As an experienced fisherman, my answer would be an overwhelming “YES”.   Until I fish with someone with little to no experience.  Fishing is an absolute blast. Not in the same way as riding a rollercoaster.  Its typically relaxing for most that just want to get out and enjoy the outdoors, or for others, like me, make it a challenge. A thinking game. Cat and mouse, so to speak. Figuring out how to catch the most, or the biggest.

     Back to the issue at hand. Catching bluegill. Bluegill are probably the most numerous and easiest to catch fish that inhabit North America. They are generally regarded as a “survival food source”.  In the various communities that have in their plan to rely on catching their own dinner, bluegill are probably on or near the top of the list.  Survivalist, prepers, (shtf/worl) types, bushcrafters, anyone with a bug out bag, or get home bag, has a fishing kit in there somewhere. The point being, practice. Just assuming that catching a fish is easy may be a mistake. Having seen people fail miserably with modern equipment, in a survival situation failure is always an option. Even for an experienced fisherman like me. I will admit, in the middle of January, its questionably that I can catch a bluegill. To say that I can stand on the bank of a lake with a thin layer of ice 10 feet out and catch a fish of any kind is questionable. At that point I would probably going for catfish, but the point being, knowing what kind of fish, when and where, cant be a mystery. If you cant do it in optimal conditions, you will be hard pressed in adverse conditions.  

So in short, anything in your “plan”, practice. Weather your fishing for fun, or any “what if” scenario, practice. Learning a self-reliance skill is always good, or you may just end up with a new, enjoyable hobby.
