Florida Manatee Protection Laws: Violations, Penalties, and Reporting

Florida manatee protection laws make the entire state a manatee refuge, so it is illegal anywhere in Florida waters to harass, touch, feed, chase, injure, or kill a manatee, and illegal to exceed posted speeds in the zones where they travel. Penalties run from boating citations for speed violations to state misdemeanor charges for harassment, and federal law can add civil fines up to $65,653 per violation or criminal penalties of $50,000 and a year in prison. If you boat, dive, own waterfront property, or run tours in Florida, the rules below are the ones that keep you out of trouble.

What You Cannot Do Around a Manatee

Florida law makes it illegal to intentionally or negligently annoy, molest, harass, disturb, injure, capture, pursue, hunt, wound, or kill any manatee, or to possess any manatee or manatee part.¹ In practice, that rules out a longer list of behaviors than most boaters expect:

Feeding a manatee, including giving one fresh water from a dock hose.²
Chasing, cornering, or blocking a manatee’s path.
Poking, prodding, riding, grabbing, or standing on one.
Separating a mother from her calf.
Revving a motor near a group of them or persistently approaching a resting animal.

Federal law reaches the same behavior through the Endangered Species Act and the Marine Mammal Protection Act, which prohibit any “take” of a protected animal. Take is defined broadly enough to cover harassment that disrupts feeding, nursing, sheltering, or migration, not just physical injury.³⁴

Crystal River’s Kings Bay is one of the few places in the country where you can lawfully be in the water near manatees, and even there the rules are strict. The federal refuge regulations prohibit chasing, touching a resting or feeding manatee, diving onto one from the surface, cornering or surrounding one, or riding, grabbing, or standing on one.⁵ You can passively observe a manatee that approaches you. Initiating contact is federal harassment.

Boating Speed Zones

Boat strikes are a leading cause of manatee injury and death, and Florida enforces posted speed zones wherever manatees are known to travel or gather. Two zone types do most of the work:

Idle Speed, No Wake. Your vessel moves at the slowest speed that still lets you steer. No wake is permitted.
Slow Speed, Minimum Wake. Slightly faster, but the boat must stay fully off plane and produce minimum wake.

Some zones apply year-round; others kick in during winter when manatees crowd into warm-water areas like the Indian River Lagoon, Crystal River, and Tampa Bay. In Kings Bay, slow speed applies throughout the refuge all year, with a narrow exception near Buzzard Island during summer daylight hours.⁵ Signs mark every zone, and not knowing about a posted restriction is not a defense.

The federal government can also designate manatee sanctuaries, which ban all waterborne activity, and refuges, which restrict specific activities. In an emergency, the U.S. Fish and Wildlife Service director can create a new protection area without the normal rulemaking timeline.⁶

Penalties Under Florida Law

Speed Zone Violations

Exceeding a posted speed in a manatee protection zone is a civil infraction handled through a boating citation, not a criminal charge.¹ Refusing to accept or sign that citation, though, is a second-degree misdemeanor with up to 60 days in jail and up to $500 in fines. Sign the ticket and fight it later.

Harassment and Restricted-Area Violations

Harassing, disturbing, or injuring a manatee is a misdemeanor under the Florida Manatee Sanctuary Act, and so is entering a posted “No Entry” or “Motorboat Prohibited” zone.¹ A blatant or willful No Entry violation can be charged as harassment, carrying the same penalties as directly disturbing an animal.

One narrow exception applies: you may enter a restricted zone or do something otherwise prohibited if it is reasonably necessary to prevent loss of human life, help a vessel in distress due to weather, or render emergency aid.

Federal Penalties Stack on Top

Federal charges can be added to state ones for the same incident, and the numbers are larger.

Under the Endangered Species Act, a knowing violation of the take prohibition draws a criminal fine of up to $50,000 and up to one year in prison. Knowing violations of other ESA regulations reach $25,000 and six months.⁷ Civil maximums have been adjusted for inflation. As of 2026, a knowing violation of the ESA take prohibition can draw a civil penalty of up to $65,653 per violation, other knowing violations up to $31,513, and even unintentional violations up to $1,659.⁸

The Marine Mammal Protection Act adds a civil penalty of up to $10,000 per offense, with each unlawful taking counted separately, and a criminal fine of up to $20,000 with up to one year of imprisonment for knowing violations.⁹

Federal authorities can also seize vessels, motors, nets, traps, and other equipment used in the offense. Forfeiture proceeds through criminal, civil judicial, or administrative channels depending on the case.¹⁰

If Your Boat Hits a Manatee

You are legally required to report the strike immediately. Call the FWC Wildlife Alert Hotline at 888-404-FWCC (3922); cell users can also dial #FWC or *FWC.¹¹ Stay in the area if you can safely do so. Do not try to touch, restrain, or move the animal. Doing that can worsen its injuries and can be charged as a separate violation.

The FWC dispatches trained responders to assess and rescue the animal. Leaving after a known collision can turn an accident into a knowing-violation case if investigators conclude you were aware of the strike.

Reporting Someone Else’s Violation

The FWC’s Wildlife Alert Reward Program accepts tips about reckless boating in manatee zones, harassment, and habitat destruction through the same hotline, 888-404-FWCC, or online. Tipsters stay confidential, and information leading to an arrest or citation can earn a reward of up to $1,000.¹² Useful reports include location, time, vessel or subject description, and any photos or video.

Waterfront Construction Is a Separate Track

If you are building a dock, seawall, boat ramp, or anything else that involves dredging or filling, manatee rules reach you through the permitting system rather than the boating rules above. State work requires an Environmental Resource Permit from the Florida Department of Environmental Protection or a water management district, and federal work requires a permit from the U.S. Army Corps of Engineers, handled through a joint application.¹³ Minor projects can sometimes use a State Programmatic General Permit that skips a separate Corps review, but that shortcut is not available in designated critical habitat areas.¹⁴

Marine construction in manatee habitat commonly requires a trained on-site spotter. Standard protocols stop all in-water work when a manatee comes within 100 feet of the project, and work cannot resume until at least 30 minutes after the animal leaves.
