Species of new world silversides (Actinopterygii; Atherinopsidae; genus Odontesthes) possess economic relevance, biological interest and ecological importance. In the present paper we: (A) investigate the molecular diversity in marine species of Odontesthes from the South West Atlantic Ocean (SWAO), and analyse their interspecific relationships and ...

AbstractThe idengification of incipient ecological species represents an opportunity to investigate current evolutionary process where adaptive divergence and reproductive isolation are associated. In this study we analysed the genetic structure of marine and estuarine populations of the silverside fishOdontesthes argentinensisusing nine microsatellite

Journal of the World Aquaculture Society, 2010 The aim of this study was to evaluate the effects of temperature on survival and growth of juvenile marine pejerrey, Odontesthes argentinensis. Juveniles were randomly distributed into plastic tanks (100 L) with 50 juveniles per tank. The growth experiment was carried out at four temperatures: 20, 23, 26, and 29 C with triplicate tanks for each ...

The present study investigated the effects of water temperature (18, 21, and 25 °C) on the histological process of gonadal sex differentiation of two commercially important atherinid fishes from South America, Odontesthes argentinensis (sea pejerrey) and Patagonina hatcheri (Patagonian freshwater pejerrey).

Accidental discharges and oil spills are frequent around the world. Petroleum-derived hydrocarbons are considered one of the main pollutants of aquatic ecosystem. The importance of petroleum and refined fuels is notorious because today's society depends on them.

Abstract The present study was conducted to evaluate the effects of two commercial yeast products (Y1 and Y2) that were administered via Artemia sp. enrichment on the survival, growth, histomorphometry, immunohistochemical and stress tolerance of pejerrey larvae. The larvae received enriched Artemia for 20 days.

Gene Reports, 2018
Abstract One of the most common transitions observed in actinopterygian fishes were from marine to freshwater environments. This phenomenon could suggest that osmoregulatory mechanisms in this group are particularly adaptable to salinity changes. The silversides of genus Odontesthes are not the exception within Atherinomorpha, with several invasions ...

The knowledge about the occurrence and biochemical characteristics of key digestive enzymes is crucial for an enhanced understanding of the dietary ecophysiology of the species. On the other hand, integrative studies on digestive physiology and on tissue content of glycogen, glucose, lipid and protein in groups of ecological and economic importance are

In order to assess the metal pollution in the southwestern Atlantic coast, levels of eleven metals: Ba, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Sr, and Zn and one metalloid: As in water and tissues of Odontesthes argentinensis from the Samborombón Bay (SB) and Partido de La Costa (PC) were examined.

Odontesthes argentinensis was collected from Mar Chiquita Coastal Lagoon, the Southernmost coastal Atlantic Lagoon of Argentina. The morphology of the gills was analyzed by scanning electron microscopy. The morphology of the superficial structures of the gill filaments and pharyngeal region of the gill arch was discussed and related to their functional
