Heat-induced Germ Cell Deficiency in the Teleosts Odontesthes bonariensis and Patagonina hatcheri
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 1998Pathological or experimental elevation of testicular temperature is known to trigger degeneration and disappearance of germ cells in scrotal mammals. In contrast, there are no reports of heat-induced germ cell deficiency in males of non-scrotal mammals and other vertebrate taxa, nor in females of any species.

A freshwater fish species, silverside (Odontesthes bonariensis) from Mar Chiquita coastal lagoon, Argentina, was analyzed for concentrations of several organochlorine pesticides (OCs) and polychlorinated biphenyls (PCBs) in liver, gonads, mesenteric fat and muscle, and the contents of the digestive tract over several stages of sexual maturation.

Growth hormone is an essential polypeptide required for normal growth and development of vertebrates. The pejerrey fish, Odontesthes bonariensis, is a South American atherinid freshwater fish considered as a promising species for aquaculture. Although growth hormone has been characterized in a number of fish, there are no published data on the ...

Giemsa and Ag-staining techniques and C-banding were performed on cytological preparations of 22 specimens of silversides (Odontesthes bonariensis) in order to extend the karyological knowledge on the family Atherinidae, to contribute cytotaxonomically to the systematics of the species and to identify possible cytogenetical markers of the introduced ...

Triploidy Induction in an Atherinid Fish, the Pejerrey (Odontesthes bonariensis)
The Progressive Fish-Culturist, 1993Abstract 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
2008This 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).
