看看美國怎么給魚分級

這是美國Clear Spring Foods,Inc的養(yǎng)殖場，看別人怎么給魚分級。（轉(zhuǎn)自新浪微博博友 湖北FishMan110）

這個(gè)有意思，呵呵

能讓作者完整呈現(xiàn)一下嗎？多發(fā)點(diǎn)圖片�。〖狱c(diǎn)解說詞！

確實(shí)需要解說。

看看微博上多說些什么吧。

Partitioned Aquaculture Systems （分區(qū)水產(chǎn)養(yǎng)殖系統(tǒng)），
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.

魚也要分級，這么講究，還是第一次聽說，國內(nèi)流行這樣做嗎
