| description | In order to study the initial formation of the vitelline envelope and the appearance of vitellogenin in oocytes of rainbow trout, females were sampled monthly from 19 to 5 mo before ovulation. lmmunohistochemistry revealed that the formation of the vitelline envelope starts when the oocytes reach a diameter of about 450 μm. Oocytes of this size were first found in females sampled a year before ovulation at the time when plasma levels of estradiol‐17β increased from 0.2 to 0.6 ng/ml. An antiserum directed against vitellogenin crossreacted with small vesicles (around 2 μm) present just inside the oolemma, when the oocytes reached a diameter of 600 μm. This was interpreted as an active uptake of vitellogenin. Oocytes of this size were first found in females sampled 9 mo before ovulation at the time when estradiol 17β levels increased from 0.6 to 1.0 ng/ml and the gonadal somatic index was doubled. Oocytes with a diameter of 600 μm had an immunoreactive vitelline envelope with a thickness of about 3 μm. It is apparent that the initial formation of the vitelline envelope starts before the active uptake of vitellogenin and that the low previtellogenic plasma levels of estradiol‐17β observed in females are of physiological significance. © 1994 Wiley‐Liss, Inc. |
