Suay Costa, María Isabel (Universitat Politècnica de València, 2021-10-19)[ES] Estudios recientes han descubierto que el agua marina fría estimula al eje cerebro-hipófisis-gónada e induce un desarrollo sexual temprano en los machos de anguila europea (Anguilla anguilla). Estos resultados sugieren ... -

In the present study, 40 male European eels were weekly treated with recombinant hCG for 9 weeks and with three different ... -
Herranz-Jusdado, Juan Germán; Gallego Albiach, Victor; Rozenfeld, Christoffer; MORINI, MARINA; Pérez Igualada, Luz María; Asturiano Nemesio, Juan Francisco (Elsevier, 2019)[EN] Maturation in captivity of European eel (Anguilla anguilla) requires long and costly hormonal treatments that often lead to asynchronic maturation between sexes. Therefore, optimization of sperm short-term storage ... -
Asturiano Nemesio, Juan Francisco; Sorensen, S.R.; Pérez Igualada, Luz María; Lauesen, P.; Tomkiewicz, J. (Blackwell Publishing, 2016)[EN] Contents Sperm cryopreservation is a useful tool in captive fish reproduction management, that is to synchronize gamete production, especially in the case of species as the European eel, where the time of female ...

MORINI, MARINA; Lafont, A. G.; Maugars, G.; Baloche, S.; Dufour, S.; Asturiano, Juan F.; Pérez Igualada, Luz María (Cambridge University Press, 2020-06)[EN] In teleosts, vitellogenin (Vtg) is a phospholipoglycoprotein synthesized by the liver, released into the blood circulation and incorporated into the oocytes via endocytosis mediated by the Vtg receptor (VTGR) to form ... -
Pérez Igualada, Luz María; Peñaranda, D.S.; Dufour, S.; Baloche, S.; Palstra, A. P.; Van den Thillart, G.E.E.J.M.; Asturiano Nemesio, Juan Francisco (Elsevier, 2011-10-01)[EN] We examined the effect of temperature in European silver eels during their maturation induced by injections of carp pituitary extract on endocrine parameters: pituitary fshß and lhß expression, plasma 17ß-estradiol ... -
Vílchez Olivencia, María del Carmen (Universitat Politècnica de València, 2017-11-03)In general, fish spermatozoa are immotile in the testis. Movement is activated due to the osmotic shock (hypo- or hyperosmotic, depending on fish origin: freshwater or sea water species) experienced when they are released ... -
Pérez Igualada, Luz María; Gallego Albiach, Victor; Asturiano, Juan F. (Elsevier, 2020-03-15)[EN] Sperm activation involves ion fluxes as well as a previous maturation in the seminal plasma, something which has not been studied in depth in marine fish species. pH and potassium are probably involved in sperm ... -
Rojo-Bartolomé, Iratxe; Martínez-Miguel, Leticia; Lafont, Anne-Gaëlle; Vilchez Olivencia, Maria Carmen; Asturiano Nemesio, Juan Francisco; Pérez Igualada, Luz María; Cancio, Ibon (Elsevier, 2017)[EN] Reproduction in captivity is a key study issue in Anguilla anguilla as a possible solution for its dwindling population. Understanding the mechanisms controlling the production of ribosomal building blocks during ... -
Optimización de los protocolos de conservación de gametos de anguila europea a corto y largo plazo Ortiz Casanova, María Teresa (Universitat Politècnica de València, 2021-07-23)[ES] La anguila europea (Anguilla anguilla) es una especie de elevado interés pesquero y una de las especies importantes para la acuicultura mundial, pero su producción actual todavía depende de las capturas de angulas del ... -
Pérez Igualada, Luz María; Vilchez Olivencia, Maria Carmen; Gallego Albiach, Victor; MORINI, MARINA; Peñaranda, D.S.; Asturiano Nemesio, Juan Francisco (Elsevier, 2016-01)[EN] Sperm from European eel males treated with hCG(rec), was washed in a calcium free extender, and sperm motility was activated both in the presence (seawater, SW) and in the absence of calcium (NaCI + EDTA), and treated ... -
Vilchez Olivencia, Maria Carmen; MORINI, MARINA; Peñaranda, D.S.; Gallego Albiach, Victor; Asturiano Nemesio, Juan Francisco; Pérez Igualada, Luz María (Elsevier, 2017)[EN] The role of potassium from the seminal plasma and/or the activation media was examined by selectively removing from this media, and by testing the use of channel inhibitors and a K-ionophore. Sperm motility was measured ... -
Vilchez Olivencia, Maria Carmen; MORINI, MARINA; Peñaranda, D.S.; Gallego Albiach, Victor; Asturiano Nemesio, Juan Francisco; Pérez Igualada, Luz María (Elsevier, 2016-08)[EN] The role of seminal plasma sodium and activation media sodium on sperm motility was examined by selectively removing the element from these two media, in European eel sperm. Sperm size (sperm head area) was also ... -
Gallego Albiach, Victor (Universitat Politècnica de València, 2013-12-20)The conservation status of the species studied in this thesis (European eel and pufferfish) is currently frail, thus the main goal of this research was to develop, improve and apply several techniques and protocols ... -
