Winyah and Santee Bay help?

[breambuster]

Been fishing a few times this year and all i can catch worth keeping are croakers. I've been fishing around oyster beds, docks and any other structure i can find and have been having no luck. Usually i use shrimp or mud minnows and occasionally an artifitial minnow. looking for spot tail, flounder , any thing but a croaker. any good tips?
