How to Rig for Mangrove Jack

Lutjanus argentimaculatus

Mangrove jack are aggressive red snapper of northern and eastern Australian estuaries, living tight to mangrove roots, fallen trees, and rock walls, and sometimes pushing well up into fresh water. They hit hard and immediately run for the snag, so heavy leaders and a locked drag are the only way to land them. Hot summer nights around the moon phases are prime time.
