Transmission electron microscope (H-300) was used to do the observation. The proximal pars distalis (PPD) is mainly composed of growth hormone (GH) cells, thyrotrophs (TSH) cells and gonadotrophic hormone (GTH) cells. The observations on the annual cycle of the structure of PPD show that the GH cells have high activities during the oogenesis; the TSH cells show hyperactivity synchronous with the gonadotrophs, indicating that TSH may play an important role in teleost ovulation control. The ultrastructural features of the GTH, TSH and GH cells are discussed herein, including the released way the secretory granules take from the secreting cells.</em></p><p class='subject'><strong>关 键
