[DC] Can aquaman drown?

I know this sounds silly but bear with me. 

Fish technically can drown, but not in the same way we do. They breathe by having water move across their gills, but if the gills are damaged or water cannot move across them then the fish will suffocate.

Would Aquaman face a similar problem, or would his Atlantean biology save him?

Fish breathe water by filtering oxygen out of the water that passes through their gills. In theory you could take all of the oxygen out of the water and he would suffocate just as any human would when there's no oxygen in the air.
