Pejerrey Odontesthes bonariensis

2017
Pejerrey Odontesthes bonariensis was reared in the recirculation system for 1 year. The system consisted of two particle-trap equipped octagonal tanks (0.75 m3) for the rapid collection of feces and uneaten feed, a mechanical filter, a UV unit, a biological filter which provided nitrification, and a hollow-fiber oxygen injection system.

Atrazine alters early sexual development of the South American silverside, Odontesthes bonariensis

Aquatic Toxicology, 2023
Atrazine (ATZ) is a frequent contaminant in freshwater ecosystems within agricultural regions. The capacity of this herbicide to interfere with the vertebrate endocrine system is broadly recognized, but the mechanisms and responses usually differ among species. In this study, ATZ effects on hypothalamus-pituitary-gonadal (HPG) axis key genes expression

Benzocaine and clove oil as anesthetics for pejerrey (Odontesthes bonariensis) fingerlings [PDF]

Arquivo Brasileiro De Medicina Veterinaria E Zootecnia, 2013
Pejerrey (Odontesthes bonariensis) is a native species from Rio Grande do Sul, Uruguay and Argentina where it is of great economic importance for artisanal fishing. One difficulty in laboratory research with pejerrey is related to its sensitivity, as it presents higher basal cortisol levels than other freshwater species.

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 ...

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.

Heat-induced Germ Cell Deficiency in the Teleosts Odontesthes bonariensis and Patagonina hatcheri

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 1998
Pathological 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.

PCBs and Organochlorines in Tissues of Silverside ( Odontesthes bonariensis ) from a Coastal Lagoon in Argentina

Archives of Environmental Contamination and Toxicology, 2000
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.

Molecular cloning, expression and immunological characterization of pejerrey (Odontesthes bonariensis) growth hormone

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2006
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 ...

Cytogenetical characterization of Odontesthes bonariensis (Pisces, Atherinidae), an Argentine species introduced in Italy

Genetica, 1988
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 ...
