Brief Project Summary:

The proposed research addresses the need for development of a complete soybean-based aquaculture feed. The current soybean-based feed lacks sufficient levels of EPA omega-3 fatty acids and other oil-based feed components. Because of these deficiencies, soybean-based aquaculture feed currently requires supplementation with fish oil and high-priced astaxanthin pigments, particularly for farm-raised salmon. In addition, oils with enhanced omega-3 fatty acid content are prone to oxidation, which limits the shelf life of fish due to the development of off-flavors and odors.

Project Deliverables

The goal of this project is to develop soybean lines that provide a complete package of feed quality traits for aquaculture production, without the need for additional high-cost diet supplements. Through the use of genetic crossing and emerging synthetic biology strategies, Nebraska soybean germplasm will be developed with economically sustainable levels of EPA and astaxanthin for broad use in aquaculture feed that will be combined with a high vitamin E antioxidant trait that has been previously developed in the PI's lab to provide oxidative stability to extracted soybean oil and increased shelf-life to farmed-fish.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
