Uncut angling fished for them in this video and caught 8 or so fish, most around 32, one 34.5, one 35.

I'm not posting to defend my fish, I know there are lots of these master angler cats (uncut angling caught 2 that one video) and much bigger out there. It is a nice fish but nothing special.
35 inches definitely isn't the average though, there are tons of 32 and smaller fish caught meaning tons of 38+ inchers would have to be caught if the average was 35 inches.
