Mitochondrial genome architecture and phylogenetic relationships of Odontesthes argentinensis within Atherinomorpha

Genetica, 2021
Silversides are a widely distributed group across South America, with several species occupying marine, freshwater and estuarine environments. Several authors suggest main transitions among these environments took place during Pleistocene, and were accompanied with rapid speciation events.

Oxidative stress and physiological impacts of microplastic and elevated temperatures on Odontesthes argentinensis larvae

Fish Physiology and Biochemistry
Plastics are ubiquitous in the environment, widely used in diverse industrial applications, yet they pose escalating environmental challenges due to their persistence and bioaccumulative potential as microplastics (MP). Alongside this, the average global temperature increase represents an additional physiological stressor for many species.

Seasonal and ontogenetic change in diet composition of wild new world silverside Odontesthes argentinensis in temperate coastal area (South America)

Estuarine, Coastal and Shelf Science, 2022
The Southwestern Atlantic coast (32–38°S) is one of the regions most affected by environmental changes (temperature, salinity, etc.), which can influence all life stages of fish species like de ones belong to the family Atherinopsidae (neotropical silversides).

Gonadal development in a landlocked population of pejerrey fish Odontesthes argentinensis during spawning season in relation to sex steroids and water temperature

New Zealand Journal of Marine and Freshwater Research, 2021
ABSTRACT The relationship between water temperature and gonadal maturation of a landlocked ecophenotype of marine pejerrey ( Odontesthes argentinensis ) in La Salada de Pedro Luro lake was analysed during three spawning seasons.

Artemia enriched with hydrolyzed yeast improves growth and stress resistance of marine pejerrey Odontesthes argentinensis larvae

Aquaculture, 2015
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.

De-novo assembly and transcriptome analysis of Odontesthes argentinensis gill tissue, with development of single sequence repeat markers

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 ...

Digestive and metabolic profile of the resident population of the silverside Odontesthes argentinensis from Mar Chiquita Coastal Lagoon (Buenos Aires, Argentina)

Journal of Comparative Physiology B
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

Metabolic flexibility and seasonal physiological responses of the resident silverside Odontesthes argentinensis in a southwestern Atlantic coastal lagoon

Journal of Fish Biology
Abstract Seasonal fluctuations in temperature, salinity and food availability impose strong physiological demands on fishes inhabiting temperate estuaries. Here, we examine how the resident population of Odontesthes argentinensis from the Mar Chiquita Coastal Lagoon ...
