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.

Cooling of pejerrey Odontesthes bonariensis (Teleostei, Atherinidae) embryos at sub-zero temperatures

Theriogenology, 2020
Pejerrey fish (Odontesthes bonariensis) is a seasonal multiple spawner with great economic importance and an adequate species for Aquaculture. For these reasons, it is necessary to apply biotechnologies to optimize its reproduction in captivity. In this context, the aim of this work was to develop a cooling protocol for pejerrey embryos at sub-zero ...

Triploidy Induction in an Atherinid Fish, the Pejerrey (Odontesthes bonariensis)

The Progressive Fish-Culturist, 1993
Abstract Experiments were conducted on triploidy induction and effects of triploidy on growth and survival of embryos, larvae, and juveniles of pejerrey, a freshwater atherinid fish. Eighty minutes of cold shock (0.5–0.8°C) starting 6 min after egg activation at 18.5°C consistently induced 100% triploidy, as assessed by chromosome counting of juvenile ...

Role of apoptosis in temperature-dependent sex determination of pejerrey Odontesthes bonariensis

2008
This report outlines the findings of a preliminary study on the possibility that apoptosis (programmed cell death) plays a role in gonadal sex differentiation of pejerrey Odontesthes bonariensis (Pisces, Atherinopsidae), a “differentiated” gonochorist fish with a striking degree of temperature-dependent sex determination (TSD).

Aspectos históricos e importancia regional del pejerrey bonaerense

2001
Como señalaran Lahille (1929) y Muñoz Goyanas (1988) el origen de la denominación popular del género Atherina deriva del vocablo medieval "pejerrey" constituido por dos palabras peje-reí o pejerey (pez de reyes). Este témino era aplicado en Europa a una especie única de gran valor culinario reiteradamente alabada por los monarcas españoles.
