This is much like a real shrimp appears when moving through the sea grass fighting the current.  You will retrieve this lure very slowly. Instead of using a steady retrieve it is best to simply use your rod tip to lift it gently off the bottom and allow it to settle in a new spot while you pull the slack line in.  You will find that this bait is often inhaled while the bait drops back towards the bottom.
 
If you are a fisherman who likes to cast fast moving lures you have success with this species as well.  Crankbaits can be used successfully to catch Speckled Trout under the right conditions.  If it is a calm day I sometimes like to tie on a small crankbait that is designed to float and run no deeper than three feet.  

I will then make a long cast and retrieve the lure in a manner that allows it to just touch the tops of the sea grass.  You accomplish this by adjusting the height of your rod tip.  As you hold your rod tip higher the lure will run shallower, as you drop the rod tip it will dive deeper.  Your goal is to adjust your height of your rod tip to achieve the desired result of allowing your bait to swim just above the top of the sea grass, touching it from time to time.
 
You can of course use other baits for this species.  The tips I have given represent the best success I have had over the years of fishing for Speckled Trout.
