Most saltwater baits today originated from bass fishing. Bass are predator fish so it makes sense that the same lures would work on saltwater predators like reds and trout.
I use MANY bass lures that work well in salt. Take a look at the Whopper Plopper. That bass lure was killer when it came out and it catches reds and trout as well!
Try anything and everything you have in your bass arsenal and you will be surprised at the bites you get.
Lots of redfish tournaments have been won by throwing crankbaits at the jetties. Cajun Phil Broussard is famous for using that technique. It's not easy fishing if it's windy or lots of boat traffic but there are some real footballs running the rocks in the jetties.
