Bluefin get at least 20 pounds, so this one was pretty small, but fought well on a ten weight. I caught one that probably went 15. These fish are so electric blue that it seems like they're fake. There are truly special fish. The 15 pounder gave me the best strike and ensuing non-stop run, through a small cut and coral heads, that I have ever had. I dropped my other rod, started running after it, was able to land it in the lagoon.
