Silver spoons seem to work best when fishing for speckled trout. You can purchase them at your local bait or outdoor store and they're relatively cheap. A variety of weights and sizes of spoons can be found and there's no certain one that is better than the other, when fishing for trout. Spoons seem to be quite effective, especially when the weather is warmer. When reeling in your silver spoon, change up the depth and the speed of the retrieve.
When the weather is cooler, fishlike lures seem to be rather effective in catching speckled trout. When fishing with these type of lures, it's best to retrieve the lure slowly, keeping it off the bottom, to entice the fish to bite. When using fishlike lures, change your retrieve, color, weight and size of the lure, to have a better chance of enticing a trout to bite your bait. There is a wide variety of these lures to choose from and if you're unsure of which one to choose, ask the locals what's working best for them.
Jigs are a great artificial bait to use to catch speckled trout, especially worm jigs. This is another bait that's best fished with a variety of action, colors and depths. Jigs can be use with or without using a cork. These type of baits are rather effective when used at night under lights where the trout are congregating to feed. Colors such as white, bright pink, brown and dark red, are proven to work well, in catching speckled trout.
