What is the consequence of hypoxia in aquatic environments?

Hypoxia refers to a condition in aquatic environments where there is a deficiency of oxygen. This low oxygen level can seriously affect the health and survival of aquatic life. Fish and other organisms require dissolved oxygen for respiration, and when oxygen levels drop, it can lead to stress, impairment of bodily functions, and ultimately, death. Species that are not able to escape from hypoxic conditions or adapt to them are particularly vulnerable. Therefore, the potential death of fish and other aquatic organisms resulting from hypoxia is a significant consequence that can alter entire ecosystems, affecting species dynamics, food web interactions, and biodiversity.

In contrast, enhanced fish populations, decreased mortality rates, and improved water clarity cannot logically result from a lack of oxygen. Increased mortality and disorders among aquatic species due to inadequate oxygen supply would instead decrease fish populations over time.
