There are reported fish kills that are a result of the heat and storms.
South and central Louisiana are reporting a rash of fish kills that the state Department of Wildlife and Fisheries blames in part on soaring temperatures and summer storms. The agency said recent kills were caused by hypoxia, a depletion of oxygen in the water. High-temperature water has a low capacity to carry dissolved oxygen, jeopardizing the delicate balance between oxygen-producing and oxygen-consuming aquatic life. Thunderstorms with high winds or heavy rain can send harmful runoff into streams and lakes, causing a hypoxic fish kill. While the sight of hundreds of dead fish floating in the water can be shocking, Wildlife and Fisheries said fish kills often lead to a rejuvenated ecosystem that is healthy and naturally replenished in later years.nola.com
It may be beneficial but with climate change and increased heat and storms we will see more.
