There a lot of nice fish here, folks. My personal bests are: two LMB a tick over 20" and 4lbs, numerous Chain Pickerel around 24" and a couple of SMB around 19" / 3.5lbs. Most of the time I catch and release now. We have small slot that we keep for food.
I personally know a guy that caught a 20.5 lb. channel cat while crappie fishing with 2 lb line. There was not even a mention of this being close to any records. I have no idea what the record would be though.
Line class (and all other records for that matter) are listed by species.
A 12lb LMB on 2# line, if not a world records its damn close and for sure a state record assuming he caught it in his home state of NJ as its all tackle records is just 10lbs.
