What water temperatures do bluefin tuna and yellowfin tuna prefer ?

[NELLIE]

I think yellowfin is 65 degrees but not positive and do not know about bluefin.

bluefin are going to be in colder water 53-62 or so. we have been catching them here in the cape fear region it has been between 54.5 and 58 and some change.

my 2 cents

Bluefin have the ability o regulate their own body temperature, so they are less temp dependent than YFT

Yellowfin in 65-68 degrees is always the ticket although I personally haven't caught many in last two seasons so I have forgotten almost everything i knew about YFT.

Bluefins typically 54-62 degrees. This year all bluefins caught around the hambone, chicken bone, and hotdog were caught below the thermocline in June/July. planer rod or way way way back bait. Did everyone notice how long the BFT's hung around? Seemed like a long time, then they disappeared around end of July and most of August.

YFT's they never really showed. Caught a couple in Oct. during that Rockpile bite.

Go figure as a few years ago we had them ( smaller size bft ) down at the Lumpy Bottom in surface water that got up to 80 degrees but most were caught deep in the colder water but we did catch a few up top trolling wwwwwwback in that hot water. The sand eels were so thick at the LB and they held the smaller bluefin even with the hot surface water. Not sure about the GBT as I they have that thick fat layer and can tolerate much colder water than the smaller ones we catch in the summer months. I have seen yellowfins just flat disapear overnight in our local canyons when a warm Gulf Stream eddy moves in. This happened last season with the early season yellowfin bite that shut down as soon as the 80 degree water showed up. I was there and saw it as you could not get a bite in the warm water and that was the end of any decent yellowfin fishing for us the rest of the season even though the bait was there. It made for some great billfishing but the worst yellowfin fishing in our area in years.
