Ecotoxicological tests with cadmium and chromium using postlarvae of silverside Odontesthes (Austromenidia) regia regia Hildebrand

Revista Peruana de Biología, 2014
In the present paper, the mean effective concentrations (EC50%) of cadmium (Cd+2) and chromium (Cr+6) using postlarvae of the silverside fish Odontesthes (Austromenidia) regia regia were determined. The postlarvae were exposed to different concentrations

Gene and Blood Analysis Reveal That Transfer from Brackish Water to Freshwater Is More Stressful to the Silverside Odontesthes humensis

Frontiers in Genetics, 2018
Silversides are fish that inhabit marine coastal waters, coastal lagoons, and estuarine regions in southern South America. The freshwater (FW) silversides have the ability to tolerate salinity variations.

Unravelling Stock Spatial Structure of Silverside Odontesthes argentinensis (Valenciennes, 1835) from the North Argentinian Coast by Otoliths Shape Analysis [PDF]

Fishes, 2022
The marine silverside (Odontesthes argentinensis) is an euryhaline species, distributed along the southwest coast of the Atlantic Ocean, present in estuaries, brackish coastal lagoons and shallow marine waters.

A Duplicated, Truncated amh Gene Is Involved in Male Sex Determination in an Old World Silverside

G3: Genes, Genomes, Genetics, 2017
A master sex-determining gene, the Y chromosome-linked anti-Müllerian hormone (amhy) gene, has been described in two New World atheriniform species but little is known on the distribution, evolution, and function(s) of this gene in other Atheriniformes ...

Evidence for Countergradient Growth Adaptation and Jordan's Rule in a Southern Hemisphere Fish, the Atherinopsid <i>Odontesthes regia</i>. [PDF]

Ecol Evol
We performed common garden experiments on offspring of the sea silverside Odontesthes regia to characterize thermal growth reaction norms of different populations along the Chilean coast. This showed that the species exhibits local adaptation in the form of countergradient growth adaptation because higher‐latitude southern populations grew faster at ...

Effects of Feeding Frequency on Liver Transcriptome: Unveiling Appetite-Regulating Peptides in Mexican Pike Silverside (Chirostoma estor)

Fishes
The Mexican pike silverside (Chirostoma estor) is a zooplanktivorous, agastric short-intestined species, and it has been found that increased-frequency feeding (twelve feedings a day) improved feed efficiency and promoted growth by 70%.

Ancient and Recent Riverine Gene Flow Contributed to the Adaptive Radiation of Sailfin Silversides in Wallace's Dreampond. [PDF]

Mol Ecol
ABSTRACT While adaptive radiations significantly contribute to the world's biodiversity, much is unknown about the genetic and ecological factors underlying these rapid successions of speciation. It has been suggested that hybridisation can facilitate the speciation process by generating genetic diversity on which diversifying selection can act ...

A data-limited approach to determine the status of the artisanal fishery of sea silverside in southern Chile

Marine and Fishery Sciences, 2022
Artisanal fisheries are essential, but for most the status of the stock supporting the fishing activity remains unknown due to lack of data and difficult access to sampling. For example, the artisanal fishery of sea silverside Odontesthes (Austromenidia)

Abundance Trends, Distribution, and Habitat Associations of the Invasive Mississippi Silverside (Menidia audens) in the Sacramento–San Joaquin Delta, California, USA

San Francisco Estuary and Watershed Science, 2016
doi: http://dx.doi.org/10.15447/sfews.2016v14iss1art2Although many alien fish species have colonized the Sacramento–San Joaquin Delta (Delta), few are as pervasive and abundant as Mississippi Silversides (Menidia audens).
