  abstract = {{T}he lipid composition of somatic and reproductive tissues was determined for female skipjack tuna {K}atsuwonus pelamis caught in the western {I}ndian {O}cean between latitude 10° {N} and 20° {S} and longitude 40° and 70° {E}. {T}he highest total lipid ({TL}) contents were in the liver and gonads, with white muscle levels approximately three-fold lower. {T}hree lipid classes dominated: triacylglycerols ({TAG}), sterol esters and wax esters ({SE}-{WE}) and phospholipids ({PL}). {C}ollectively, these accounted for between 70 and 80% of {TL}s. {C}hanges in lipid concentrations were evaluated over the maturation cycle. {I}mmature fish had the lowest gonad and liver {TL} levels; concentrations of {TL}, {TAG}, {SE}-{WE} and {PL} accumulated from immature to mature (spawning-capable) phase, reflecting sustained vitellogenic activity of the liver and a transfer of lipids to developing oocytes from the onset of vitellogenesis. {G}onado-somatic and hepato-somatic indices were positively correlated with each other and positively related to {TL} in the gonads and liver. {F}ulton's condition index and lipid concentrations in muscle did not vary significantly over the maturation cycle; fat content in the main storage tissues was undepleted as the ovary developed. {H}ence, {K}. pelamis apparently supports reproduction directly from food intake over the breeding season. {I}n the gonads, reserve lipids ({SE}-{WE} and {TAG}) and sterols were related to batch fecundity but this was not the case for somatic and hepatic tissues. {T}hese results suggest that {K}. pelamis utilizes an income breeding strategy.},
