Every now and then I get asked the question; "Do your baits contain salt?" The answer is the same..."why would they?" Salt, if you did not know will dissolve in water in approx. 5 seconds because of its chemistry... then you are left with salt water because the chemistry. Let me break that down for those that do not believe that.
Salt (sodium chloride) is made from positive sodium ions bonded to negative chloride ions. Water can dissolve salt because the positive part of water molecules attracts the negative chloride ions and the negative part of water molecules attracts the positive sodium ions. Did you know that combining salt into plastic actually breaks down the plastic composition? In my own words...it weakens the plastic.
Some Finesse anglers have been known to run their baits (that contain salt) under tap water and rub the salt out. Why is that? Because salt has a higher density than water that makes the bait sink. That is generally not a preferred type of finesse bait. Check this out...
It is easier to float objects in seawater than in fresh water. Many humans can “float” in seawater but not fresh water. The reason is that water with salt in it, is more dense. So objects that cannot float in fresh water may be able to float in seawater. Floating refers to having a substance rise to the top of another substance. For example, a balloon with helium will float in air because it is lighter (or less dense). If you forced an object to go under the water and let it go, it will float to the top.
So if you have a bait "loaded" with salt and you toss it out, in theory this could happen: the salt would dissolve in seconds surrounding the bait turning the water to saltwater causing the bait to become less dense than the surrounding water. Now this is not likely going to happen because it would be about .125 of a second and then it would dissipate.
Then there is the argument that it acts as an attractant. Not buying that one either. The "taste" of something comes after you put into your mouth, and I am sorry but fish are not that smart to look at something and say, "Hey I like that salty flavor these baits have."
So my point to all of this is...why would Big Sexy Baits salt their baits when we have both buoyant and sinking plastic??? I wouldn't. It is pointless.
