No idea if it is legal! I assume it is so common to try, that the baitfish rules must be clearly addressed in the Alabama regulations?
Can you identify the exact species of fish? I believe that Menhaden Shad are commonly called pogeys, but around the Atlantic seaboard the locals may refer to other fish species as pogeys.
If you get an exact identification, then you can determine if they may reproduce in your freshwater pond. If they CAN'T reproduce, I would think that would be excellent bait.
I have heard of guys fishing for channel cats with goldfish. A few years later, that catfish pond became a significant goldfish pond.
