Marine aquaponics for the Great Lakes region

Principal Investigator: Paul Brown
Affiliation: Purdue University
Initiation Date: 2022

Aquaponics food production systems produce more food on less land, using less water than conventional food production systems. Further, they can be located near population centers, diminishing the carbon footprint of long-distance transportation of foods. Fresh food supplies in urban cities in the US takes advantage of the developing trends among consumers seeking sustainable, fresh, locally grown food supplies. Marine aquaponic systems are capable of producing fresh seafood and plant crops with high market value and strong consumer demand, but few species combinations have been developed well enough for practical applications. In this project, we propose continuing our ongoing efforts to explore marine aquaponics and provide operational guidelines for successful production.

Objective 1 – Complete our developing list of salt-tolerant plant species with a focus on seed availability, recommendations for germination, growth rates, and chemical composition data;
Objective 2 – Evaluate the long-term sustainability of a shrimp/plant marine aquaponic system, and evaluate salinity tolerance of 3-6 halophytic plant crop in marine aquaponics systems; and,
Objective 3 – Determine characteristics of the Asian markets in Chicago for products from marine aquaponic FPS and estimate total poundage of market demand.


Development of Sustainable Aquaculture in Midwest through Improvement of Larval Fish Rearing Stages

Principal Investigator: Karolina Kwasek
Affiliation: Southern Illinois University Carbondale
Initiation Date: 2019

The main bottleneck to further development of sustainable and intensive aquaculture in Midwest is improvement of larval fish rearing technologies and larval fish nutrition. The main objective of this project is to develop detailed protocols for larval largemouth bass rearing in indoor facilities that will help to support high survival and growth performance of this species in its young age.


New Approach in Replacing Live Food – Meeting Largemouth Bass Larvae Growth Requirements using Asian Carp Muscle as an Initial Protein Source

Principal Investigator: Karolina Kwasek
Affiliation: Southern Illinois University Carbondale
Initiation Date: 2018

The objectives of this project are:

  • To develop optimal in vitro methodology for Asian carp muscle hydrolysis using largemouth bass (LMB) endogenous digestive enzymes obtained from adult LMB.
  • To evaluate the effect of Asian carp muscle protein hydrolysates obtained using methodology in Objective 1 as a first feed for larval LMB.

On the feasibility of establishing a saline aquaculture industry in Illinois

Principal Investigator: Nandakishore Rajagopalan
Affiliation: University of Illinois Urbana-Champaign
Initiation Date: 2012
  • Determine the existing and near-term (5-10 years) market for striped bass species in the Midwest region of the US for food consumption
  • Analyze the competitive advantages of rearing a euthyhaline species (Striped Bass) in Illinois/Midwest using regional saline water resources
  • Locate appropriate saline water resources in Illinois and examine water quality for compatibility with striped bass production

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
