Time‐ and temperature‐dependent appearance of vitellogenin in Golgi vesicles and serum after estrogen treatment of salmon ( Salmo salar)
Abstract The temperature‐dependent time course of vitellogenesis was examined in presmolt salmon ( Salmo salar ). Fishes were kept at 8°C or 16°C and injected with 17‐β‐estradiol. The rise in translation activity in liver preceeded that of RNA. At both acclimation temperatures, vitellogenin appeared...
