Obstacles in rivers are considered to be one of the main threats to diadromous fish. As a result of the recent collapse of the European eel, the European Commission introduced a Regulation, requiring to reduce all sources of anthropogenic mortality, including those caused by passing through hydropower turbines. Improving knowledge about migration t...

Methods to study the migratory behaviourr of fish can be divided in two categories: capture-dependent (based on sampling marked or unmarked fish) and capture-independent methods, such as visual or video observation, resistivity fish counters or hydroacoustics. In this chapter we focus only on capture-dependent methods using marked fish.

Une énergie facilement disponible et bon marché a permis l'amélioration de notre qualité de vie au cours des deux derniers siècles. Cette disponibilité constitue un pilier fondateur de notre société technologique actuelle. Avec la croissance démographique mondiale qui portera à 9 milliards le nombre d'habitants sur la planète en 2050, comment faire...

En France comme en Europe, l'anguille européenne est une espèce menacée. Afin de réduire les pressions exercées sur l'espèce, il est essentiel d'intervenir sur les obstalces à sa libre circulation.

This study describes the behaviour of radio-tagged returning Atlantic salmon, Salmo salar L., at the Golfech-Malause hydroelectric complex on the River Garonne, France. The particularity of this complex is that it is fitted with a fish lift, a type of fishway rarely tested for salmon. Only forty seven percent of salmon succeeded in passing. Frequen...
Article
This study reveals the difficulties encountered by adult Atlantic salmon to pass over a large-scale hydroelectric complex, even fitted with a fish lift. A single fish pass entrance at the power station seems to be insufficient at a so large tailrace (100 m wide). Low passages are also due to such a trapping system specific to fish lifts. Factors li...

Les perturbations physiologiques potentiellement liées à la capture des poissons par filet maillant ou par épuisette ont été estimées chez des brochets, sandres, perches, brèmes, chevesnes, carpes et tanches de la retenue hydroélectrique de Pareloup (Aveyron). Toute capture provoque rapidement une hausse significative des taux de catécholamines (>1...

The potential physiological disturbances experienced by fish as a result of capture with gill nets or landing nets were assessed in pike, pikeperch, perch, bream, chub, carp and tench from the hydroelectric reservoir of Pareloup (Aveyron). Capture of fish quickly resulted in both a significant elevation of plasma catecholamine (> 10 ng.mM), cortiso...

Variations in plasma thyroxine (T4) and triiodothyronine (T3) contents of pike, pikeperch, perch, bream and chub from a large reservoir (Pareloup, South of France) were investigated before and during the progressive emptying of the reservoir. Fish were caught by gill nets, except at the last time of emptying when controls were collected with landin...

L'etat physiologique des poissons a ete estime, pour une part, par l'evaluation mensuelle, au cours de quatre annees (1984, 1989, 1990, 1991), de caracteristiques morphophysiologiques et de la composition somatique chez deux especes differant par leur regime alimentaire : la perche et le gardon. Les valeurs obtenues ont demontre qu'il y a certaines...

Lors de la vidange de la retenue de Pareloup, on pouvait supposer que la restriction de l'espace vital entrainerait des modifications de la biologie et de la physiologie des poissons.

High death rates were noted in wild perch and roach populations shortly after the stage of acclimatization in a tank. A decrease in water hardness by about 40 mg/l of CaCO3 seemed to cause the mortalities. The effect of reduced ambient Ca2+ and Mg2+ levels may be promoted by a thermal modification. Furthermore, in these conditions, couldn't we obse...

Le projet CONSACRE a l’ambition d’analyser d’un point de vue global et local, la continuité écologique piscicole de l’axe Seine. L’objectif est de proposer des pistes d’actions, qui concernent d’une part les possibilités d’aménagements pour la préservation et la restauration des milieux naturels, et d’autre part l’amélioration de l’association des différents publics impliqués dans cette problématique. https://consacre.inrae.fr/

Obstacles in rivers are considered to be one of the main threats to diadromous fish. Improving knowledge about migration triggers and processes is crucial to assess and mitigate the impact of obstacles. In our project, we explore the interplay between individual internal state, environmental conditions, and resulting individual movements of tagged silver eels in the fragmented River Dronne (Western France). More generally, it confirms that the movement ecology framework is an appropriate approach to explore this interplay in many fish radiotracking experiments in rivers.

LIFE MIGRATOEBRE project is a best practices and a demonstration project for final stretches of major European Rivers, focused on long-term sustainable investments in Natura 2000 sites and on species and habitats targeted by Habitats Directive conservation, at local and regional levels. The project is based on the implementation of mitigation measures in relation to rivers hydromorphology improvement, especially on rivers ecological connectivity and fish passage issues associated by the Water Framework Directive and the European Eel Recovery Plan (Regulation 1100/2007). The main objectives of the LIFE MIGRATOEBRE project are the conservation of the endangered anadromous fish species (European sturgeon, European eel, twait shad and sea lamprey) and the restoration of the Ebre River ecological connectivity through the interconnection of natural areas included in the Natura 2000 network. The specific objectives of the project are: 1. Recover healthy and sustainable populations of migratory fish species -European sturgeon (Acipenser sturio), European eel (Anguilla anguilla), twaite shad (Alosa fallax) and sea lamprey (Petromizon marinus)- within 20-30 years in the lower Ebre river and delta. 2. Significantly improve the ecological connectivity of the lower Ebre river, adapting all the present obstacles of the final stretch (Xerta’s weir, Ascó’s weir and Flix dam) to allow fish migration (upstream and downstream); increasing more than tenfold the river spawning habitat availability for European sturgeon, twaite shad and sea lamprey, and the distribution (and growth) area for European eel. 3. Involve community and a net of nature managers, farmers, fishermen, anglers, water managers, electric companies, tourism stakeholders, regional and local authorities working together on migratory fish recovery and improved ecological management in the final stretch of the Ebre river, on long-term sustainable investments in Natura 2000 sites on conservation of species and habitats targeted by Habitats Directive. 4. Be an exemplary project at local scale, and progressivelly to integrally promote the improvement of the ecological connectivity at the Ebre river basin. I. e. In a second stept, at Riba-roja dam -to connect the lower Ebre with an important tributary, the Segre River- and Mequinença dam -to connect the lower Ebre with the middle Ebre basin-. And also to become a demonstration project by other principal Iberian –Guadalquivir, Guadiana, Miño- and some European Rivers as well. More information at: www.migratoebre.eu
