I think they can shake a jig loose sometimes but it is usually after you tear a hole with the hook then the fish manages to get some slack. If I get one coming in I never let up, keep a bend in the pole and pull them in with no net. Some folks use a net but unless it is unusually large I put them in the boat and many times the hook falls free once they flop in the bottom of the boat. Sometimes they short strike and bartely gets hooked and in they case your just gonna loose a few.
