** AWARDS ISSUED PRIOR TO JANUARY 20, 2025, WERE FUNDED UNDER PREVIOUS ADMINISTRATIONS AND MAY NOT REFLECT THE PRIORITIES AND POLICIES OF THE CURRENT ADMINISTRATION.** FISH FARMING IN THE UNITED STATES IS FACING CHALLENGES DUE TO THE LIMITED SUPPLY AND HIGH COST OF FISHMEAL, WHICH IS A KEY INGREDIENT IN FISH FEED. THIS PROJECT AIMS TO CREATE A HIGH-QUALITY, AFFORDABLE, AND SUSTAINABLE ALTERNATIVE TO FISHMEAL BY USING BREWER'S SPENT GRAIN, A BYPRODUCT OF THE BEER-MAKING PROCESS THAT IS OFTEN THROWN AWAY. WE WILL DEVELOP A PROCESS TO SEPARATE AND CONCENTRATE THE PROTEIN FROM THE SPENT GRAIN TO CREATE A HIGH-PROTEIN FEED INGREDIENT (HPF). WE WILL THEN TEST THE EFFECTIVENESS OF HPF AS A REPLACEMENT FOR FISHMEAL IN FISH DIETS THROUGH FEEDING TRIALS. ADDITIONALLY, WE WILL ANALYZE THE COSTS AND BENEFITS OF THIS NEW TECHNOLOGY AND SHARE THEIR FINDINGS WITH THE INDUSTRY TO ENCOURAGE ITS ADOPTION. BY THE END OF THE PROJECT, WE WILL HAVE AN ECONOMICALLY FEASIBLE AND ENVIRONMENTALLY FRIENDLY METHOD TO CONVERT BREWER'S SPENT GRAIN INTO A HIGH-PROTEIN POWDER THAT FISH FARMERS CAN USE INSTEAD OF FISHMEAL. THIS WILL BENEFIT BOTH THE FISH FARMING AND BREWING INDUSTRIES IN THE UNITED STATES. THE FISH FARMING INDUSTRY WILL HAVE ACCESS TO A HIGH-QUALITY, SUSTAINABLE PROTEIN SOURCE FOR THEIR FISH FEED, WHILE THE BREWING INDUSTRY CAN POTENTIALLY EARN MONEY FROM THEIR SPENT GRAIN, WHICH IS CURRENTLY CONSIDERED WASTE.
