It depends on what you'r trying to achieve by using salt. When pouring sticks, salt is used primarily to make the bait sink. Some people also think that salt tastes like blood and the fish will hold onto the bait longer. I don't know for sure about that. What I do know is, that if you mix salt in when you cook the bait, the bait will lay flat on the bottom. Without salt, the bait will stand straight up and be more visible. Some people mix salt in with almost everything. Some people don't use salt at all. Some roll their baits in salt for packaging purposes. Experiment and see what works for you. What kind of bottom does your local waters have? Will the bait get lost when it hits the bottom? Maybe you could find out what the locals are using and see what characteristics those baits have.
