Sushi
How is it eaten? is the kind in sushi or in cans or you get as a steak... —Preceding unsigned comment added by 80.86.74.23 (talk) 22:42, 23 August 2009 (UTC)


 * You eat it as sushi, or in a steak. However, this species is critically endangered and there aren't many of them left. Qwertyxp2000 (talk) 05:53, 15 May 2015 (UTC)
 * To eat bluefin tuna raw it needs to be considered "Sushi Grade". To make a bluefin tuna sushi grade, it would have to be processed in a certain way like bleeding the fish, properly killing the fish, gill and gutting the fish and putting the fish in a blast freezer. These crucial steps ensures the product to be of high quality and safe for consuming bluefin tuna raw, such sushi. RKhalaf1999 (talk) 01:00, 26 April 2022 (UTC)

Gulf of Mexico Oil Spill.
The newspapers say that the area where the 2010 GoM spill took place is one of the Bluefin;s breedig grounds. —Preceding unsigned comment added by 24.17.118.100 (talk) 09:48, 4 May 2010 (UTC)


 * Its was the Atlantic Bluefin Tuna that was impacted during the 2010 GoM spill, not the Southern Bluefin Tuna. They are both tunas but deferent species of tuna.

Recommendation to merge some of the sections with Tuna page.
There is a lot of overlap between the Thermoregulation, Conservation Status, Environmental Issues, and Farming sections for the Pacific bluefin tuna, Northern bluefin tuna, and Southern bluefin tuna. Some of this information is also repeated on the Tuna page. Since most of the information is general and not specifically related to the individual species I propose that this information should be discussed at the genus level (i.e. merge with the Tuna page). An alternate proposal might be to create new pages geared to the specific topics like Thermoregulation in Tuna and Conservation Status, Environmental Issues, and Farming of Bluefin Tuna.


 * Note: I have copied and pasted this talking point on each of the pages listed above. XXVII (talk) 07:46, 9 May 2010 (UTC)


 * There is some merit in rationalizing the various subtopics, but Pacific, Northern and Southern bluefin tuna also need their own articles, with much expanded sections on their industrial fishing. --Epipelagic (talk) 08:58, 9 May 2010 (UTC)


 * Agreed. Clarification: The proposal is to rationalize the various subtopics, and merge repeat information in a logical manner. The Pacific, Northern, and Southern bluefin tuna need their own articles, and these articles should be expanded.XXVII (talk) 00:13, 16 May 2010 (UTC)
 * disagree; I don't see a way we can collapse several complete articles into one. At least not without tossing most of the data.--Marhawkman (talk) 19:36, 7 October 2010 (UTC)

Fish are not flash frozen and then put on Tokyo planes, airfreighted fish are sent fresh chilled 0 - 5 degrees C.

Orphaned references in Southern bluefin tuna
I check pages listed in Category:Pages with incorrect ref formatting to try to fix reference errors. One of the things I do is look for content for orphaned references in wikilinked articles. I have found content for some of Southern bluefin tuna's orphans, the problem is that I found more than one version. I can't determine which (if any) is correct for this article, so I am asking for a sentient editor to look it over and copy the correct ref content into this article.

Reference named "Clark": From Great South Australian Coastal Upwelling System: Ian D. Clark, pp17-22, ''Scars on the Landscape. A Register of Massacre sites in Western Victoria 1803-1859'', Aboriginal Studies Press, 1995 ISBN 0-85575-281-5 Excerpt also published on Museum Victoria website, accessed 26 November 2008 From List of marine animals of the Cape Peninsula and False Bay: Clark A. & Courtman-Stock J. 1976. The Echinoderms of South Africa British Museum (Natural History) London ISBN 0-565-00776-9 

I apologize if any of the above are effectively identical; I am just a simple computer program, so I can't determine whether minor differences are significant or not. AnomieBOT ⚡ 05:59, 3 December 2013 (UTC)

Rete mirabile: Incorrect original research
The above statement is 100% false, unsubstantiated, and constitutes original research. The entire point of the counter-current heat exchange that exists in the rete mirabile ("wonderful net") of all tunas is that the heart and gills operate at a temperature close to the ambient temperature – the temperature of the surrounding ocean. Take the following passage, which, although written in an article specific to the albacore tuna, describes the process that exists in all tunas:

So in other words, the cool, oxygenated blood in the arteries is heated from ambient temperature on its way from the heart to the muscles. By the way, when they say "nearly all of the metabolic heat", they're not kidding, because the heat exchange in the rete is extremely efficient in tunas – in bluefin tuna, for example, that heat exchange approaches 99% efficiency.

As an aside, I'd point out that many species utilize a rete mirabile for many different purposes. For example, in slow-moving sloths and lorises, which may cling to or hang from a tree branch for what seems like an eternity, they use the rete to lower their limb temperature, and therefore lower the metabolic requirement for oxygen and nutrients in the tissues of that limb. — Groll &tau;ech  ( talk ) 21:36, 10 February 2014 (UTC)


 * I have come across an additional reference that supports my previous assertion in this dispute, stating:


 * Given this new reference, I will:
 * add it to the article;
 * correct the disputed statement; and
 * remove the dispute template.

Why was the undue tag placed on this article?
The tag was placed on this article more than 4 years ago, but I don't see any other evidence of controversy here. Which part of the article does this tag apply to? Jarble (talk) 01:54, 4 February 2015 (UTC)

Source for article expansion
Here's a recent publication which may prove useful in updating/expanding this article. https://www.hakaimagazine.com/article-long/swimming-tuna --Danimations (talk) 05:43, 19 October 2016 (UTC)


 * Thank you very much for the article, swimming with tuna has always been my curiosity. In Southern California we have tuna pens and I would always see them when I go out to sea. I wonder if they would allow visitors to come check out the tuna pens up close. RKhalaf1999 (talk) 01:15, 26 April 2022 (UTC)

Evaluation

 * On the first read, this article stated a lot of facts and charts giving the reader a neutral perspective of the Southern bluefin tuna and it covers all the different aspects of associated with this marine life. The chart in the Commercial Fishing section is biased based on the fact that it does not show the data from a distant past and it only shows a window of 50 year history. There would be a better understanding of the data if there were data collected for 100 years. It is possible that between 1969 to 1981 the fishing industry had a booming period and then after went back to its normal level.


 * The Commercial Fishing section there are no citations, there are plenty of stats and a chart presented but no citation to back it up.


 * I also tried about 20 links in the Reference section and out of this 20, 6 links were broken and gave me a 404 error and one link would give you a blank page with the company logo and nothing else which IF you would like on it it would redirect you to the home page. Overall the references need to be updated to give legitimacy to this page. I have included some of the broken links below.
