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

Aim 1. Stacking of EPA fatty acid, astaxanthin, and high vitamin E antioxidant traits into a single soybean line for optimized aquaculture feed using synthetic biology tools.
Aim 2. Improved omega-3 EPA and total oil content in Nebraska soybean germplasm.
Aim 3. Improvement of astaxanthin pigment levels in Nebraska soybean germplasm.
Aim 4. Evaluation of new oil traits in aquaculture feeding studies.
