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.
