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.

Female reproductive biology of the silverside Odontesthes regia

Fisheries Research, 2011
Abstract Histological observations of gonads, size frequency distribution of oocytes, seasonal changes in the gonadosomatic index and fecundity were used to assess the reproductive biology of females of the silverside Odontesthes regia from October 2006 to November 2007 in southern Chile. Six developmental stages were characterised as a function of

The role of amides in seminal cryopreservation of wild silverside, Odontesthes bonariensis

Cryobiology, 2016
Amides 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).

Effects of Hypoxia on the Reproductive Endocrine Axis of the Pejerrey (Odontesthes Bonariensis)

Fish Physiology and Biochemistry
Recently, 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-
