Grass carp captured in the Sandusky River, OH, USA, during 2020–2023 using electrofishing and combination methods

Data were collected during efforts to remove invasive grass carp (Ctenopharyngodon idella) from the Sandusky River, OH, USA during 2020–2023. The data includes the number of grass carp captured, capture method, total vessel hours, removal effort year, removal effort month, number of non-target species captured, and river kilometer (distance from the river mouth measured in 0.5 kilometer units). Data include non-spawning grass carp removal efforts from the lower 24 kilometers of the Sandusky River using electrofishing and combined (i.e., electrofishing around a trammel net) removal methods when vessels were working independently.
