Under the hypoxic and hyperoxic conditions, tomont development was suppressed. Under the anoxic condition, tomonts died. However, when tomonts were transferred into an oxic condition after 2 or 4- week incubation in the hypoxic condition, development resumed, showing a rapid increase in theront excystment rates 10 to 11 days after the transfer."

I phrased that wrong. I should have said low dissolved oxygen is stressful for fish and stress makes the fish more prone to parasites. Higher DO would help the fish be less stressed.
