“…Droller and Roth (1966) reported that the early stages of oocytes of Lebistes reticulatus are characterized by the presence of proliferated Golgi apparatus and rough endoplasmic reticulum. Moreover, Cárdenas et al (2008) and Abdel-Aziz et al (2012) stated that the ooplasm of the oocytes of Chirostoma humboldtianum and Scarus ferrugineus, respectively, at the primary growth stage, possess numerous free ribosomes, rough endoplasmic reticulum and mitochondria. Kowtal (1967) reported that the spawning of Mugil cephalus in the Chilka Lake occurs from October to December.…”

Liza carinata is considered as a common and economically important Mugilidae fish of the Red Sea. Knowledge of the gonadal cycle in fishes has a great importance in the successful management of fisheries. The present study was undertaken to gain more information about the morphological, histological and ultrastructural aspects of the ovaries of L. carinata during the different seasons of its reproductive cycle in the Suez Bay. The maturity stages of the ovaries of L. carinata can be classified into four stages, namely: the early post-spawning, late post-spawning, pre-spawning and spawning stages. Besides, L. carinata spawns from late September to late December. Moreover, the oogenesis of L. carinata is divided into seven stages. These stages are the oogonia, chromatin-nucleolar, early peri-nucleolar, late peri-nucleolar, vacuolated, early yolk globular and late yolk globular stages. In addition, the ovaries also contain the post-ovulatory structures and atretic follicles. The former are formed of the hypertrophied follicular cells after the discharge of the mature ovum, while the latter are formed as a result of the sudden cease growth of the oocytes. The present observations may help in understanding the strategy of reproduction of L. carinata in the Suez Bay that may help in its aquaculture.
