Towards a standardized characterization of the potentially migrating silver European eel (Anguilla anguilla L.) [PDF]

, 2005
We defined a standardized method for discriminating candidate silver eels that may undergo catadromous migration in the following season from the sedentary fraction of a population.

Eel Kisspeptins: Identification, Functional Activity, and Inhibition on both Pituitary LH and GnRH Receptor Expression

Frontiers in Endocrinology, 2018
The European eel (Anguilla anguilla) presents a blockade of sexual maturation at a prepubertal stage due to a deficient production of gonadotropins.

Developmental dynamics of cone photoreceptors in the eel [PDF]

, 2009
Background: Many fish alter their expressed visual pigments during development. The number of retinal opsins expressed and their type is normally related to the environment in which they live.

Differential timing of gene expression regulation between leptocephali of the two Anguilla eel species in the Sargasso Sea [PDF]

, 2011
The unique life-history characteristics of North Atlantic catadromous eels have long intrigued evolutionary biologists, especially with respect to mechanisms that could explain their persistence as two ecologically very similar but reproductively and ...

The yellow European eel (Anguilla anguilla L.) may adopt a sedentary lifestyle in inland freshwaters [PDF]

, 2005
We analysed the movements of the growing yellow phase using a long-term mark–recapture programme on European eels in a small catchment (the Frémur, France). The results showed that of the yellow eels (>200 mm) recaptured, more than 90% were recaptured at

Spatial distribution of an eel population (Anguilla anguilla L.) in a small coastal catchments of northern Brittany (France). Consequences hydraulic works. [PDF]

, 1998
The Frémur is a 60 km2 catchment of Brittany where many hydraulic works (dams, weirs, gauging structures, etc.) have reduced the recruitment by elvers and glass eels since at least 50 years.
