funny, I was just reading Eddie's post & wondering the same thing!
It sems in comparing gulf yft's to Pacific yft's, a 100# fish from the gulf has sickles 2' long or longer, while most 250+lb. yft's I've seen from the Pacific
have sickles barely 12" long?
I was wondering about the Allison's thing, but I really don't know the physical, range, foodsource, temp differences between them.
Hey Pope! can you help us out on this one?
I've looked @ a few of his pics, & it seems they're the shorter-fin models, too.
Matter of fact, I haven't seen any YFT that grow bigger sickles than in the gulf, other than the pics I've seen from the Mediterranean.
Shanker's theory sounds plausible since you'll actually see YFT of the same size in the GOM and some will have longer sickles. Since YFT are one of those species that have indeterminate growth rates they can get as big as food supply permits. 2 fish of the same size may be of different ages.
the sickles in the gulf are bigger than ive seen elsewhere....pacific or northeast. i would be curious to see whether bigeye have longer sickles here than up north.
Only large Big Eye's (80bs+) I have seen in person had sickles comparable to that of a bluefin.
This isan interesting topic. It could be a lot of different variables...
Yellowfin are unique w/ their sickles. much like true albies have super-long pectorals.
the real question is why the difference in sickle length in YFT in the Gulf?
actually, they all seem the same everywhere else EXCEPT here & the Med.
maybe water temp. ck out the 70#er in my avatar- virtually nothing, but a 100#er that I caught
in port A in '06 had sickles 18" long.
This is also a hotly debated topic in South Africa. We primarily get Yellowfin. Occationally BIG-EYE is also taken. may of the older anglers claim that if the sickles are small on a large tuna, that it is a Big-eye.
I've caught YF's with long sickles as well as VERY short sickles, on the same day, from the same school of fish. They both look identical, except for the length of the sickles.
I'm also completely stumped as to why certain fish have much longer sickles than others, for the same size of fish.
Now compare the above photo's of 150-210lb'ers to the sickles on this 150-160lb'er:
did you mean comparable to a yellowfin? yellowfin and bluefin sickles are much different.
Ya I meant comparable to YFT. It seems that most true bigeye taken have short sickles.
Like Capt Eddie said. 200 class Bigeye with short sickles.
In another case in point. The "cow" tuna my dad landed in PV was taped at about 270# it has shorter sickles than a 97# I landed in the gulf.
I don't have enough first hand information to make what I would call and educated guess... But I would say that to me it seems to be a difference in Gulf and other places.
