a comprehensive understanding of P and NH4-N partitioning between fluvial sediments and the overlying water column during and following a manure spill
  • Determine the effectiveness of the current manure spill remediation plan to mitigate P desorption from manure exposed ditch sediments
  • Investigate the influence of sediment particle size distribution on the depth of P contamination as a result of a manure spill under base flow conditions
  • Determine adequate application rates of alum and CaCO3 needed to remediate fluvial sediments following a manure spill
  • Evaluate the efficacy of the sediment alum treatments following a manure spill

Utilization of genomic signatures from Hyalella azteca as a way to quickly evaluate toxicity and need of sediment remediation in the Great Lakes basin

Principal Investigator: Marisol Sepulveda
Initiation Date: 2009
  • Use microarrays for the evaluation of gene expression signatures after exposure to different sediment pollutants
  • Examine this gene expression after the amphipod Hyalella azteca was exposed to different pollutants commonly found in sediments across the Great Lakes basin

Energy efficient and sustainable aquaculture water treatment Using microbial fuel cells and membrane-supported biofilms

Principal Investigator: Robert Nerenberg
Affiliation: University of Notre Dame
Initiation Date: 2010
  • Investigate the feasibility of a new treatment process, based on microbial fuel cells and membrane-supported biofilms reactors for removing nitrogen and sulfide in simulated recirculating aquaculture systems wastewater.
  • Determine the nitrogen and sulfide removal efficiencies, and levels of electric power production
  • Test different reactor configurations under variable loading conditions

Assessing consumer preferences and demand for fish: a market analysis of the Midwest aquaculture industry

Principal Investigator: David Ortega
Affiliation: Purdue University
Initiation Date: 2010
  • Identify consumer preferences and demand for fish products
  • Estimate consumers’ willingness-to-pay for important food safety and quality informational attributes embedded in aquaculture products
  • Assess the competitiveness of aquaculture products with regards to food safety versus imported aquaculture products
