Topwater fishing weed flats for sea trout is effective and outright fun! Sea trout are ambush predators hiding in thick weeds awaiting baitfish. Here are some ways to improve your catch rate. A big and loud topwater bait with a ‘walk the dog’ action is essential in catching big sea trout. In addition to longer casting distance, big topwater baits create a large disturbance in the water, which will draw sea trout out from the weeds. Adding a feathered treble to the back of the topwater will prompt fish on the chase to bite. Don’t be afraid to work this bait quickly—remember, you are covering large flats, and sea trout are attracted to the quick evasive action of your topwater.
