A general rule of thumb in fisheries science is that any more than 20-30% coverage of aquatic vegetation can be detrimental to quality fish production.

What creates a dead zone?

Dead zones are caused by excessive nitrogen and phosphorous pollution from human activities, including: Agricultural runoff from farmland that carries nutrients from fertilizers and animal manure into rivers and streams, eventually flowing into the Chesapeake Bay.

Does algae need oxygen to grow?

Algae and plants absorbs carbon dioxide and give out oxygen but they also return a little carbon dioxide into the atmosphere. Algae also need water and they find their nutrients in the water. Algae give us oxygen and use carbon dioxide. This process is called “photosynthesis”.
