流水养鱼在我国有着悠久的历史。据考证,我国著名的风景区——浙江省杭州市,尚有流水养鱼池的遗址,如南齐时代的“玉泉池”及宋朝的“花港观鱼”等。不论何种养鱼方式,其水中含氧量的高低,是关系到鱼类生长与存亡的问题。而流水养鱼最大的特点,就是依据“流水不腐”之论点。流水可经常补足高氧的新水,排出被鱼及其他污染的废水,进行交替更换,使水质保持清新,所以可以进行高密度养鱼,获得高产。 Water fish in our country has a long history. According to research, the famous scenic spot in our country - Hangzhou, Zhejiang Province, there are still sites for water fish ponds, such as “Yu Quanchi” in the Nanqi era and “Huagangguanyu” in the Song Dynasty. No matter what kind of fish farming, the level of oxygen in the water, is related to the fish growth and survival issues. The biggest characteristic of running water fish is based on the “water does not rot” argument. Water can often make up for the new high-oxygen water, the discharge of fish and other contaminated wastewater, alternating replacement, the water quality to keep fresh, it can be high-density fish farming, access to high yield.
