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).

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

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

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.

Biologia reprodutiva do peixe-rei Odontesthes argentinensis (Valenciennes) (Atherinopsidae) da região marinha costeira do sul do Brasil [PDF]
Revista Brasileira De Zoologia, 2006 O peixe-rei Odontesthes argentinensis (Valenciennes, 1835) distribui-se na região costeira do Atlântico Sul desde o sul do Brasil até a Argentina. Esta espécie apresenta duas populações, uma população residente no estuário da Lagoa dos Patos e outra na região marinha costeira.

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.

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).

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 ...
