ABSTRACT
Ihe sequellce l~! oocyte matllratioll ill A4ugil seheli .frOlJl the Suez Bay is

histologically divided illto lIille staxes, these !listoloXical ident{[ied staxes are

related to Sel’elll110lphologicai staxes. ]l,e histology l!!the ovaries l!fA4uJtii

seheli is exami11ed to give a picture ofthe reproductil’e cycle ofthis .\pecies.

Seven developmelltal stages are described in details. Oocyte’s maturation was

divided into nille stages; chrolJlotil1, eody peril1ucleolus, late perinue/eolus,

yolk vesicle, primaly yolk, seclJl1dmy yolk. tertimy yolk, mature and rip stage.

Oogel1ic development il1 Mugil seheli is belongillg to a.~Yl1chronous type. 111

this type the spaw11i11g season was fou11d to be IOl1g and extending from

Novemher to March.
