THE MAIN OBJECTIVE OF THE LUMPFISH PROJECT IS TO ADDRESS EXISTING LUMPFISH CULTURE GAPS AT THE HATCHERY, PROVIDE REARING PROTOCOLS AND GUIDELINES THAT ENABLE THE DEVELOPMENT OF A NORTHEAST LUMPFISH HATCHERY, AND PROVIDE THE SALMON AND STEELHEAD TROUT INDUSTRIES WITH FEASIBLE TECHNIQUES FOR USING LUMPFISH AS CLEANERS SO THAT SEA LICE MITIGATION COULD BE LESS COSTLY AND MORE SUSTAINABLE.FOR THE WASTE-SLUDGE REUTILIZATION PROJECT:IN YEAR 1, WE WILL CONDUCT A SERIES OF EXPERIMENTS TO DEVELOP OPERATIONAL AND DESIGN DATA TO DEVELOP STANDARDIZED DESIGNS FOR COUPLED AND DECOUPLED AQUAPONIC SYSTEM WHICH WILL ADDRESS THE ECONOMIC NEEDS OF AQUACULTURE PRODUCERS FOR THE PURPOSE OF IMPROVING THE ECONOMIC SUSTAINALBILITY OF AQUACULTURE IN THE NORTHEAST. IN YEAR 2, WE WILL USE THE RESULTS FROM YEAR 1 STUDIES AND PROVIDE THE STANDARDIZED DESIGNS FOR COUPLED AND DECOUPLED AQUAPONIC SYSTEMS. WE WILL USE THIS INFORMATION TO DEVELOP AN ENTERPRISE BUDGET FOR GROWERS TO ESTIMATE PROFITABILITY BASED ON GROWING SYSTEM CHOICE. WORKING WITH COMMERCIAL PARTNERS, WE WILL INSTALL OUR SYSTEMS DEVELOPED IN YEAR 1 AT COMMERCIAL SITES AND EVALUATE THE PERFORMANCE AND PRODUCTIVITY UNDER ACTUAL COMMERCIAL PRODUCTION SETTINGS. BUILDING ON ALL OF THE PROJECT ACTIVITIES, WE WILL FINALLY TAKE OUR RESEARCH AND PRESENT OUR FINDINGS VIA CONFERENCES AND TWO NEW WORKSHOPS TO BE HELD AT UNH RECIRCULATING FARM GREENHOUSES AS A REVAMPING OF THE ANNUAL CORNELL UNIVERSITY SHORT COURSE TO PROVIDE DIRECT TECHNOLOGY TRANSFER AND MORE IMPORTANTLY, A FULL-SCALE HANDS-ON LEARNING EXPERIENCE FOR NORTHERN PRODUCERS.
