Studies on the oogonial cycle in Puntius ticto (Ham.) I. Formation of primary oocytes.
Histologically, the ovary of Puntius ticto (Ham.) is covered with three layers, namely peritoneum, tunica albuginea and germinal epithelium. The last two give rise to the ovigerous nests in the ovocoel. The new crop of oocytes is either derived from the germ cells present in the ovigerous nests, or from the epithelium of the outer wall of the ovary, or from the epithelium of the ovigerous folds.
