Brief Project Summary:

The proposed research addresses the need for soybean germplasm with high-value oil quality traits for aquaculture feed. The current soybean-based aquaculture feedstocks lack EPA and DHA omega-3 fish oil fatty acids and other oil-based feed components. Because of these deficiencies, soybean-based aquaculture feed requires supplementation with fish oil and
high-priced astaxanthin flesh pigments, particularly for farm-raised salmon. In addition, oils with enhanced omega-3 fatty acid content are prone to oxidation, which reduces the shelf life of fish due to the development of off-flavors and odors.

Information And Results
Project Deliverables

Aim 1. Developing soybean germplasm with oils enriched in EPA and DHA omega-3 fatty acids.
Aim 2. Optimizing production of astaxanthin in soybean seeds.
Aim 3. Applying emerging synthetic biology techniques to stack EPA/DHA omega-3 fatty acid, astaxanthin, and high vitamin E antioxidant traits into Nebraska soybean germplasm.
Aim 4. Conducting physiological and field-evaluation of new aquaculture germplasm to optimize agronomic performance.

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.
