Seasonal histological and macroscopic changes in the gonads ofCheimerius nufar(Ehrenberg, 1820) (Sparidae: Pisces)

“…Although most authors agree on the basic characteristics incorporated into such a system, schemes used are often too brief (Kuo, Nash & Shehadeh 1974;Hilge 1975Hilge ,1977, or incomplete (Abraham 1963;Abraham et al 1966), or exhibit too much detail (Yamamoto 1956a;Braekevelt & McMillan 1967;Van der Horst 1976). The classification system implemented in this study is based on the oogenetic and vitellogenetic changes as described by Yamamoto (l956a, b, c, 1957), Braekevelt & McMillan (1967) and Van der Horst (1976).…”

Circadian responses of teleostean oocytes to gonadotropins and prostaglandins determined by cyclic AMP concentration

“…The (Fontaine et al, 1970 ;Menon and Smith, 1971 ;Fontaine et a/., 1972 (Tsafriri et al, 1972a, b), luteinization (Channing, 1970 ;Kolena and Channing, 1971), ovarian steroidogenesis (Pharrissetof., 1968 ;Speroff and Ramwell,1970 ;and (normal light cycle) ; the other timed the onset of the light phase at 6 p.m., and therefore reversed the conditions (reversed light cycle). At the end of the acclimation period, the oocytes developed beyond a mean diameter of 600 g, at which stage they are known to be effectively responsive to SG-G100 (Kuo et al, 1974). Samples of oocytes were withdrawn through a polyethylene cannula from every fish at 3-hr time intervals throughout a 24-hr period.…”
