Talk:Atlantic bluefin tuna

message: === Typical size? ===
The article says:
The typical size is 2 m (6.6 ft) at about 500 kg (1,100 lb).
Really? Can someone who is expert in this area double check that? I appreciate that Northern bluefin tuna can grow that big, but surely that is not the typical size. That's enormous: half a metric tonne, 0.55 tons, or 78 stone. Other sources I have looked at, such as this, suggest much smaller. --DZR 19:03, 30 November 2006 (UTC)
replies: text: This site says "The bluefin tuna is one of the largest of the tunas" and "Bluefin commonly attain a size of 78 inches (200 cm)." The 7 kg. figure for typical weight must be a typo, as the same site describes the young as "up to a size of 90 to 130 lbs. (40 to 80 kg)." -- Donald Albury 23:53, 4 December 2006 (UTC)
replies: text: Wouldn't really be sure about the weight, but the length is quite average. Yellowfin over here average at around the same size generally. Shrumster 15:00, 5 August 2007 (UTC)

text: I fish bluefin tuna off of northlake, PEI in Canada. We just wrapped up part of the season(they have the quota partially split this year, 40 metric tons in august and the rest in September, I'm not sure how much though) and if you can get one that weighs over 800lbs not dressed("dressing" is when the head, tail, and organs are removed, it is then weighed again, the dress weight is then given. When its payed for at an auction(a #of$/lb) they pay for the dressed weight) then you've got a big fish, a nice sized fish. A lot of the oens that come in are like 300-500lbs round(not dressed). However, years ago(1970s and such) the average size you have posted here would be very close. They have gotten a lot smaller. So the average weight would have changed over the years wouldnt it? 142.176.58.216 14:03, 8 August 2007 (UTC)

thread_title:  Typical size? 

message: The line "and it is thus better to avoid consumption of bluefin tuna until stocks recover." is inappropriate for an encyclopedia article. Maybe you could find some source that offers this advice and comment on that.24.136.6.69 (talk) 02:08, 10 March 2008 (UTC)
thread_title:  Consumer Advice/Advocacy 

message: What's the sigfigance of this? is it unique to this species? otherwise why is it included, most articles on fish don't contain specific details on their anatomy.unsigned
:This is a notable ability that this fish has. Most other fish do not have this capability. A better explanation is provided on the Pacific bluefin tuna page.   XXVII (talk) 07:28, 9 May 2010 (UTC)
thread_title:  Thermoregulation 

message: 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)
replies: text: 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) 00:14, 16 May 2010 (UTC)

thread_title:  News source 

message: The article seems to be several years out of date.  It needs to be brought up to the present with information about whether the population is growing, declining, considered endangered and if so by whom, etc.  Vaughan Pratt (talk) 07:16, 29 September 2015 (UTC)
replies: text:  There is a large amount of updated literature on these fish that should be added to this page. ICCAT has published two updated reports since the one referenced in this article. As they are such a threatened and heavily fished fish, this information is very relevant to a number of sections on this page. Andleon0325 (talk) 12:42, 22 September 2020 (UTC)
replies: text: The overall article tone still seems dominated by the catastrophism of 20 years ago when it became widely understood that tuna were being severely overfished almost everywhere. While conservation successes since have been patchy, bluefin numbers have widely recovered, particularly in the eastern Atlantic and Mediterranean. This is mentioned briefly in the article, but it seems like an afterthought. See this Guardian piece. --Ef80 (talk) 14:29, 9 February 2024 (UTC)

I want to challenge the reference that says they are near threatened, because recent studies show that stocks have steadily increased.
