“…Freshwater fish are one of the animal groups with higher number of invasive species (Hulme et al, 2009). The weak resistance of lacustrine habitats to fish invaders (Irz et al, 2004) results in within-lake alterations in trophic relationships and substantial effects on lake biodiversity (Vitule et al, 2009). Since their impact is widespread and relatively well documented, the changes in trophic relationships in lakes associated with invasive species offer new opportunities to study the effects of trophic changes in different biogeographic regions (Brose et al, 2004).…”

“…Fish data were collected from 30 natural lakes and 59 reservoirs among these 146 lakes (Figure 1). The lake data set represented a wide range of each environmental condition (Table 1), but as demonstrated in previous works on French lakes (Argillier et al 2002b;Irz et al 2004a;Irz et al 2002), sites with altitudes over 1500 meters above sea level had to be excluded from these analyses because they shelter only introduced fish species. Scheduled locations of Figure 1 and Table 1.…”

Launois L, Veslot J, Irz P, Argillier C. Selecting fish‐based metrics responding to human pressures in French natural lakes and reservoirs: towards the development of a fish‐based index (FBI) for French lakes. Ecology of Freshwater Fish 2011: 20: 120–132. © 2010 John Wiley & Sons A/S Abstract – Fish‐based indices of biotic integrity have been developed for many lotic systems but remain scarce for lakes. The goal of this study was to assess the responses of lentic fish assemblages to anthropogenic pressures when environmental variability was controlled for and to compare them between French natural lakes and reservoirs. Environmental features, catchment‐scale anthropogenic descriptors and fish data were collected from 30 natural lakes and 59 reservoirs throughout France. Functional fish metrics were regressed against both anthropogenic variables and the natural environmental conditions. Our results show that fish assemblages are appropriate ecological indicators for both natural and artificial lakes. They underline the necessity to control for the environment when developing indices at broad geographical scales. The relevant metrics differ between natural lakes and reservoirs, which challenges the attempts to use natural systems as references to assess the ecological potential of artificial ones.

Les populations de poissons dans le réservoir du Mirgenbach (1986-2006 : un modèle pour l'étude des effets d'un changement thermique global ?Fish populations in the Mirgenbach reservoir (1986-2006 Résumé -Depuis 1986, le réservoir du Mirgenbach, mis en eau en 1985 reçoit les eaux échauffées issues de la centrale électronucléaire de Cattenom. Les conditions physicochimiques et la biomasse chlorophyllienne sont étudiées depuis cette date, les poissons étant échantillonnés selon un protocole standardisé depuis le couplage de la dernière tranche, en 1991. L'évolution thermique est décrite puis comparée à d'autres systèmes naturels ou échauffés. Dans le Mirgenbach, l'isolement des populations de poissons et le brassage de l'eau facilitent l'observation d'une incidence des rejets sur l'évolution du peuplement, l'abondance des populations et les traits biologiques individuels. Le seuil élevé de la température hivernale et son augmentation précoce déclenchent une reproduction et un développement individuels rapides. Le plan d'eau connaît un déclin régulier de la biomasse (chlorophylle et poissons) tandis que la contamination cuprique augmente. La diminution progressive pour plusieurs espèces, des effectifs, de la longévité, des longueurs maximales, de l'âge et de la taille à maturité sexuelle contribuent au déclin de la masse globale ou individuelle maximale. L'effet de ces contraintes s'observa d'abord sur les perches et gardons avant de s'étendre aux espèces thermophiles (brèmes communes et bordelières, perche soleil). D'après l'examen de la littérature, ces observations résulteraient de l'altération du développement sexuel et du défaut croissant en ressource trophique. Mots clés -rejets thermiques, poisson, traits biologiques Abstract -The Mirgenbach reservoir was filled in 1985 and received since 1986 the overheated cooling waters of the electronuclear power plant of Cattenom. Physicochemical conditions and chlorophyll biomass were studied from that time. Fishes were sampled according to a standardized protocol since the coupling of the last unit in 1991. The thermal evolution was described then compared with the other natural or overheated systems. In the Mirgenbach, the isolation of fish populations with well mixed waters, facilitated the observation of incidence of the discharges on community evolution, abundance of populations and individual biological traits. The high threshold of the wintry temperature and its early rise set off the reproduction and causes a fast individual development. The reservoir knew a regular decline of the biomass (chlorophyll and fishes) whereas copper contamination increased. The progressive decrease for several species, of population size, longevity, maximal lengths, size and age of sexual maturity, contributed to the decline of the global or individual maximal mass. These constraints pressed at first on perch and roach and then on thermophilic species (bream and silver bream, pumpkinseed fish). According to literature, these constraints may be explained by a sexual developmental i...
