Odontesthes regia

Odontesthes regia (Humboldt, 1833) (Teleostei: Atheriniformes) belongs to the Atherinopsidae family and is locally known as “pejerrey” or “pejerrey marino,” and internationally as “sea silverside.” This is an epipelagic species distributed from the north Pacific coast of Peru to the Aysen region, in Chile (Dyer 2000). The species has great economic importance as a fresh staple food (Froese & Pauly 2005). Although the family Atherinopsidae includes 104 species (13 genera), only 17 species have been cytogenetically studied to date (Table 1), demonstrating that cytogenetic studies in this group are still scarce. http://www.scielo.cl/scielo.php?pid=S0718-19572006000100008&script=sci_arttext
