Why is a dead zone bad?
Dead zones are the most severe result of eutrophication. This dramatic increase in previously limited nutrients causes massive algal blooms. These “red tides” or Harmful Algal Blooms can cause fish kills, human illness through shellfish poisoning, and death of marine mammals and shore birds.
What causes fish to die in the Chesapeake Bay?

When a sudden, large water change occurs, it causes such a drastic shift in the makeup of the water that the fish often cannot tolerate it and they die.
