A large number of limnetic macro algae fossils were found in the Chang6 reservoir in Ansai Oilfield, which proved the existence of macro algae in the Mesozoic.(安塞油田長6油層發現了大量的淡水宏觀藻類化石，證實了中生界宏觀藻類的存在。)

There is the rich limnetic resources in Chinese vast inland water area, the safety of limnetic products have become increasingly prominent problem in recent years.(我國遼闊的內陸水域中有著豐富的淡水資源，近幾年淡水產品的安全性問題日益突出。)

The conclusion is that the sedimentary environment of coal measures in Changyang area, Shuangyang basin is mainly fan delta and limnetic deposits.(得出的結論是：雙陽盆地長嶺區煤系地層沉積環境主要為扇三角洲沉積和湖泊沼澤沉積。)

It is nourished mainly by dead matter that falls from the littoral and limnetic zones and by sediment washing into the lake.(它主要由落從海濱和淡水的區域和由洗滌入湖的沉積的無機物養育。)
