Gonad Histology And Spawning Pattern Of The White Grouper (Epinephelus Aeneus) From İskenderun Bay (Turkey), Mahmut Ali̇ Gökçe, İbrahi̇m Cengi̇zler, A. Argun Özak

Turkish Journal of Veterinary & Animal Sciences

The gonad histology and spawning pattern of the white grouper (Epinephelus aeneus) were determined from fish sampled from commercial catches. Histological, microscopic and macroscopic techniques were used to examine the ovaries of E. aeneus. A six stage maturity scale based on morphology was proposed to classify ovarian development. The results showed that the white grouper has an asynchronous mode of ovarian development, and the histological study of oocyte development in the white grouper indicated that two types of inclusion, first lipid and then protein, are formed during vitellogenesis. Towards maturation, protein granules and lipid droplets increased in size and number …
