Temporal patterns in the upstream migration of European glass eels (Anguilla anguilla) at the Couesnon estuarine dam
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. The dam which is located close to the river mouth constitutes a major obstacle for upstreammigrating glass eels. The migration was observed at different temporal scales, from within individual tides to complete ti...
متن کاملComparative imaging of European eels (Anguilla anguilla) for the evaluation of swimbladder nematode (Anguillicoloides crassus) infestation.
This study compares diagnostic imaging tools in detecting the parasitic swimbladder nematode Anguillicoloides crassus in Anguilla anguilla (L.) and focuses on ultrasound in an attempt to develop a non-destructive, field diagnostic test. Ultrasound use could allow the parasite to be diagnosed without decreasing the number of critically endangered European eels through post-mortem. In the prelimi...

The changes in bacteriolytic and proteolytic activities of skin cathepsins L and B were studied Ž . in thermal-stressed European eel Anguilla anguilla . When fish were kept in 108C water, all activities increased to reach maximum levels at Day 8 with varying increasing rates of 3.0 Ž . Ž . Ž . proteolysis , 4.2 lysis of FlaÕobacterium columnare , 5.7 lysis of Vibrio anguillarum and 7.8 Ž . lysi...
متن کاملUltrasonographic predictors of response of European eels (Anguilla anguilla) to hormonal treatment for induction of ovarian development.
OBJECTIVE To examine ultrasonographic predictors of ovarian development in European eels (Anguilla anguilla) undergoing hormonal treatment for assisted reproduction. ANIMALS 83 female European eels. PROCEDURES Eels received weekly IM injections of salmon pituitary extract (first injection = week 1). Ultrasonography of the ovaries was performed twice during hormonal treatment (weeks 7 and 11). E...
متن کاملDifferential gene expression analysis in European eels (Anguilla anguilla, L. 1758) naturally infected by macroparasites.
We analyzed the relationships between the macroparasite community of the European eel and the expression of genes involved in the host physiology during its continental life. The genes studied are implicated in (1) host response to environmental stress, i.e., heat shock protein 70 (HSP70) and metallothionein (MT); (2) osmoregulation, i.e., beta thyroid hormone receptor (betaTHR) and Na+/K+ATPas...
