Manatee Boat Strike Mortality and Prevention

Boat propeller strikes are the leading human-caused mortality for Florida manatees, causing preventable suffering and threatening population recovery.

Key Facts

Virtually every adult manatee in Florida bears propeller scars from boat strikes
Fatal boat strikes have killed hundreds of manatees in record warm water years
Slow-speed zones in manatee habitats significantly reduce strike mortality
Manatees cannot hear high-frequency boat engines approaching
2021 saw a record 1,100 manatee deaths, many from starvation due to seagrass loss

Welfare Considerations

Manatee boat strike injuries range from instantly fatal to severely disfiguring injuries that impair swimming, feeding, and thermoregulation. Animals struck but not killed may suffer for extended periods from propeller wounds. The combination of boat strikes and habitat degradation through seagrass loss creates a compounding welfare crisis for this gentle species. Slow-speed zones are highly effective when enforced, but compliance and enforcement remain inconsistent in high-traffic areas.

What You Can Do

Observe all manatee slow-speed zones when boating in Florida waters
Support manatee protection organizations working on speed zone enforcement
Advocate for strong seagrass protection to address the starvation crisis
Report injured or dead manatees to the Florida Fish and Wildlife Conservation Commission
Donate to manatee rescue and rehabilitation programs
