    Thanks Owyn! Thank all the guys and gals over at NOAA for protecting the resource. I had no idea that it takes that long for a BFT to mature. I really don't think any of us knew that. Knowledge is key.

    Yes, 1 200# BFT would be way more then enough for me.

    Overfishing has nothing to do with the amount of big tunas in local waters.

    Downtown San Diego had a cannery row at one point. Now guys are stoked to go south of the border in hopes of catching one fish. This guy's actually doing lab based research to gain info so the decline can slow and recover before it's decimated. I applaud your work, screw the haters.
    Oh and White Sea Bass made a return on there own too, science had nothing to do with it.

    Owyn, thanks for your expertise in trying to further the science and the public's understanding the dynamics of the blue fin fishery. Owyn and the scientists he collaborates with at Southwest Fisheries Science Center (SWFSC) know more about fisheries biology and management than the average person can fathom. They study a multitude of various marine species, but of course, commercially valuable species often take the spotlight, such as blue fin. These people all love fishing, and are ultimately are interested in protecting and sustaining a common resource for the benefit of all. Owyn and his colleagues are smart people, all you have to do is read their journal articles. Just search Owyn on google scholar and you can see his work. Any cooperation given on behalf of the sport and recreational fishing fleets is an investment in the future of a resource that we can all enjoy for generations to come if managed wisely. See you in Baja...

    Your post and sharing of information are greatly appreciated and interesting. The point of view from a sportfisherman, is imposing limits on us is not affecting the fishery in the slightest. Our take, as compared to commercial, is not substantial enough to affect populations of a highly pelagic fish. Sport caught fish are not being sold for profit, so the impact is not affecting anyone economically.
    The enemy are companies such as Mitsubishi who are spending BILLIONS to ensure the collapse of the fishery and overfishing of bluefin. All the quotas in the world wont change this until the economic motive is removed.
    Most fishermen understand the value of the resource and take only what they need. There are 200lb fish off our coast now, absolutely not because of limits placed on sportfishermen.

    Nice fish! The line of work you do is interesting. Do any of the major sportboats get involved with donating fish for data?

    NOAA is the only chance our fishery has. Yes the restrictions on areas are a bitch!!! It's a shame I have to go across the border to catch cow cod!?? But just because other countries keep everything. If we did to??? Be worse. Btw how much tuna do you need to eat?? If it's just about that ?? I promise if you took all the money you spend on fishing and just bought fish???? You would have plenty!!!

    Hey guys,

    Thank you to those of you that have donated carcasses in the past week! Keep them coming!

    Here is a picture of the gonads on a 110 pound female...

    If you guys catch any female fish over 100 pounds please try to keep the gonads and heads for me! The gonads are tucked up and run parallel along the spine so they are often cut off or lost when filleting....

    thanks again and see you on the water this week!

    Owyn

    If they raised the limit I could bring you more. In the name of science of course. ..

    Rabid Fish speaks the truth! NOAA is not on your side, as a Sportfisherman, whatsoever!

    why is mortality not in the equation?

    Why do you say that mortality is not used in population studies? I am no biologist but read quite a bit on the studies done on our local gamefish and from what I read mortality IS factored in research on population and recruitment studies.
    Only problem I see with the work Owen was/is doing is the quantity of the sampling certainly not the scientific method used. Here is a link to some similar work on local BFT/Albacore/Bonito diets with a bigger sampling albiet from the late 1960s:
    http://content.cdlib.org/view?docId=kt8290062w&brand=calisphere&doc.view=entire_text
    Although you may not agree IMO when there is a lack of real science logically one would factor in all the known info on the biology and add factors such as economic impact (which NOAA does) then choose a plan to conserve the resource as much as possible. That gives the best chance for a healthy resource.
    It would be great if NOAA had the funding to do all the research needed to give us answers to all the unknowns about BFT. Given the complexity of the factors it woukd be a bunch of money and even then it would take time.
    For those who say that the BFT resource is fine based on the last 2 years of great fishing here in SoCal your missing the fact that it seems many fish populations flucuate greatly over decades even centuries with no impact from man. Sardines are a good example:
    http://www.calcofi.org/publications/calcofireports/v33/Vol_33_Baumgartner_etal.pdf
    https://phys.org/news/2017-02-methods-discern-extreme-fluctuations-forage.html
    As the forage goes so goes all those who depend on it. While Owens sampling may be limited it seems in line witht the previous work done in the first link I gave.
    In the past too many fisheries have been managed based on commercial take and action was only taken when a serious decline had already happened. A piss poor way to do it. With work such as Owen's and others we are finally starting to manage fisheries proactively which give the best chance at MSY (maximum sustainable yield). Sardine closures last few seasons as an example. An offshoot of proactive mnagment is bigger populations overall and that my friend gives sportfishermen a better shot of increased catches.
