Talk:Bigeye tuna

Update

I have updated the page with information on the vertical movement behavior and diet behavior of the bigeye tuna. — Preceding unsigned comment added by Junsu.shinn (talk • contribs) 02:57, 25 October 2013 (UTC)

• There was quite a lot of redundancy in the behavior section that I tried to fix by rearranging sentences and cutting out repeated phrases. More specific comments:
  • Move range and habitat information to the introduction, it's short enough not to need its own section
  • Don't use the pronoun "we"
  • Integrate the Diet and feeding subsections so they're one subsection under behavior (or separate from behavior)
  • Do you mean " yellowfin tuna will not move to depths that differ in temperature by MORE than 8 °C from the surface temperature"?
  • The sentence "The bigeye is not as sensitive to the gradient difference as the yellowfin when it comes to temperature differences in different depths" is ambiguous, are you talking about oxygen availability or temperature? It could be clarified if it was changed to "Bigeye tuna are not as sensitive to temperature/oxygen differences as yellowfin tuna"
  • The phrase in vertical movement "but it is still required in order to survive" seems not fully related to the rest of the passage
  • Thunnus is a genus, not a family; Scombridae is the family, which one are you referring to? (vertical movement section)
  • Are there other physiological reasons besides oxygen binding for why bigeye tuna can go to greater depths than yellowfin tuna? If there are, at least mention them

• While I was searching for Bigeye tuna on Google scholar, I found some interesting facts. I thought that you could add them into the page. 1) Kume, Susumu and Joseph, James (1966) Size composition, growth and sexual maturity of bigeye tuna, Thunnus obesus (Lowe), from the Japanese long-line fishery in the Eastern Pacific Ocean. Inter-American Tropical Tuna Commission Bulletin, 11(2), pp. 45-100. (relationship between environmental temperature and sexual maturity is quite interesting) 2) Maury (2005) How to model the size-dependent vertical behavior of bigeye tuna in its environment. Col. Vol. Sci. Pap. ICCAT 57(2):115-126. (This suggests that size might be another variable in describing vertical behavior of bigeye tuna) — Preceding unsigned comment added by Hami910311 (talk • contribs) 22:32, 31 October 2013 (UTC)
