Flounder are found at the bottom of the ocean and in fast moving water that collect garbage and fish bait. The best time to catch flounder is when they are migrating, that is, starting in September and continuing through the end of November. The fishing season for Summer flounder however is May to September.
      The tackle recommended for flounder fishing by experts is a medium stiff casting rod that is about seven feet long. Some of the factors to consider when selecting flounder rigs are water depth, current and bottom terrain. Make sure that the rig can get the bait down to the bottom. The bait for flounder can be a finger mullet between three and four inches long. Try bigger bait if you want to attract bigger flounder. Big flounder love long, slender and flowing strips of squid. The problem however with long baits is, the fish will bite the tail end without getting hooked. This is because the average angler with yank the rod once they feel a bite.
      To enhance the chances of getting a big flounder use a two hook system. Use the first hook as you would normally and then take the second hook with bait that still flows naturally and hook it to the tail end of the long bait. The key is to use a large hook suitable for a large flounder but at the same time good enough to allow that bait to flow naturally in the water. Allow time for the fish to eat the bait until it gets the hook in its mouth before you pull up on the rod.
