The correct answer is D - throw 'em back.  You will catch more and even if you don't . . . . . so what.  Filetting and moving them is probably a no-no (or at least seriously frowned upon) - I don't know.  Kind of defeats the "fresh fish" dinner objective anyway doesn't it?  Besides, if you're catching walleye on Batch I can almost guarantee walleye on Jesse.

Search your feelings Luke - You know them to be true.
