I would guess the fish at around 5 years, and that's only a guess.

Soooo disappointed when it came out of the water and I got a good look at it! Still an enjoyable catch and a great fight, but I was hoping for something extraordinary.

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
