    Hey guys,

    Went fishing and caught tuna and took some pics. I was just noticing some subtle differences in the fins. Are they all yft?

    Thanks in advance.

    The last fish (the one in the pic with the green spreader bar) looks to be a Bluefin.

    If you fold the pec fin up and it does not cover the eye = Blu Fin
    If it covers the eye Yellow fin Or Big Eye then the next debate,

    This is from two different trips right? Top picture all the fish have longer fins. YFT. The bottom one looks like bluefin. Did it have darker color flesh than the previous tuna?

    Hard to see for sure, but it appears to me that the tunas you are holding (1) do not have "V" notches in their tails, and (2) the pectoral fins are long enough to cover the eye if stretched forward, and (3) the anal fin is much paler in color than the top fin. The dots along the belly are also helpful. I say good job on nice Bluefin tuna!

    And this is why CDFW has such bad filet rules for tuna.

    That second picture is a perfect picture for IDing the fish...... it shows the fish very clearly.

    Yeah there are lots of different ways to check, but among the many, the pectoral fins are a good start............

    Albacore have waaay long pectoral fins (longest of all tuna)

    Bigeye also have long pectoral fins..... second longest to Albacore.

    Bluefin have short pectoral fins, which do not reach the beginning of the second dorsal fin. The picture of the second fish shows clearly a very short pectoral fin.

    Short Pectoral fin - BFT
    [​IMG]

    Yellowfin also have a shorter pectoral fin than Albacore & Bigeye, although their pectoral fin is longer than the Bluefin. The yellowfins pectoral fin will not extend past the anal fin.

    Compare the picture above (Bluefin Tuna), to the other picture the guy posted (below). Look at the pectoral fins of the two tuna where you can see their sides........ clearly you can see the difference in the pectoral fins. Picture above shows a BFT, and the picture below shows at least two YFT.

    He unfortunately has not comeback to say if the fish in the second photo is one of the fish in the first picture. If so I would say yellowfin and a bad angle of the pec fin to tell. If it is not in the first picture then the fin does look short, so bluefin.

    Hey Phil, the last picture is definitely not one of those two tuna in the first pic! There is no bad angle on any of those pics as there often is on some other posts. It's super clear with the straight on shot as to how short that pec fin is on the spreader bar tuna, and how much longer the pec fins are in the other pic ;)

    That second picture is straight up 100% Bluefin Tuna, all day every day...... at least imo right now it is unless proven otherwise :D

    Nope, look at the length of the pectoral fun.

    I am Steve, and it's short as shit. If I am wrong then so be it, but I'm very much seeing bluefin in that picture.

    That pec fin barely goes past the 1st dorsal fin....... it's way short.

    Compare it to the other fish posted in this thread....... there is a clear and big difference between the two different pics and fish..... BIG difference clear as day if you look close enough (actually you don't even need to look that hard). The other fish show the classic signs of a YFT, and the fish with the spreader bar shows the classic signs of a BFT.

    I would call it a YFT. Looks like it has a short fin on one side and a long fin on the other. We caught one like that the other day.
