Why are dead fish washing up on shore 2021?

Why are dead fish washing up on shore?
The fish were killed by a so-called “red tide,” a bloom of toxic algae that appears along Florida’s Gulf Coast once a year that can be deadly to sea creatures, and potentially harmful to humans.
What does red tide do to humans?
Wave action can break open K. brevis cells and release these toxins into the air, leading to respiratory irritation. For people with severe or chronic respiratory conditions, such as emphysema or asthma, red tide can cause serious illness.
Why are fish dying in Southwest Florida?

What is the Florida red tide?
Florida red tide is a higher-than-normal concentration of a naturally occurring, microscopic algae called Karenia brevis, often abbreviated as K. brevis. It produces brevetoxins — powerful and potent neurotoxins — that can kill marine animals and be harmful to humans.
Why is there a red tide in Florida?
In Florida, the species that causes most red tides is Karenia brevis (K. brevis). This organism produces a toxin that can affect the central nervous system of fish. At high concentrations (called a bloom), the organisms may discolor the water a red or brown hue.
Why are all the fish dying?
The most common cause is reduced oxygen in the water, which in turn may be due to factors such as drought, algae bloom, overpopulation, or a sustained increase in water temperature. Infectious diseases and parasites can also lead to fish kill. Toxicity is a real but far less common cause of fish kill.
How bad is the red tide in Florida this year?
