Low concentrations of glyphosate-based herbicide cause complete loss of sperm motility of yellowtail tetra fish Astyanax lacustris
(2018-04-01)
Environmental relevant concentrations of glyphosate-based herbicide as 50 µg l−1, 300 µg l−1 and 1800 µg l−1 can affect sperm quality of yellowtail tetra fish Astyanax lacustris. Viability of sperm cells was impaired at ...
EFFICIENCY OF BRAZILIAN NATIVE ORNAMENTAL FISHES AS MOSQUITO LARVAE PREDATORS
(Inst Pesca, 2017-01-01)
Fish are an alternative in mosquito biological control. Some species are proven to be effective in many countries, but are Brazilian native. Brazilian species may be larvivorous but this lacks information. Therefore, the ...
ECOTOXICITY OF VINASSE FOR FISH TETRA-SERPAE (Hyphessobrycon eques) AND MACROPHYTE DUCKWEED (Lemna minor)
(Inst Pesca, 2015-01-01)
The aims of this study were to evaluate the possibility of using the tetra-serpae fish (Hyphessobrycon eques) and macrophyte duckweed (Lemna minor) as biomarkers of toxicity of vinasse, estimating the LC50 and mortality ...

Functional morphology of the tetra fish Astyanax lacustris differs between divergent habitats in the Pantanal wetlands
(Wiley-Blackwell, 2016-08-01)
This study investigated whether the body morphology of the tetra fish Astyanax lacustris ( previously Astyanax asuncionensis) varied between populations inhabiting one lagoon ( a lentic, shallow environment, with great ...
Triploid or hybrid tetra: Which is the ideal sterile host for surrogate technology?
(2018-03-01)
This work was aimed at developing an effective procedure to obtain sterile ideal host fish in mass scale with no endogenous germ cells in the germinal epithelium, owning permanent stem-cell niches able to be colonized by ...
Improvement of gamete quality and its short-term storage: an approach for biotechnology in laboratory fish
(Cambridge Univ Press, 2015-03-01)
In fish, in vitro fertilization is an important reproductive tool used as first step for application of others biotechniques as chromosome and embryo manipulation. In this study, we aimed to optimize gamete quality and ...
Effects of triploid induction on innate immunity and hematology in Astyanax altiparanae
(2021-09-01)
Triploid induction is a promising biotechnique that could be used to enhance aquaculture yields in the near future. However, studies conducted with several fish species have demonstrated that the presence of an extra set ...
A Flow Cytometry Protocol to Estimate DNA Content in the Yellowtail Tetra Astyanax altiparanae
(Frontiers Media Sa, 2017-09-25)
The production of triploid yellowtail tetra Astyanax altiparanae is a key factor to obtain permanently sterile individuals by chromosome set manipulation. Flow cytometric analysis is the main tool for confirmation of the ...
Dermocystidiosis induced by the parasite Dermocystidium sp. in the Paracheirodon axelrodi
(European Association of Fish Pathologists, 2018-04)
The Rio Negro floodplain (tributary of the Amazon River) is a natural habitat of the cardinal tetra Paracheirodon axelrodi. In home aquaria, this species has high vulnerability to superficial infetions and is affected by ...
