Social control of primary sex differentiation in the Midas cichlid.
Sexual differentiation in teleost fishes is characteristically labile. The most dramatic form of sexual lability is postmaturational sex change, which is common among teleosts although rare or absent in other vertebrate taxa. In many cases this process is regulated by social cues, particularly dominance interactions. Here we show that in the Midas cichlid, Cichlasoma citrinellum, these same sor...
متن کاملSex differentiation in goat fetus
Reproduction in domestic animals, as a major source of food and other products for human, has greatimportance and study of related subjects including sex differentiation and gonadogenesis during fetal life can solve many questions on normal development and various disorders of urogenital system.

متن کاملSodium and water balance in the cichlid teleost, Tilapia mossambica.
The ability of some fishes to live in both sea water and fresh water has attracted a great deal of interest. Many euryhaline fishes are difficult to rear in laboratory conditions ; some do not survive in completely fresh water, and migratory fishes are often euryhaline for only limited periods during their life-history. Species of the genus Tilapia have none of these disadvantages; they are eas...
متن کاملHistopathological changes in gills , liver and kidney of fresh water fish , Tilapia zillii , exposed to aluminum
The present study was carried out to study gills, liver and kidney histopathology in the freshwater fish, Tilapia zillii which exposed to three levels of aluminum (25, 50, and 100 μg/L) for 96 hour in acidic soft water (pH 6.0). Several histopathological changes were observed in fish organs would serve useful purpose in evaluating the toxic effects of aluminum. Histopathological changes in gill...
متن کاملAromatase plays a key role during normal and temperature-induced sex differentiation of tilapia Oreochromis niloticus.
In the tilapia Oreochromis niloticus, sex is determined genetically (GSD), by temperature (TSD) or by temperature/genotype interactions. Functional masculinization can be achieved by applying high rearing temperatures during a critical period of sex differentiation. Estrogens play an important role in female differentiation of non-mammalian vertebrates. The involvement of aromatase, was assesse...
