When it comes to landing that big fish anglers are always trying to find the lure that will do the trick.
Fish, like all animals, have several senses that they rely on when hunting, the most obvious, and important one, is vision.

Jay Walker, the Director of Operations at Duluth Aquarium says, "The eyes, their sight, they have very good sight, so that's going to be the first thing they are going to key in on."

That's why when you go to the bait shop to buy lures you're bombarded with a plethora of shapes, sizes and colors.
But fish have other senses as well that help them catch their prey, which gives anglers other option besides crank baits.

"Smell, they have really good olfactory senses." Said Walker

Live bait gives the fish something to sniff out, and is usually in their regular diet, which can make for a lethal combination.
But often your options at the bait shop include lures that rattle...so what's that about? After all fish don't have ears.

Walker explains, "Fish have this cool sense called the lateral line that runs down their body and what that does is it allows them to sense pressure changes in the water and sense vibration."

The lateral line picks up on that rattle as your lure swims by. Spinners also create vibrations that can attract fish.
But perhaps the most important tool in an angler's bait box is color.
Most anglers have a favorite color that they swear attracts the fish.

"The best technique for fishing, especially when you're thinking of color is to have a couple different things in your arsenal." Walker said.

Having a variety of options in your tackle box will increase your odds but having the stand–by tools of the trade are equally important.

"Well everyone will always have jigs, they will always have hooks, they are always going to have spinner rigs and then they are going to buy Rapala's." Said Russ Francisco of Marine General.

Rapala's offer some of the most popular lures because they appeal to all three fish senses.

"The sight, the smell, the vibrations, I mean that's all standard, that's going to be there, but the color piece, I think that's the mystery." Said Walker
