No clue. I caught a 1.60 yesterday, weighed him after my buddy was floored I was about to just drop him back, and said "Need 7 just like him or better, preferably with a kicker, next weekend..."....and my buddy was floored I didn't bother to even take a pic. Usually don't pull the scale out now unless they're close to 2, in a tourny sorting/culling, or someone with me asks.
That mark is around 14" on a fat, well fed female black in March, 15" most other fish in the winter, and mid to upper 15" fish the rest of the year.
