“…The large scale regulation of streams (embankments, dams and associated weirs) generally reduces overall water velocities (Belliard et al, 1995;Persat et al, 1995) as well as shallow areas used by larval and juvenile stages, especially in the foothill rivers (barbel and grayling zones) (Persat et al, 1995). In this context, grayling appears as an important target species for habitat diversity conservation.…”

The three grayling Thymallus thymallus age-classes had strong preferences for their local habitat in the Ain river. All age-classes preferred high water velocities between 70 and 110 cm s 1 , confirming that grayling is a typical rheophilic species. An important intraspecific segregation regarding depth occurred, as large individuals preferred deeper water than small ones (optimal ranges=50-60, 80-120 and 100-140 cm for 0 + , 1 + and adults respectively). The three age-classes had similar preferences for small substratum particles, with optimal values between 0·5 and 16·0 mm. Preference curves were generally comparable between the two sites, despite important differences in habitat availability. It is emphasized that grayling needs various habitat conditions to achieve its entire life cycle. The increasing scarcity of this species underlines the urgency of protecting lotic habitat integrity and diversity. 2000 The Fisheries Society of the British Isles

“…BELLIARD et al (1995) sur la Seine mettent en évidence au cours du siècle dernier, des évolutions de peuplements inverses selon les types d'aménagement. En l'absence de connaissance précise sur le type de dégradation subi par les stations étudiées, on ne peut donc pas écarter l'existence de tels mécanismes pour expliquer l'absence de sensibilité de certains paramètres.…”

“…Originellement pauvre suite aux dernières glaciations (BANARESCU, 1989), le peuplement du bassin de la Seine ne compte historiquement que 45 espèces (BELLIARD et al, 1995). Parmi ces 45 espèces près de la moitié sont des cyprinidés et 7, principalement migratrices, ont complètement disparu depuis le siècle dernier du fait de la forte pression anthropique (BELLIARD et al, 1995).…”

FISH ASSEMBLAGE ATTRIBUTES SENSITIVE TO STREAM ALTERATIONS IN THE SEINE RIVER BASIN (FRANCE). ABSTRACTTo underscore the fish assemblage attributes sensitive to river alterations, we compare 23 parameters of fish assemblages between 74 slightly disturbed sites and 133 strongly disturbed sites. These parameters characterize fish assemblages according to the species richness, the trophic regime, the feeding habitats, the habitat requirements during the life cycle, the spawning substrata and the tolerance capacities of species. Only eight parameters appear to be sensitive to perturbations : the abundance of no tolerant invertivorous individuals, the number of (no tolerant) species feeding on stony substrate, the number of no tolerant species feeding in water column, the rheophilic species richness, the abundance of (no tolerant) lithophilous individuals and the intolerant species richness. These results show that fish assemblages of the Seine River basin are sensitive to river alterations. They also exhibit the difficulty to choose parameters for developing an index based on stream fish communities, Reçu le 10 octobre

“…First we identified long migratory (i.e., amphidromous) and nonnative species. The non-native species list was built on the basis of previous on Seine basin fish fauna (Belliard et al 1995;Boët et al 1999) completed with more recent information specifying the allochthonous status of bitterling (Van Damme et al 2007). Next, we used five ecological traits: habitat preference, oxygen requirement, spawning temperature, spawning substrate and diet, each partitioned into three possible modalities (see Table 2).…”

We used historical sources from the end of the nineteenth to the mid-twentieth century and current data to retrace fish assemblage trajectories for the past 150 years on 29 river stretches distributed throughout the Seine River basin. We based our analyses on species presence/absence, occurrence of amphidromous and non-native species, and species ecological traits related to habitat preference, oxygen and temperature requirements, and diet. In accordance with general trends observed for Western Europe, we detected a general decline of amphidromous species and an increase in non-native species, even if, at some sites, several non-native species were extirpated. These changes affecting amphidromous and non-native species led to a weak increase in beta-diversity in fish assemblages. Independently of amphidromous and non-native species, for a reduced set of sites, we noted that changes in the balance of ecological traits over time, trace, in a consistent way, the major steps that affected watercourses like waterway development, increasing pollution, dam construction, or, locally, the recent wastewater treatment improvement. Despite local variations, we found contrasted trends between, on one hand, large rivers and/or catchments which had experienced strong expansion in human population, where fish assemblages had deteriorated, and, on the other hand, upstream catchments, with a declining human population, where fish assemblages showed signs of improvement. Because our results suggested that long-term changes affecting fish assemblages cannot be summarized as an unequivocal gradual degradation, we questioned the use of historical data to define ecological reference conditions for river assessment and management purposes.
