not saying this to be rude, that's fishing.
I went out with a mate Sunday last week down south, there was 3 of us and we got some pan size snapper, a few pesky leather jacket, and a nice mowie.
I got a PB snapper, just a tad short off 55cm's and going 1.8kg gilled and gutted which i got it weighed at FishFinder
it has got quite a big bump.
I know for a fact myself that the fin are still out there they are spread out though and to prove my point a good mate of mine who has and own's his own tackle shop, he spoke to someone a charter operator, and all he (my mate who work's in his own tackle shop) told and said to me was- a charter operator took a group out and i do know that they were cubing, they raised some large fin (i do not know how many),
they hooked one, the angler fought it for 2 or 2 and a half hours on 24 which i do not know who the angler fighting it was, they got it to the boat, the deckie put the gaff in and i wish i was there but i wasn't and they lost it at the gaff, i do not know how they lost it.
the fin that i speak off it was estimated between 70-80kg's, no smaller, no bigger. 70-80kg's.
i can say two things, 1) i'm sorry for the angler who lost it.
and 2) I'm glad in a way it was not my self cause i would not off been a happy person at all, no question about it. had it off been my self and also depending on how it was lost, i would be
