First of all, what exactly is the problem? Are the fish hitting and missing or are they not hitting period? If you feel like you're missing fish, I'd recommend using higher quality hooks like Mustad Ultra Point or Gamakatsu and using low or no-stretch line like a heavy braid. Don't be afraid to set the hook hard with this heavy line. If the problem is that you're just flat out not getting any bites, start experimenting with a bunch of different lures and colors. In addition to that, try to find some of the heaviest cover you can access. Just remember: don't be afraid to lose some lures with this tactic!
