Found it:
Girth x girth x length divided by 800= weight
44x44x65/800=157.3lbs.

That is the general formula used for any fish but there are more rigorous scientific verified versions for the highly regulated tuna industry. This equation is specific for blue fin:
Length-Weight estimate Western Atlantic Blue fin (From the journal Fisheries Sciences):
W (lbs) = 0.00004044 * L (inches*2.54)exp2.837 *1.112 *2.2 (lb/Kg)
The 1.112 is conversion from eviscerated weight to whole weight
For example, 65" = 165.1 cm gives a W = 195 lbs
