Developing and Refining Technologies for Sustainable Fish Growth in Closed Containment Systems - Recirculating Aquaculture Systems (RAS) Provide Control of Water Quality and Temperature to Optimize Fish Production and Health, Provide Barriers That Prevent Escape of Fish and Entry of Pathogens, Contain and Remediate Waste Flows to Curtail Environmental Impact, and Minimize Water Use. Ras Can Allow a Commercial Fish Farm to Locate Where Power, Feed, or Oxygen Is Relatively Inexpensive, Where Environmental Impact Can Be Minimized, And/or Adjacent to Their Primary Markets. However, Ras Are Dependent on Relatively Larger Energy Inputs Than Traditional Flow-through or Net-pen Systems. Thus, Strategies Are Required for Reducing Energy Consumption and Improving Waste Disposal, Which Both Are Major Factors in a Fish Farm's Overall Life Cycle Assessment. in Addition, Production Techniques Must Be Developed to Improve Biosecurity and Reduce Stress and Disease Outbreaks in Fish Cultured in Closed Containment Systems. This Work Will Integrate Research and Technology Advancements, and Resolve Current and Emerging Constraints to the Expanded Use of Land-based, Closed Containment Systems for the Production of Safe and Nutritious Salmon and Other Cool- and Cold-water Species. Objective 1. Develop Technically Advanced, Environmentally Compatible, and Sustainable Closed Production Systems and Techniques. Sub-objective 1.1 Optimize the Cost and Effectiveness of Technologies to Remove Nitrogen and Phosphorus From Recirculating Aquaculture Systems and Their Effluent. Sub-objective 1.2 Increase the Energy Efficiency of CO2 Degassing Technologies. Sub-objective 1.3 Use Refinements in Water Treatment Process Design and Economies of Scale to Decrease the Capital Cost Required Per Tonne of Fish Produced Within Water Recirculating Systems. Objective 2: Improve Salmonid Performance, Health and Well-being in Land-based Systems Through Research on Nutrition, Rearing Environment, and Con
