Catch and efforts in eradication program of largemouth bass (Micropterus nigricans) in Kanabara Dam Lake, Nagano Prefecture, Japan. Operating since 2007, the program includes the removal of spawning beds via snorkelling; removal of larvae and fry through scooping; and capture of immature and adult fish via net traps, cast nets, gill nets, fishing, and spear guns, and by hand. The M. nigricans population was monitored via snorkelling and environmental DNA analysis. Net traps were effective for capturing smaller fish, whereas 3-meter-long gill nets and spear guns were effective for larger fish.
