What is the darkest blue everyone has caught? I caught the fish in the attached pics this past weekend. The story is in the Looper Rigs section since it was caught with a Looper Rig. Anyways at first I thought it was a large channel but after looking past the brown color the anal fin is that of a blue. Is this just a dark/brown blue cat or maybe a halfbreed? Anyway it goes it was my largest of the year.
