Sole Source Request to Purchase Experimental catfish diets containing 28% crude protein formulated to contain 3% and 6% lipids

Mississippi State University’s Aquaculture Research Program is seeking a sole‑source supplier to manufacture experimental catfish feed for a commercial‑scale study evaluating the impact of elevated dietary lipid levels on growth, feed efficiency, fillet yield, and overwinter survival. The study requires two custom formulations (≈3% and ≈6% lipid) each containing 28% crude protein, produced in 10‑ton batches to match regional ingredient profiles. Fish Belt Feeds, Inc. is the only regional feed mill capable of meeting the batch‑size, ingredient, and logistical constraints. The university estimates a total spend of roughly $127,500 for about 300 tons of feed. • Feed specifications: 28 % crude protein, 3 % or 6 % lipid, 10‑ton production batches. • Quantity: ~300 tons total (≈30 batches). • Estimated unit cost: $425 per ton (delivered). • Supplier requirement: Ability to produce 10‑ton batches with regional ingredient composition; other local mills cannot meet batch‑size or formulation constraints. • Funding: No external funding source listed; purchase is internal to the university. • Timeline: Procurement notice posted 2026‑08‑28, submission deadline 2026‑09‑11.
