 note = {application/pdf, This paper describes the differentiation and development of systemic organs and tissues of larval and juvenile red sea bream, Pagrus major. They were from 0 to 50 days old and reared in Shizuoka Prefectural Fish Farming Center from 1987 to 1988. The larvae that hatched individually formed an
esophageal cavity, rudimentary visceral organs, an intestine, an rudimentary heart, eyes with the lens and germinal retina, nasal neuromasts, telencephalon and optic lobes of the brain, spinal cord, cavities
of the inner ears, notochord of the mesh work, lateral musculature consisting of myomeres, the epidermis containing alarm substance cells and membranous fins. The rectum, head kidney with nephron and henmtopoietic cells, free neuromasts of the skin, and rudimentary gill arches developed on day 1. Pancreatic cells, hepatic cells, a rudimentary swim-bladder and sensory papillae of inner ears were seen, and the retina of eyes showed differentiation on day 2. Granular and molecular layers in
the brain such as telencephalon, optic lobes and medulla oblongata began to develop on day 3.   In these fish, gill filaments, a swim-bladder with a pneumatic duct, bulbus arteriosus, ventricle, auricle and sinus venosus, pectoral fins also shaped up. The retina of eyes differentiated well on day 4. Erythrocyte production occurred in the head kidney and on the endothelia of heart and sinus venosus when hypothalamic saccus rudiment shaped up on day 5. Thyroid follicles and a splenic rudiment shaped up on day 6.   Primitive gas secreting cells differentiated and rate mirabile formed in the swim-bladder, and blood circulation began to obvious on day 7. Pharyngeal teeth and a hypophyseal rudiment developed on day 11. Gill lamellae differentiated on day 12.  Vertebral ganglions and pseudobranch formed, and a pneumatic duct closed on day 14.  The thymus containing large mononuclear cells and cartilaginous hypurals formed, when the lateral musculature, heart and head kidney developed on day 17. Cartilaginous hemal and neural spines began to grow as well as primitive lepidotrichiae growing in pectoral and caudal fins on day 18. In 21-day-old larvae, their hypophysis differentiated into adeno- and neuroparts. Pterygiophore and muscle for the dorsal and anal fins, and renal tubules of the anterior kidney developed. The cerebellum mostly composed of a granular layer. Also, splenic arteries, Stannius corpuscles in the posterior kidney and rudimentary gill-raker shaped up around day 23 to 24. Their
brain, inner ears, noses, and gills began to develop. Gastric gland cells and oval gland cells of the swim-bladder formed on day 26.   Pyloric caeca and interrenal cells on a renal vein formed in 29-day-old
juveniles. When thymus produced small lymphocytes and a thickened chorda sheath began to make articulation, the spines and lepidotrichiae grew long in the dorsal and anal fins on day 30. Scale sacs containing a thin scale appeared in the dermis, and splenic sheathed arteries and pulps differentiated well on day 31. Stomach exhibited gastric gland cells producing zymogen granules and nephron differ-
entiated in the posterior kidney on day 33. Taste buds increased in number in the mouth and vertebrae accompanying the periosteum in the articular region shaped up on day 36. Stomach was lined by mucosa and the liver developed into hepatopancreas on day 37. Then, systemic organs and tissues be-
came to develop well, exhibiting an increase in hematopoietic cells in the anterior kidney on day 47 and in the posterior kidney on day 50.},
