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

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

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

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
