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 ...

Otolith and vertebral morphology of marine atherinid species (Atheriniformes, Atherinopsidae) coexisting in the southwestern Atlantic Ocean

Ciencias Marinas, 2010
Studies on marine ecosystems rely on the identification of fish prey species of piscivores (fish, aquatic mammals, and aquatic birds) based on their bones and otoliths. The stomach contents of piscivores show predation on marine atherinids of commercial

Effects of photoperiod on survival and growth of the marine pejerreyOdontesthes argentinensislarvae

Aquaculture Research, 2009
The marine pejerrey Odontesthes argentinensis (Valenciennes) is an important commercial species in southern South America, and its culture is considered to be promising (Sampaio 2006). It is distributed in coastal and estuarine waters from the south of Brazil toArgentina (Dyer 2006).

Recruitment of juvenile fishes into a small temperate choked lagoon (Argentina) and the influence of environmental factors during the process

Scientia Marina, 2015
Juvenile fishes were sampled every 15 days from September 2009 to April 2010 along the marine-estuarine gradient (surf zone, estuary and a freshwater stream) of the Mar Chiquita lagoon, Argentina. The temporal variations of juvenile assemblages in spring-

Evidence of habitat fragmentation affecting fish movement between the Patos and Mirim coastal lagoons in southern Brazil

Neotropical Ichthyology
The communication between the Patos and Mirim lagoon systems occurs via a natural channel called São Gonçalo. In 1977, a dam was built in this channel to prevent entrance of saline waters from Patos Lagoon estuary into the Mirim Lagoon.

Diet Composition and Feeding Strategy of the New World Silverside Odontesthes argentinensis in a Temperate Coastal Area (South America)

Marine and Coastal Fisheries, 2018
Abstract The diet composition and feeding strategy of the New World silverside Odontesthes argentinensis were evaluated in a temperate coastal area during austral summer. This species is an economically significant resource for the fishing industry in South America. The food preference of O.

Within-population morphological differences in the New World silverside Odontesthes argentinensis inhabiting two coastal lagoons of Uruguay (southwestern Atlantic)

Animal Biology, 2020
Abstract Silversides are renowned for their phenotypic plasticity with different populations coexisting as incipient species. The New World silverside Odontesthes argentinensis is an estuarine-resident fish with known populations inhabiting the Rio de la Plata estuary as well as coastal lagoons of Brazil, Uruguay and Argentina, where it constitutes an ...
