When oxygen levels are high people tend to get a 'high' sensation. When the oxygen levels are low, it feels like you are going to pass out. There are other ways to tell, but generally you would need prodigious equipment, that is most likely very expensive.
Other factors must have caused the low dissolved oxygen levels. Bacteria and other organisms can lower the dissolved oxygen of water when they respire aerobically.
if the oxygen levels are too low, your muscles won't get the oxygen they need from the blood cells. if the carbon dioxide levels are too high, well, carbon dioxide is a waste product, the same thing will happen. this is why when you hold your breathe you pass out. if the muscles don't get the oxygen they need they can't move.
When oxygen levels in water get low... When algae takes over a lake. The oxygen levels will get low.
it is because catfish can survive in low-oxygen levels. Trout survives at higher oxygen levels
Imo, levels are more legitimate than they are low
Low oxygen levels cause vasodilation in systemic arterioles.High oxygen levels cause vasodilation in capillaries in the lungs.
The correct name for low levels of oxygen in the blood is hypoxaemia. Low levels of oxygen in the body tissues is called hypoxia

Yes they are. Is that your question?
