Blackfin

A nice 18 pound blackfin tuna caught just off Islamorada last winter. These fish are sometimes caught while sailfishing. This one ate a live ballyhoo.

  2. Jackson-I always look at the pectoral fin to help determine tuna species. Up north if the pectoral fin does not reach the second dorsal it is a bluefin tuna. If it passes the second dorsal when laid flat against the side it is a yellowfin. If the pectoral fin is very very long it is a longfin albacore tuna. In the keys, we mostly catch blackfin tuna so identification is easier. That being said I have caught a few small yellowfin tuna in the keys as well. Capt. Joe
