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 ...

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 ...

Criação de juvenis de peixe-rei (Odontesthes argentinensis) em diferentes taxas de arraçoamento [PDF]
Ciencia Rural, 2006 Este estudo teve como objetivos avaliar os efeitos de diferentes taxas de arraçoamento sobre a sobrevivência e o crescimento de juvenis do peixe-rei (Odontesthes argentinensis). Juvenis de peixe-rei (100mg) foram estocados na densidade 10 peixes L-1, em tanques circulares de 50L. Foram testadas cinco taxas de alimentação (4, 8 12, 16 e 20% do peso vivo

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).

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,

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

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.
