Increasing oxygen in order to maintain the higher dissolvedoxygen (DO) concentration in the water body is one of the main adjusting measures in this farming mode.
通过向养殖水体充氧，从而使水体中维持较高浓度的溶解氧，是该养殖模式水质管理的主要调控措施之一。

Even though Bettas do well in waters low in dissolvedoxygen, that does not mean they require less oxygen than other fish.
即使斗鱼做好水域溶解氧谷底，这并不意味着他们需要比其它鱼类的氧气。
