Abstract
On a kg of smolt produced basis, the six rearing options showed a wide range in performance. The reuse system had the lowest water (2 m3 kgâ 1) and land (0.13 m2 kgâ 1) requirements and the third lowest total energy requirement (288 MJ kgâ 1). The partial reuse system had the second lowest total power requirement (276 MJ kgâ 1), a low land requirement (0.21 m2 kgâ 1), and moderate water requirements (33 m3 kgâ 1). The partial reuse with temperature control had the second highest total power requirement (657 MJ kgâ 1) and land and water requirements similar to the partial reuse system without temperature control. The flow-through system with pumped water supply had the highest water (289 m3 kgâ 1), land (2.19 m2 kgâ 1), and energy requirements (786 MJ kgâ 1) of any of the rearing options. By comparison, the flow-through system with gravity water supply had the lowest energy requirement (218 MJ kgâ 1), a moderate land requirement (0.78 m2 kgâ 1), and a high water requirement (214 m3 kgâ 1). The ranking of the six rearing options based capital and operating costs are likely to be quite different from those based on energy, water, and greenhouse gas emissions.
