Phased Evolution from Flow-through to Recirculation: A case study

摘要

Whether due to project capital limitations, uncertainty in future market stability,or nervousness about the technical complexity or mechanical risks associated m with recirculation systems, it is often not feasible or desirable to jump right into a recirculation system when a new facility is being constructed. For many, it is more palatable to evolve from a low-tech to a high-tech system. A common scenario is when the hatchery owners may have inherited an aging flow-through facility or may have constructed a facility with no intention of needing recirculation, but have been motivated towards recirculation to reduce water use, improve control, or reduce production costs.
