What is "white meat tuna" and why is it so significant

This and other tuna articles make a point that, in the US, only Albacore can be marketed as "white meat tuna". What exactly is "white meat tuna"? Is it just a US term for Albacore? Does it have a wider meaning outside the US than in it? Is there a particular reason why the term needs legal regulation? The articles as they are prompt more questions than answers, and need to be expanded for the benefit of those unfamiliar with American tuna politics. Wardog (talk) 09:51, 5 August 2011 (UTC)[reply]

Why is it so prized?

A paragraph on why albacore/"white" tuna is so prized would be useful.--Froglich (talk) 19:06, 29 October 2015 (UTC)[reply]

daily ration

I have removed a misleading statement "Due to so much energy being used by the constant movement, a typical tuna may eat one-quarter its own weight in food in one day" which was based on the following reference "All About A Tuna’s Life." Tuna Facts & Life Cycle. Bumble Bee Foods, LLC. Web. 25 Oct 2013. <http://www.bumblebee.com/about/seafood-school/life/> This suggests a 25% BW daily ration, which is clearly incorrect, given the daily ration of tunas studied to date varies inversely with body size from around 5% BW/day in small fish down to 1% BW/day, ( http://icesjms.oxfordjournals.org/content/66/4/720.full) ^[1],. If this is considered important information, I suggest a more realistic daily ration estimate of 1.0-1.1% BW/day should be indicated for adult albacore as used by Watanabe et al. (2004) ^[2] Professor Pelagic (talk) 08:01, 4 May 2016 (UTC)[reply]

Not that anyone asked, but I support this. Non-biologists are too prone to swallow unsupported assertions about large animals eating large fractions of their own mass daily. It might be true for some small shrew spp. or the like, but not large fish. JonRichfield (talk) 07:38, 1 November 2016 (UTC)[reply]
