The role of amides in seminal cryopreservation of wild silverside, Odontesthes bonariensis
Cryobiology, 2016Amides were tested as internal cryoprotectants for the preservation of wild silverside (Odontesthes bonariensis) sperm. The semen was diluted in modified Mounib's medium and cryopreserved by adding 2, 5, 8 or 11% of dimethyl acetamide (DMA), dimethyl formamide (DMF) or methyl formamide (MF).

Reproduction in Odontesthes bonariensis (Atherinidae: Pisces) from north-western Argentina
Journal of Applied Ichthyology, 2002The spawning biology of silver fish, Odontesthes bonariensis (Cuvier and Valenciennes 1835), from north-western Argentina was studied from monthly captures between November 1997 and March 1999. The spawning period and lengths thereof were analysed using gonadosomatic index (GSI) curves and monthly percentage distributions of maturation stages. A single

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 ...

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.

The goal of this study was to evaluate the essential components controlling the brain-pituitary-gonad axis during pejerrey (Odontesthes bonariensis) oogenesis in the wild. Ovarian developmental stages from vitellogenesis up to ovulation were associated with increasing day length and water temperatures below 21°C (winter and beginning of spring ...

Effects of Hypoxia on the Reproductive Endocrine Axis of the Pejerrey (Odontesthes Bonariensis)
Fish Physiology and BiochemistryRecently, hypoxic areas have been identified in water bodies of the Pampas region due to human activity. The objective of this work was to study the effect of low concentrations of dissolved oxygen (hypoxia) on the reproductive endocrine axis of a pampas fish (Odontesthes bonariensis). Groups of 8 males and 8 females were subjected to severe hypoxia (2-
