This is some of the science I have read: Interestingly, western bluefin show a median maturation age of 11-12 (95-100"), while the median bluefin tuna spawning age in the Mediterranean is variable and can occur as young as 5 years of age or even earlier.
So western fish median spawn at 11-12years old at 95-100". I don't believe they spawn for the first time until about 80". So a good chunk of fish that have been around the past few years are coming up on spawning age in the next couple of years.
Once the fish get big enough they will then start heading to the gulf of Mexico to spawn. I don't believe any fish spawn off of NC.
