Yes and no. Hogs sort of fall into their own category, but you still need a hunting license to shoot them. Unlike coyotes, which you do not need a license to shoot. A landowner can get a depredation permit if he can show that the hogs are causing damage to his land and shoot hogs without a license, but he has to have that permit.
Just to complicate things, wild hogs are also classified the same as domestic hogs to eliminate the sale of them to hunting ranches and slaughter houses. People do it all the time, but if you catch a wild hog in a trap, you have to prove that it has all the shots that a domestic hog has if you want to sell it. The process, in my opinion, was created to eliminate any loopholes that people were using in selling wild hogs for profit and saying they were domestic pigs.
Even hiring a trapper to come in and trap them has issues. I don't know of anybody enforcing them, but I do know of some trappers that are trapping the hogs for free to avoid the regulations that come with the sale of wild hogs.
It really comes down to whether you think the risk of getting caught outweighs what you can make off of selling them. And if you have a Game Warden in your area that is looking for a reason to see what you are up to. The wardens have almost unlimited power, they can do pretty much what they want without a warrent. I try to avoid dealing with them and sure don't want one curious about what I'm doing.
In my years of hunting, I've been stopped and checked by them dozens of times. I've never been issued a fine or written warning, but have been advised a time or two that I was doing something wrong. There are too many laws to know them all and they hold all the cards.
