[EN] BackgroundThe impossibility of closing the life cycle of the European eel (Anguilla anguilla) in captivity troubles the future of this critically endangered species. In addition, the European eel is a highly valued ...
[EN] The critical situation of the European eel (Anguilla anguilla) has urged the development of sperm cryopreservation protocols for reproduction in captivity and cryobanking. In the last years, two research groups have ...

[ES] Resumen
Como pez de gran valor económico, procedente de una de las líneas de teleósteos más antiguas, con un ciclo de vida misterioso, un potencial de acuicultura excepcional, y con importancia cultural y actividades ...
[EN] Positive effects of probiotics on fish reproduction have been reported in several species. In the present study, 40 male European eels were weekly treated with recombinant hCG for 9 weeks and with three different ...

[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 ...
[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 ...

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 ...

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 ...

[EN] This study evaluates the effects of temperature on hCG-induced spermatogenesis in European eel (Anguilla anguilla), subjected to three thermal regimes: T10: 10 degrees C (first 4 weeks), 15 degrees C (next 3 weeks) ...
[EN] Wild female European eels were matured with CPE (carp pituitary extract) under three thermal regimes, two of
which were variable (T10–15 and T15–18, moving from 10 to 15 °C and from 15 to 18 °C, respectively) and ...
[EN] Activation at fertilization of the vertebrate egg is triggered by Ca2+ waves. Recent studies suggest the phospholipase C zeta (PLC zeta), a sperm-specific protein, triggers egg activation by an 1P3-mediated Ca2+ release ...
