Effects of cold seawater pre-treatments on induction of early sexual maturation and sperm production in European eel (Anguilla anguilla)

Pires-Ferrão, María Leonor; Morini, Marina; González-López, Wendy Ángela; Gallego Albiach, Victor; Felip, Alicia; Pérez Igualada, Luz María; Asturiano, Juan F. (Springer-Verlag, 2024-09-05)

[EN] To induce sexual maturation in captivity, eels rely on hormonal treatments, but this process is costly and time-consuming. As an alternative, different types of conditioning, also referred as pre-treatment, have been ...
Ex vivo exposure to titanium dioxide and silver nanoparticles mildly affect sperm of gilthead seabream (Sparus aurata) - A multiparameter spermiotoxicity approach

Carvalhais, A.; Oliveira, I. B.; Oliveira, H.; Oliveira, C. C. V.; Pires-Ferrão, María Leonor; Cabrita, E.; Asturiano, Juan F.; Guilherme, S.; Pacheco, M.; Mieiro, C.L. (Elsevier, 2022-04)

[EN] Nanoparticles (NP) are potentially repmtoxic, which may compromise the success of populations. However, the reprotoxicity of NP is still scarcely addressed in marine fish. Therefore, we evaluated the impacts of ...
Exposure to silver and titanium dioxide nanoparticles at supra-environmental concentrations decreased sperm motility and affected spermatozoa subpopulations in gilthead seabream, Sparus aurata

Pires-Ferrão, María Leonor; Oliveira, Catarina C.V.; Gallego Albiach, Victor; Mieiro, Cláudia; Oliveira, Isabel B.; Carvalhais, Ana; Cabrita, Elsa; Pachedo, Mario (Springer-Verlag, 2023-07-12)

[EN] Marine pollution by nanoparticles (NPs) can be reprotoxic for fish and disturb successful reproduction of wild populations. In gilthead seabream (Sparus aurata), a mild effect on sperm motility was observed after ...
Successful cryopreservation in biodegradable containers of sperm from aquaculture Mediterranean fishes

de Souza-França, Thales; González-López, Wendy Ángela; Padilla-Sanchez, Malbelys; Pires-Ferrão, María Leonor; Fernández-García, Fátima; Borges, L.P.; Belenguer, A.; Holhorea, P.G.; Calduch-Giner, J.C.; Felip, A.; Gómez, A.; Pérez-Sánchez, J.; Streit Jr., D.P.; Asturiano, Juan F. (Elsevier, 2024-03-01)

[EN] We aimed to evaluate the efficiency of hard-gelatin and hard-hydroxypropyl methylcellulose (HPMC) capsules as biodegradable alternative containers to plastic straws in European eel (Anguilla anguilla), gilthead seabream ...
Superoxidase dismutases (SODs) in the European eel: Gene characterization, expression response to temperature combined with hormonal maturation and possible migratory implications

Pires-Ferrão, María Leonor; Blanes-García, Marta; Pérez Igualada, Luz María; Asturiano, Juan F.; Morini, Marina (Elsevier, 2024-04)

[EN] Superoxide dismutases (SODs) are antioxidant enzymes that protect cells from oxidation. Three SODs have been identified in mammals, but there is limited information in teleosts. This study investigates SODs in the ...
