Abstract
Hermaphroditism characterized by the presence of oocytes in the testes is described in the blue tilapia, Oreochromis aureus, for the first time. Testis-ova were observed in three of 24 spawning males exhibiting otherwise normal male morphology. The testis-ova appeared non-vitellogenic and lacked a follicle cell layer. It is speculated that the testis-ova did not become vitellogenic due to their association with Sertoli cells and the hormonal environment of the male.
