I'm new starter in fish farming and observed the oxygen level is very low cos can see the fish in vertical position most time even though i changed water and cleaned the pond every two days in cement constructed pond of over a year but just stock in fish two weeks now.

If they are standing like that then you have to check the water ph
Make sure the water ph is around 6.8-8.0 it can make them stand too
