Jack Crevalle migration calendar.
Jacks travel in schools and announce themselves by busting bait on the surface. Cast topwater plugs, big spoons, or live mullet into the school. They pull harder than almost anything their size — and they cruise inshore beaches, inlet mouths, and bay flats.
Stable. State-managed — most states have minimal size and bag restrictions.
