Fish Kills in Florida Freshwater Systems


A fish kill is an event in which dead or dying fish are observed in a lake or waterbody. Some fish kill events involve small numbers of fish and others may involve hundreds, or even thousands of fish. There are many factors that can contribute to a fish kill.
This pamphlet was created to explain the most common factors and how they affect Florida’s freshwater systems. It includes discussion of both natural and human-induced causes, as well the effects that stress can have on fish — a component of virtually every fish kill situation.
