Growth and Histopathological Effects of Chronic Exposition of Marine Pejerrey Odontesthes argentinensis Larvae to Petroleum Water-Soluble Fraction (WSF) [PDF]

AMBIO, 2012
The water-soluble fraction (WSF) of petroleum contains a mixture of polycyclic aromatic hydrocarbons, volatile hydrocarbons, phenols, and heterocyclic compounds, considered deleterious to aquatic biota. Marine "pejerrey" Odontesthes argentinensis (Teleostei: Atherinopsidae) has a great commercial importance in local fisheries and a high potential for ...

Cross-amplification of microsatellites from the Atherinopsidae Odontesthes perugiae and Odontesthes argentinensis to Chilean silversides of the genus Odontesthes and Basilichthys Amplificación cruzada de microsatélites de los Atherinopsidae Odontesthes perugiae y Odontesthes argentinensis en pejerreyes chilenos del género Odontesthes y Basilichthys

Gayana, 2011
We tested the amplification potential of 8 microsatellites initially described for Odontesthes perugiae and O. argentinensis in 3 species of Odontesthes and 4 species of Basilichthys.

Toxicidade aguda do nitrito em larvas do peixe-rei marinho Odontesthes argentinensis (Teleostei, Atherinopsidae) [PDF]

Ciencia Rural, 2006
Este trabalho visou a determinar o efeito tóxico do nitrito sobre larvas do peixe-rei marinho Odontesthes argentinensis através de testes agudos com 96h de duração. As larvas utilizadas neste experimento foram cultivadas no Laboratório de Maricultura da FURG (Rio Grande - RS). Foi utilizada água do mar filtrada na salinidade 35‰, na temperatura de 23°C,

Survival and Growth of Juvenile Marine Pejerrey, Odontesthes argentinensis, Reared at Different Temperatures

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 ...

Evidence of a landlocked reproducing population of the marine pejerrey Odontesthes argentinensis (Actinopterygii; Atherinopsidae) [PDF]

Journal of Fish Biology, 2019
AbstractIn South America, the order Atheriniformes includes the monophyletic genusOdontestheswith 20 species that inhabit freshwater, estuarine and coastal environments. PejerreyOdontesthes argentinensisis widely distributed in coastal and estuarine areas of the Atlantic Ocean and is known to foray into estuaries of river systems, particularly in ...

Parasite assemblages as indicators of an incipient speciation process of Odontesthes argentinensis in an estuarine environment

Estuarine, Coastal and Shelf Science, 2021
Abstract The silverside Odontesthes argentinensis is commonly reported as a euryhaline species, capable of using estuaries as nurseries and/or feeding grounds. However, in Mar Chiquita Coastal Lagoon system (MCH), northern Argentine Sea, substantial genetic differences have been observed between estuarine and adjacent marine populations of this ...

Presence of trace elements in the silverside Odontesthes argentinensis

Marine Pollution Bulletin, 2017
The silverside Odontesthes argentinensis is an economically significant resource for commercial fisheries in South America. We evaluated the presence of trace elements in the stomach content and fish tissues (muscle and otoliths) of O. argentinensis. In addition, we assessed the presence of trace elements in its prey (zooplankton) and in seawater in a ...
