A LOSS OF DISSOLVED OXYGEN IN THE WATER is the primary and direct cause of death of aquatic animals during eutrophication or what is also known as hypertrophication.
This is the enrichment of a water body with excessive chemical nutrients which can be a problem in marine habitats, as it can cause algal blooms. With this is the occurrence of dense growth of plant life and death of animal life from lack of oxygen.
