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 ...
Triploid Induction in the Yellowtail Tetra, Astyanax altiparanae, Using Temperature Shock: Tools for Conservation and Aquaculture
(Wiley-Blackwell, 2017-10-01)
Triploidization is an interesting tool to produce sterile fish. In the yellowtail tetra, Astyanax altiparanae, this can be applied for aquaculture and surrogate technologies. In this study, we compared the efficacy of cold ...
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 ...
Sperm quality of spontaneously occurring gynogenetic males in the yellowtail tetra Astyanax altiparanae
(2021-01-01)
Gynogenesis is a chromosomal manipulation technique where an offspring is generated exclusively from maternal inheritance. In the yellowtail tetra (Astyanax altiparanae) almost all gynogenetic fish were females, suggesting ...
Pathological assessment of farmed yellowtail tetra Astyanax altiparanae infested by Acusicola sp. (Ergasilidae)
(2015-11-01)
This study registers for the first time the copepod Acusicola sp. infesting the gills of farmed yellowtail tetra Astyanax altiparanae, as well as new information on gross pathology and gill alterations. Five specimens of ...
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 ...
