  abstract = {{T}otal lipid content and lipid class composition were analyzed in gonads, liver and white muscle of yellowfin tuna ({T}hurtnus albacares) throughout ovary development to understand its reproductive allocation strategy and to assess the relation between female condition and reproduction. {A} total of 112 females were collected onboard purse-seiner in the {W}estern {I}ndian {O}cean from {J}anuary to {M}arch 2009, from {J}une to {J}uly 2009, and from {A}pril to {M}ay 2010. {G}onads were characterized by highly variable total lipid contents ranging from 5 to 27 mu g mg(-1) of wet weight (ww) with a predominance of neutral lipids, mainly triacylglycerols ({TAG}) and sterol- and wax-esters. {T}he different lipid classes in gonads described an accumulative pattern through the maturity process from immature to hydration phase. {T}otal lipid content in liver varied from 10 to 21 mu g mg(-1) ww, and serves as fuel for yellowfin tuna reproduction. {TAG} and phospholipid deposits became depleted as the ovary developed, suggesting a transfer of lipids directly from liver to the oocytes during vitellogenesis. {I}n contrast, muscle total lipid content was low and constant throughout ovarian development (2.5-6 mu g mg(-1) ww). {H}ence, yellowfin tuna can be defined as an income-capital breeder species for which the cost of reproduction depends mainly on concurrent energy income from feeding and only little on stored lipids. {B}esides, no significant relationship between gonad lipid composition and fecundity was found in females able to spawn. {F}inally, the influence of yellowfin tuna aggregation behaviour on reproductive female condition has been investigated: gonad total lipid contents were higher in females caught in free-swimming schools than in females caught under fish aggregating devices ({FAD}s). {H}owever, these results did not clarify whether the influence of {FAD}s on associated yellowfin tuna affects their reproductive capacity.},
