Individual-based model of juvenile eel movement parametrized with computational fluid dynamics-derived flow fields informs improved fish pass design [PDF]

open access: yesRoyal Society Open Science, 2020
European eel populations have declined markedly in recent decades, caused in part by in-stream barriers, such as weirs and pumping stations, which disrupt the upstream migration of juvenile eels, or elvers, into rivers.

Developmental dynamics of cone photoreceptors in the eel [PDF]

open access: yes, 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.

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

open access: yesFrontiers 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.

First occurrence of the eel parasite Paraquimperia tenerrima in lake Balaton, Hungary [PDF]

open access: yes, 2006
The parasite fauna of the eel has been studied regularly since the first imported eels were introduced to Lake Balaton in 1963. Over a long period of time no important parasitic infections were recorded. However, the importance of nematode infections has

Pseudodactylogyrosis in Anguilla anguilla (Actinopterygii: Anguilliformes: Anguillidae): change of control strategies due to occurrence of anthelmintic resistance [PDF]

open access: yesActa Ichthyologica et Piscatoria, 2011
Background. The European eel, Anguilla anguilla (L.), is considered an endangered species and a series of protective measures have been implemented within the European community in order to enhance natural stocks.

Temporal patterns in the upstream migration of European eels (Anguilla anguilla) at the Couesnon estuarine dam [PDF]

open access: yes, 2007
The temporal migration patterns of European glass eel Anguilla anguilla at the Couesnon estuarine dam (Mont-Saint-Michel Bay, France)were examined in winter and spring 2004 and 2005.

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

open access: yes, 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.

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

open access: yes, 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 ...

American eel resilience to simulated fluid shear associated with passage through hydroelectric turbines

open access: yesKnowledge and Management of Aquatic Ecosystems, 2021
American eel (Anguilla rostrata) populations have declined within their native range along the eastern coast of North America due to factors such as commercial fishing, habitat alteration, and dams.
