|Title:||Sex-ratio, maturation and spawning of the Indian ilisha, <i>ilisha melastoma</i> (clupeiformes: pristigasteridae) in coastal waters of Pakistan (northern Arabian Sea)|
|Abstract:||Present study showed that the over-all sex-ratio deviated in favour of females in <i style="">Ilisha melastoma</i>. However, the sex-ratio was approximately 1:1 in certain months while in others it was in favor of females. Similarly the sex-ratio deviated from 1:1 ratio in different size-classes. Minimum size at which the specimens of <i style="">I.</i><i> melastoma </i>get matured is<i> </i>14.9 cm in total length (11.5 cm in SL). Four maturation stages of ovaries, namely, immature, ripening, ripe and spent/recovering were recognized in <i style="">I.</i><i> melastoma</i>. Two peaks of spawning were observed in this species, the major peak was from February to May and the minor peak appeared in August to November.|
