Glow-light tetra, Hemigrammus erythrozonus is a teleost belonging to Characidae. The natural habitate of this fish is
the wild in the Essequibo river, Guyana and South America. The oogenesis of glow-light tetra was investigated by light
microscopy to compare with those of other families.
A pair of ovary was located between swim bladder and intestines. The ovary was of white color and ellipsoidal shape
with the major axis 11 mm and the minor axis 4 mm.
Cytoplasm of oogonia was basophilic and many nucleoli were located at inside of nuclear membrane. In primary
oocytes, yolk vesicles were distributed only in the marginal area and egg envelope was not formed on the outside of an
egg. In secondary oocytes, the egg envelope was formed and yolk vesicles in the cytoplasm were increased than the earlier
stage. The amount of basophilic substance was decreased. In case of matured egg, thickness of egg envelope and size of
egg were increased, basophilic substance was distributed in only around the egg envelope. The yolk vesicles were changed
to yolk mass in accordance with development.
In conclusion, the oogenesis of glow-light tetra, Hemigrammus erythrozonus was characterized by the increase in cell
size, the formation and accumulation of yolk, and the decrease of basophilia a in the cytoplasm. The oogenesis of glowlight
tetra seems to share common patterns in Characidae, teleost and have a similar pattern with other teleost.
