Racer - if you aren't skilled at it yet, learn to throw a 6-foot cast net with good accuracy. Best way to catch reds and trout is with live bait. Finger mullet and/or shrimp. You can catch both on just about any marshy area throughout the summer, just try not to ruin your net on the oysters. A 6-foot net is only effective in about 3 feet of water or less. Deeper than that and you need a bigger net, and those are much harder to throw repeatedly and accurately. You can probably catch all the bait you need off your dock. You can rig up a small bait pen - get a paint bucket with a lid. Drill holes in the bottom and sides. Put lid on, and a couple of pyramid weights in the bottom to keep it somewhat upright. Catch the bait, put in bucket, tie off to the dock. If you have any decent tidal flow there, finger mullet will survive a couple of days. Shrimp will die off more quickly, but can make it a while. If your boat doesn't have a livewell, just bring the bucket and tie off to the boat while you are fishing.
Learn how to hook both the finger mullet and shrimp without killing them, and fish them under a popping cork with about two feet of leader material between the cork and hook. You can use topwater lures in mornings and late afternoons if you find good spots. That is by far the most fun way to catch them. Mirrorlure MR 17s are great during the winter months for trout. Just fish them super slow.
Also, if you have a dock with decent water, get a green LED dock light (you can get ones that mount on the dock and shine down, so you don't get barnacle growth). Leave light on throughout the summer. After about a week, the light will be crawling with bait every night and you can catch as many trout as you want at night. Or, take your boat and find other docks that have the light and fish those at night. Just be careful that you don't fish the wrong guy's dock - some people get pretty sensitive about that type of fishing at night.
And start saving your money because 2-foot-itis is real and never goes away. You are going to want a bigger boat.
