Abstract:

Glass eels of the European eel migrate from coastal waters inland to freshwater as part of the catadromous lifecycle. The osmotic challenge faced at this time is augmented by their large surface area to volume ratio, and by the fact that the migration may only be completed after several attempts, due to the effects of tide and river flow. Glass eels and elvers developed normally when maintained in waters of differing salinity over a six month period. Drinking rates increased with environmental acclimation salinity (from 0.072 +/- 0.023 mul/g/h to 0.698 +/- 0.099 mul/g/h in FW and SW respective

L’objectif de cette thèse est d’étudier le rôle de neuropeptides cérébraux, telle que la Neurokinin B codée par le gène tac3, dans le contrôle de la reproduction d’une espèce en danger, l’anguille Européenne, Anguilla anguilla. La maturation sexuelle de l’anguille est bloquée à un stade prépubertaire avant la migration océanique. Etant donnée sa position phylogénétique basale parmi les téléostéens, l’anguille est un modèle pertinent pour étudier l’évolution moléculaire et fonctionnelle de neuropeptides d’intérêt. Deux gènes paralogues tachykinine 3 (tac3) ont été identifiés dans le génome de l

Anguilla australis glass eels proved to be resilient and present strong aquaculture potential. General husbandry techniques, anaesthesia and prophylactic treatments were established for glass eels between 0.1 g and 2.0 g and elvers between 2.0 g and 8.0 g, caught in rivers and estuaries along the South East Coast of Victoria. The protozoan parasites Ichthyobodo and Trichodina were found to be present on arrival to the hatchery developed during different rearing treatments, and were successfully eradicated.

L'anguille européenne (Anguilla anguilla) présente un cycle de vie complexe avec un stade civelle qui remonte les estuaires pour atteindre les rivières et entamer une phase de croissance. Cependant, cette migration estuarienne est connue pour être facultative, certains individus s'installant en mer, en estuaire ou alternant les séjours en rivière et en estuaire. Les civelles ne se nourrissent pas ou peu pendant leur migration et leurs schémas migratoires pourraient donc être étroitement associés aux réserves énergétiques des individus. La migration facultative des civelles pourrait donc repose

The European eel has a complex life cycle, with sexual maturation blocked in the absence of the reproductive oceanic migration, and an inability to mature in captivity without the administration of hormonal treatments. Even though experimental maturation induces gamete production of both sexes, the fertilization results in infertile eggs,

Abstract:

The European eel, Anguilla anguilla, is designated a threatened species and parasites are considered to be one of the contributory factors associated with the species decline. To address the lack of knowledge concerning parasite infections in the UK European eel population, a total of 140 specimens were obtained from the Environment Agency at 14 river sites across England and Wales. Each specimen was dissected and infection status determined for the different classes of helminth using a combination of morphological and molecular approaches, including a PCR-based restriction digestion approach

In the last 40 years, the population of European eel (Anguilla anguilla L.) has declined dramatically and is now considered to be outside safe biological limits.

The major factors regulating eel populations are still unknown and until there is an understanding of the factors causing the low recruitment of eels, the success of any management plans and conservation measures may be limited.

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 into the external medium. However, there is no consensus regarding the mechanisms that occur after activation. The aim of this project was to study the importance of the environmental ions and proteins on the activation of European eel sperm, and to apply this knowledge to the improvement of sperm quality preservation.

Abstract:

In response to the drastic decline of the European eel (Anguilla anguilla (L.)) fisheries have been reduced and elvers are stocked in areas where natural abundances are low. Are these measures adequate? To answer different aspects of this question, we have analysed more than a century of eel tagging, using both traditional and more novel capture – recapture analyses. Based on these long-term data, we have evaluated the impact of the Swedish eel coastal fisheries using Survival analysis. Our analysis indicates that the fishing mortality just prior the 2009 fishing restrictions were in the order

Abstract:

L’anguille européenne Anguilla anguilla est une espèce catadrome avec un cycle de vie complexe incluant des migrations entre la mer de Sargasses et l’Europe et l’Afrique du Nord. On a noté une baisse drastique de sa population depuis les 30 ans et on la considère aujourd’hui comme ‘en danger critique’. Une des causes principales de ce déclin est la fragmentation de l’habitat.Nous avons étudié si les obstacles aquatiques peuvent exercer un pression de sélection sur les jeunes anguilles en migration. On a utilisé une approche sans a priori, où une large liste des gènes a été analysée dans trois
