  abstract = {{W}e studied the sexual maturity, batch fecundity and spawning season of the {S}kipjack {T}una {K}atsuwonus pelamis. {G}eneralized additive modelling was applied to assess the effect of demographic features on ovary growth. {D}uring 2009 and 2010, 673 females were caught on board a purse-seine fishing vessel in the western {I}ndian {O}cean. {F}ish were classified into different reproductive phases and this information was used to determine the size at maturity ({L}-50), the timing of spawning and the batch fecundity (n = 51). {T}he size at maturity ({L}-50) for females was estimated to be 39.9 cm. {T}he mean relative batch fecundity was 140 +/- 64 eggs g(-1) of fish. {S}pawning occurs during the monsoons and inter-monsoon seasons with peaks in the reproductive activity during the {N}orth-east and {S}outh-west monsoon events. {D}emographic differences were detected in the reproductive timing of the population and a large investment in gamete production was observed in fish with high hepatic condition and in their first spawning year.},
