Asian Swamp Eel (Synbranchidae: Monopterus) occurrence data in Florida 1997–2023

Asian swamp eels (Monopterus albus/javanensis) were first reported as introduced to Florida water bodies in 1997 near Tampa and Miami; a third population was recorded by 1999 in Homestead. We used records from continuous long-term monitoring programs, sporadic monitoring studies, and online databases to reconstruct swamp eel presence across Florida from 1997–2022. We used additional records from 2023 and January 2024 to illustrate further range expansions and fill in spatial gaps.Data and figures accompany this publication: Pintar, MR, ND Strickland, JL Kline, MI Cook, and NJ Dorn.
