2004 Annual Report 4.What were the most significant accomplishments this past year? D. Progress Report: This report serves to document research conducted under a non-funded cooperative agreement between ARS National Cold Water Marine Aquaculture Center and the University of Maine. Additional details of research can be found in the report for the parent CRIS 1915-31000-001-00D, Coldwater Marine Finfish Genetic Improvement and Production. We are currently engaged in research and have independent interests in marine aquaculture. Both parties are striving to develop improved technologies to solve problems facing the sustainability of marine aquaculture and benefit U.S. producers and consumers. Mutual benefits to both research programs will be achieved through cooperative planning and execution of research activities that address state, regional and national priorities. Both groups have assigned staff members to assist in mutual research planning. Joint meetings have been conducted to discuss resource contributions of personnel, land, equipment, facilities, and other items necessary to support collaborative research. A long-term, multiple year, renewable lease was developed to address joint facility requirements. Shared research infrastructure consisting of a pump house and water storage facility is being constructed at the Franklin, ME location with estimated completion by November 2004. Cooperative research involving ARS and University of Maine scientists will be discussed in collaboration with industry representative at annual meetings and review sessions.
