Partitioned Aquaculture Systems （分区水产养殖系统），
The Partitioned Aquaculture System (PAS) developed at Clemson University combines the process control advantage of recirculating aquaculture with the lower cost of pond aquaculture. Many of the management problems of conventional pond culture are linked to the daily diurnal cycles of oxygen production and the longer term waxing and waning of uncontrolled algal photosynthesis in ponds. The continuous nutrient enrichment of a pond drives photosynthesis; however, unmanaged algal populations in conventional ponds typically yield only 2 to 3 g C fixation/m2 per day. Algal carbon fixation rates can be increased with lowenergy paddlewheel mixing of the bulk pond water. This technique (often referred to as a “high rate algal pond”) can sustain algal yields of 10 to 12 g C/m2 per day. With this increase in algal photosynthesis comes a similar increase
in the rate of pond water detoxification (ammonia removal) and a solar-driven oxygen production system. The PAS superimposes a water velocity field upon the
pond, making it possible to reconfigure the pond into separate, controllable compartments for the processes of fish culture, gas exchange, algal growth and waste
treatment. A high rate of photosynthesis makes possible a solarpowered biological waste treatment capacity that is sustainable (unlike fossil fuel systems). The PAS adapts algal production to produce a sustainable, lowimpact, high-yield, and more controllable fish production process.
分区水产养殖系统（PAS）在克莱姆森大学开发相结合的循环过程控制优势，成本较低的池塘养殖的水产养殖业。许多传统池塘养殖的管理问题挂钩每天氧气生产的昼夜交替和长远的打蜡和不受控制的池塘中的藻类光合作用减弱。连续池塘富营养化驱动光合作用;然而，在传统池塘藻类种群非托管通常每天只产生2至3克C fixation/m2。与低能黑臭散装池塘里的水混合，藻类固碳率可提高。（通常被称为“高速率藻类塘”）这种技术可以维持10到12 g C/m2每天的藻类产量。这个藻类光合作用的增加了类似的增长
