Study of spawning season and spawning ground of soboor (Tenualosa ilisha, Ham. Bunch., 1822) during its migration in Khuzestan rivers
During 12 months of sampling, from 17 stations, 327 specimens of Soboor fish Tenualosa ilisha, including 120 females, 113 males and 86 immature were caught. Total length (TL) of the fishes was 120-500mm. Maximum diameters of soboor ova 0.795mm and the ova with diameter more than 0.7 mm released at one spawning round. Temporal and spatial distribution of ova diameter corresponding to GSI changes...

متن کاملSex-ratio, maturation and spawning of the Indian ilisha, ilisha melastoma (clupeiformes: pristigasteridae) in coastal waters of Pakistan (northern Arabian Sea)
Present study showed that the over-all sex-ratio deviated in favour of females in Ilisha melastoma. However, the sexratio 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. melastoma get matured is 14.9 cm in total length (11.5 cm in SL). Four mat...
