The ‘general’ consensus is that live shrimp is the best and most universal inshore bait because shrimp are abundant in the inshore habitat and are universal prey for trout, redfish and flounder. It is also generally agreed that live shrimp are a more effective bait than artificial. Why?
As a kayak angler, my livewell options are limited. So if shrimp are the best bait, which artificial shrimp is best? Recently I have explored this question and herein are my conclusions. I started with the premise that, ‘If it looks like a duck, walks like a duck, and quacks like a duck, then it must be a duck. Or in this case: ‘If it looks like a shrimp, swims like a shrimp, sounds and smells like a shrimp, then most predators will decide that it must be a shrimp’.
Does it Look like a shrimp? According to Wikipedia, shrimp are widespread and there are thousands of species that vary in size, shape and color. Popular shrimp baits are rather distinctive in shape but several vary in size and some have a wide range of colors. I think that the pre-rigged versions have the most realistic shape – but I am not a fish, so what do I know. The picture below includes a few of the most popular shrimp baits that you will find in local stores, so you can decide which ‘Looks’ the most realistic based on the local shrimp in this area!

Does it Swim like a shrimp? In a SaltStrong article, (Best Shrimp Lures To Fish Under A Popping Cork [Brand Comparison] (saltstrong.com) ), Tony Acevedo looked at the action of shrimp baits under a popping cork by filming them in a swimming pool. He rated them based on their ‘action’ on the pop and how they settled in the water. A synopsis of his results in the chart below.

Does it Smell and Sound like a shrimp? As for smell, Berkley Gulp Shrimp and Z-Man Scented ShrimpZ are rated as having the best scent but anglers can add scents such as Pro-Cure and Dr. Juice when they think appropriate. I have found that Fishbites E-Z Shrimp strips are very effective with some lures, however, these may interfere with the action of the pre-rigged lures. Berkley and Vu-Du make shrimp baits with built-in rattles that may that attract fish. In addition, D.O.A. sells rattles that can be inserted into shrimp baits but I would suppose at the risk of affecting action. Also. there are rattles that can be attached ‘in-line’ to the leaders.
All -in-all, there are countless variations among the many shrimp lures. I am not endorsing any of these to work in any particular situation. As Abraham Lincoln once said, “With one lure, you cannot please all of the fish, all of the time”. You be the judge.
