UNSPSC 10121701: Fresh or frozen brine

UNSPSC 10121701 Fresh or frozen brine, a Commodity code, classifies specialized aquaculture feed products — extruded pellets, formulated diets, and starter feeds for farmed fish including trout, salmon, and catfish. State and local governments procure these products primarily through their natural resources and fisheries management agencies to support public fish hatcheries, aquaculture research programs, and population management initiatives. The issuing bodies are predominantly state departments of natural resources and state universities operating hatchery or research facilities; recent solicitations show activity from Georgia Department of Natural Resources, Illinois Department of Natural Resources, South Dakota Office of Procurement Management, and Mississippi State University. The work entails supplying feed meeting detailed nutritional specifications — protein ranges from 45 to 55 percent depending on formulation, lipid content 15 to 20 percent minimum, fiber under 1.5 percent, and moisture capped at 12 percent — along with performance standards such as slow-sinking flotation characteristics and probiotic or immunostimulant additives. Vendors must maintain product liability and workers compensation insurance and comply with state procurement preferences where applicable.

Recent activity spans the Southeast and Upper Midwest. The State of South Dakota Office of Procurement Management issued IFB 26IFB19839 for annual trout and salmon food delivery to state fish hatcheries, with bids due June 24, 2026, applying South Dakota preferences for resident businesses and in-state manufactured goods. The Illinois Department of Natural Resources issued IFB 26422DNRRESCOB52377 for a four-year fish feed supply contract to Little Grassy Fish Hatchery in Makanda, Illinois, with bids due May 27, 2026, requiring vendors to supply multiple formulations in 30–60 pound bags delivered within five days of order, with approximately three shipments annually. The Georgia Department of Natural Resources posted RFQ 46200ERFQ0019742027 for extruded trout feed on September 15, 2026, with responses due October 8, 2026, open to all qualified suppliers. Mississippi State University issued a sole source procurement (9250-27-R-RFIN-00011) for experimental catfish diets at approximately $127,500 for 300 tons of specialized feed formulations, sole-sourced to Fish Belt Feeds, Inc., in Moorhead, Mississippi, with proposals due September 17, 2026.
