Considérations sur la croissance ovocytaire chez les poissons à ovogenèse synchrone et asynchrone.

BELGIAN JOURNAL OF ZOOLOGY, 121(1):87-98.

In fish, three patterns of oocyte growth were determined by a dynamic approach of ovogenesis: the synchronous, group-synchronous and asynchronous ovary. The first group includes the monospawner fishes in which the ovary contains only vacuole free oocyte during the start of recrudescence. During the spawning season, the histogram of oocyte size contains only two classes corresponding to the vacuole free and globule stage oocytes. The second group is characterized by the presence of three classes in the histogram of oocyte size: vacuole free, yolk vesicle and yolk globule stage oocytes. The third group includes the multi spawner fishes in which ovaries contain different oocyte stages without predominance of one class. This paper briefly describes the maturity of different species from these three groups in terms of variations of gonadosomatic index, composition of ovary and characteristic of oocyte growth during sexual cycle.
