It's been five years since the Deepwater Horizon oil rig exploded on April 20, 2010, killing 11 workers and triggering the worst oil disaster in U.S. history.

Fears about the safety of eating gulf seafood have eased, and demand for it is there. But the region's fishermen are still struggling to regain their footing.
