I think my heaviest was 118 pounds... you are right. I was comparing the tuna that I caught to all tuna. I still wouldn’t want to pull a 50 pounder up by hand. LOL!!!
ICBW, but I think even tinker mackerel would fall under the tuna taxa. I’m no biologist, but I do know that they are related to tuna. Also, skipjacks, bonito, and false albacore fall under that taxa and are far short of 50#.
I made my living for a few years working on head boats and commercial pin hooking. Tuna season is how we made it through the winter. When conditions were right and we had them boiling on the surface, we would handline fish up to 80-100#, usually yellowfin or big eye. Longfin were in the 40-50# range. Handlining was much faster than rod & reel and ya had to get 'em while the gettin' wuz good!
