I would agree with Karstopo. If trout and redfish are there they'll typically hit live bait first, they tend to outcompete hard heads and are more aggressive when they are there. Trout and reds are not always in an area one wants to fish. They move around the bay in different locations based on the season and several other factors. Besides that, ways to increase catches are to be fishing better structure such as live oyster reef and rocks located in the right parts of the area where they are for that season. I'd suggest fishing the jetties for you as a walk in angler. Take your croaker there and while you'll still catch catfish or two here or there, summer is a great time to find predators (trout, redfish, smacks, etc etc.) at the jetties.
Have fun
