I had this fish a deep color in a nice death circle. Out of nowhere the biggest fur bag I ever seen jumps on the back of my tuna and starts chewing on his head. I buttoned down the drag to full and would get my fish back, put a few winds and he attacked again, again and again.
I never seen that "tuna fishing" before in my 50 years of fishing. I had them eat almost everything else, but not a 150 lb tuna. He was pissed and growled at the crew when they gaffed it,
this^^^ I was on this trip and couldn't get bit on 80.
I got 4 bites on 60. Only one bit through and another sawed off by someone at color. These fish are mean and agree 80 would be better, but just wasn't working for me either.
