Several possibilities come to mind. I have caught disproportianate fish like that before and most had eyesight problems. I also see something around the tail that looks like some sort of disease.

One thing is for sure. The fish was having a really tough time making a living. With that size head, it is obviously an old fish that had evaded hooks for quite a few years. Being caught twice within 30 days says that it was desperate and had lost its wariness or maybe its ability to recognize lures. It might have been old and had trouble competing. I bet it wasn't much of a fight.
