I have no idea. I don't keep bluefish unless I'm in a tournament. I know I caught one once in Fire Island inlet, on LI, that had to go over 20 lbs. You know you have a big blue when they get that bulldog head, like a male mahi.
Biggest I ever weighed into the MV Derby was around 17 lbs. It won a daily but not the Grand. That was the year Lori Vandelaske caught one almost 19 on a fly rod.
One year, the day after the Derby ended, there was an all afternoon blitz off East Beach. Almost ever fish was in the teens. I released every one of them. I had two that pulled my Manley hand scale almost to the 19# mark. I was using a big 3M S-glass Lami, and couldn't move either of those fish until they wanted to be moved. No 40# bass ever locked up that rod like that
