Mission Manatee

Mission Manatee is a program to investigate the Estero Bay manatee population and to record and document behavior, scarring, and migration patterns. Through education, we plan to create an awareness and understanding of our endangered manatee.

Protection

The manatee is protected under federal law by the Marine Mammal Protection Act of 1972 and the Endangered Species Act of 1973, which make it illegal to harass, hunt, kill, or capture any marine mammal. The manatee is also protected by the Florida Manatee Sanctuary Act of 1978 which states: "It is unlawful for any person, at any time, intentionally or negligently, to annoy, molest, harass, or disturb any manatee."

Anyone convicted of violating this state law faces a possible maximum fine of $500 and/or imprisonment for up to 60 days. Conviction on the federal level is punishable by fine up to $50,000 and/or 1 year in prison. The state of Florida can pursue prosecution under federal law in circumstances of extreme harassment, resulting in death or injury of a manatee.
