Lionfish Traps

Lionfish, lured by a sheet of plastic lattice, swim near a trap offshore near Destin, Fla., on July 6, 2018. Scientists are looking at traps as a better way to kill the beautiful but brutally destructive invaders with huge appetites than shooting them one by one with spearguns. Traps could also be used at depths spearfishers cannot reach. (Alexander Fogg/Destin – Fort Walton Beach via AP)
