Summary
The annual production of 1.3 million tons of salmon in Norway consumes 1.5 million tons of feed. The energy content in faeces and feed spill from land based smolt production is estimated to 242,880 GJ, and 11,785,235 GJ from the grow out phase annually. The corresponding figures for phosphorus are 225 tons and 9,096 tons, respectively. To make wise priorities in investments and technology development, and in making legislation for cleansing, detailed knowledge of the flow of nutrients and energy in salmon farming is required. This report can serve as a guide for prioritising of research and development.
