Can a fish suffocate in water?

The fact that fish need oxygen to live means they can suffocate in a few different ways. Taking a fish out of water will naturally cause it to suffocate, as it isn't able to pull oxygen from the air with its gills. As for how a fish could suffocate underwater, this can happen in a couple of ways.

.

In this manner, does a fish drown or suffocate?

If fish are taken out of water then they'll die, but not due submersion or inhalation of water, so they're not drowning. If there's not enough dissolved oxygen in the water, then they'll die because they can't breathe. To suffocate is defined as to “die from lack of air or inability to breathe”.

Additionally, how do fish breathe in water? Gills are feathery organs full of blood vessels. A fish breathes by taking water into its mouth and forcing it out through the gill passages.
