Reply to comment by Kaisermeister in ELI5: Why is it that when fertilizers make their way into waterways, all the oxygen disappears, killing the fish? by Psychological-Dog994

What about setting up at the mouth of the rivers? I imagine the operation would be easier if it was operating in New Orleans rather than Midway.

Eutrophication already occurs at these places, because of, again, overabundance of fertilizer runoff and plankton growth. They often create "dead zones" that cause marine life to suffocate when they pass through.

Right. I'm asking if there is a way to avoid the dead zones by having something further up the food chain eat the algae before the bacteria rots them. Someone had suggested filter feeding shell fish.
