The Northern Snakehead is popular with sport fishermen. Fishermen are required to kill them when caught (Delaware Department of Natural Resources and Recreation 2023, https://fishspecies.dnrec.delaware.gov/FishSpecies.aspx?habitat=1&species=43); The New Jersey Fish and Wildlife website lists only 4 catches between 2014 and 2018 ( https://www.nj.gov/dep/fgw/pdf/delriver/artdel_sp_no_snakehead.pdfi). Fishermen are also required to kill them in Pennsylvaniahttps://www.fishandboat.com/Fishing/All-About-Fish/Catch-PA-Fish/Pages/Snakehead.aspx ) | ||
