Evidence of thermolabile sex determination in pejerrey

Journal of Fish Biology, 1996
Temperature regimes of 17 ± 1°C and 21 ±1°C early in development of pejerrey Odontesthes bonariensis produced nearly all females, whereas at 25 ± 1°C variable, sometimes male‐biased sex‐ratios were obtained. The critical period of thermolabile sex determination seemed to occur between 25 and 50 days post‐hatch (about 11 and 21 mm s.i.) at low ...

Progenitor Radial Cells and Neurogenesis in Pejerrey Fish Forebrain

Brain, Behavior and Evolution, 2010
The central nervous system of adult teleost fish is peculiar because of the following features: (1) the persistence of radial glial cells, (2) an important neurogenic activity and (3) a high aromatase expression by radial cells. In this study, the proliferative zones of the forebrain were described using bromodeoxyuridine (BrdU) treatment in the brain ...

Dmrt1 expression analysis during spermatogenesis in pejerrey, Odontesthes bonariensis

Fish Physiology and Biochemistry, 2006
Dmrt1, a putative transcription factor with a DM-binding motif (called the DM domain), is generally considered to be exclusively expressed in testicular tissue, except in some teleost species where it has also been demonstrated to be expressed at the ovary.

Sex differentiation and hormonal feminization in pejerrey Odontesthes bonariensis

Aquaculture, 1996
Abstract An investigation was conducted on the histological process of gonadal sex differentiation and the suitability of steroid hormone administration for sex control in pejerrey, Odontesthes bonariensis . Light histological examination of the gonads of larvae and juvenile fish revealed that the primordial gonads were already formed at hatching ...
