A fish kill usually happens when there is a decrease of organic nutrients in bodies of water is it true or false?

Answer 2

A fish kill usually happens when there is a decrease of organic nutrients in bodies of water is False.

Explanation:

Low amounts of dissolved oxygen in the water cause many, but not all, fish fatalities in the summer. This can happen due to natural circumstances or as a result of human activity that leads in the addition of fertilisers such as nitrogen and phosphorus to water systems.

The death of the fish was caused by the following factors:

• Reduced oxygen in the water is the most prevalent reason, which can be caused by dryness, algal blooms, overpopulation, or a continuous increase in water temperature.
• Fish deaths can also be caused by infectious illnesses and parasites.
