Summer heat brings fish kills in South Florida. Here’s what to do if you see one

MIAMI (FL)June 30, 2025 / 6:45 PM EDT/ Miami Herald - As temperatures heat up, so do the chances of dead fish floating to the surface of South Florida’s waterways.

Fish kills — which can range from a few dozen fish in a small area to massive stinking numbers across large bodies of water — are most likely to happen during the summer when there’s more rain, runoff and sewage leaks, said Rachel Silverstein, the chief executive officer of Miami Waterkeeper.
