Question

What happens if fish do not have enough dissolved oxygen?

Answer 1

Obviously, the fish cannot survive.

Explanation:

water quality is based on one of the important criteria called dissolved oxygen(DO). when this level becomes too low it leads to the death of fishes and other aquatic organisms.

Hope this helps:)

Answer 2

Fishes need oxgen to survive hence if there are no dissolved oxygen in their aquatic habitat they will die completely..

Explanation:

Since all living organisms (fishes, including us) need oxygen for survival..

Answer 3

I would say that they would die.

Explanation:

Fish need oxygen to live to perform cellular respiration. If they don't get enough oxygen, they will die as they cannot respire and produce energy.

Fish need oxygen to breathe through their gills like humans breathe through their nose and into the lungs.
