Very interesting and well thought out replies gentlemen, thank you!
I propose that someone sponsor me a trip to each and every known GT hot spot over the next 6 months and I'll do an in depth study on the matter!!!
Hahahahaha!
In all seriousness though, I'm sure the environment probably has even more to do with it than the water temp.... The GT's on our East Coast live in very much a rock and surf environment, with alot of big waves and swell, and their feeding zone is RIGHT IN THE SURF, up against the rocks... this is a tough environment for any animal to survive, and to be the aplha predator, you have to be tougher than anyone else... And these fish get big and tough.... the largest that I know of taken off the beach/rocks on live bait (bonefish) was over 60 kilos, and the largest on popper around the 55 kilo mark....Big, Thick, TOUGH fish...
The fish in Seychelles on the other hand, although the environment is pretty gnarly too, with 2 and 3 metre tidal movements, the fish were often, not always, but sometimes, significantly "skinnier"... Make no mistake, these fish are still GT's, and they will kick your ass, but the fish you catch inside the lagoons in the atolls, were't as tough as those caught on the outer reef edges which are hunting in the surf zone.....
Anyway, interesting I thought... something else to keep us thinking about anyway....
Janos - Mate, Roosterfish haunt my dreams.... I HAVE to hunt those things one day....
Hows Sverige these days mate?
