Genotypic sex determination in teleosts: Insights from the testis-determining amhy gene
(Academic Press Inc Elsevier Science, 2013-10-01)
The master sex-determining genes identified so far in fishes are clearly not conserved, as evidenced by several unrelated genes reported to play critical roles in sex determination. In this study, we reviewed the molecular ...
Displacement of native Patagonian freshwater silverside populations (Odontesthes hatcheri, Atherinopsidae) by introgressive hybridization with introduced O. bonariensis
(Springer, 2017-03)
The Patagonian silverside Odontesthes hatcheri is a native fish restricted to streams and lakes of Patagonia (Argentina and Chile). Stocking programs to enhance recreational fisheries in man-made reservoirs have introduced ...
The effects of CO2 level and temperature on embryos and free embryos of the Patagonian pejerrey Odontesthes hatcheri (Actinopterygii, Atherinopsidae)
Climate Change includes an increase of both the concentration of atmospheric CO2 and of global temperature. Embryos (= eggs) of Odontesthes hatcheri were collected in spring–summer from the littoral of Lake Morenito (Andes ...
Populations of Odontesthes (Teleostei: Atheriniformes) in the Andean Region of Southern South America: body shape and hybrid individuals
(Sociedade Brasileira de Ictiologia, 2015-03-31)
The Ooriginal distribution area of the Patagonian "pejerrey" Odontesthes hatcheri has been subjected in the last few decades to the introduction of a closely related species of "pejerrey"; the Bonaerensean Odontesthes ...
Accumulation and biochemical effects of microcystin-LR on the Patagonian pejerrey (Odontesthes hatcheri) fed with the toxic cyanobacteria Microcystis aeruginosa
(Springer, 2013-03)
We studied accumulation and biochemical effects of microcystin-LR (MCLR) in Odontesthes hatcheri after dietary administration of the cyanobacteria Microcystis aeruginosa (1.3 μg MCLR / g body mass,incorporated in standard ...

Descripción y comparación de las estructuras asociadas con la alimentación en cuatro especies de peces aterinópsidos con potencial para la acuicultura
(Universidad Michoacana de San Nicolás de Hidalgo, 2012-03)
The morphology of orobranchial structures is key in the process and habits of fish feeding. Thus, according to the feeding habits, there may be marked structural differences between different species that reflect different ...
