“…A large data set of 1601 local fish surveys in 6 large streams over an 8-year period was analysed. Sampling surveys were adapted to large streams and considered spatial units of several square meters (between 6 and 90 m 2 ) in subunits of stream reaches (for comparable sampling strategies, see Vadas and Orth 1993;Pouilly and Souchon 1994;Thévenet and Statzner 1999). Multivariate habitat use models were built using Log densities versus different classes of hydraulic variables (see Lamouroux et al 1998 for details of methodology, particularly for the elimination of effects in multi-sites studies).…”

Abstract. -Despite IFIM worldwide success, some criticisms have not been sufficiently addressed in the literature: lack of sufficient validation of the relationships between potential available habitat and biomass of fish, particularly in warmwater streams; complexity of habitat modelling; too narrow focus on selected fish species habitat instead of entire riverine ecosystem; complexity and expense of implementation. First, we briefly address the general context of ecological flows methods. Second, we present some successful validations of microhabitat applications at the fish population (Brown trout, Salmo trutta, L. 1758) and community levels. Finally, we present the results of the statistical analysis and modelling of about one hundred Phabsim simulations. The functions of habitat (WUA) versus discharge could be predicted by synthetic hydraulic variables, in particular the Froude and Reynolds numbers. A simplified alternative to Phabsim, named Estimhab opens the way to habitat measurements in a great number of sites, particularly useful to view habitat at entire watershed level.

“…Other monospecific approaches have completed these previous preference curves: brown trout (Belaud et al, 1989;Haury et al, 1999;Roussel et al, 1999), Atlantic salmon (Heggenes et al, 1999), grayling (Thymallus thymallus, L. 1758) (Sempeski and Gaudin, 1995 a, b;Mallet et al, 2000), barbel (Barbus barbus, L. 1758) (Pouilly and Souchon, 1994), chub (Leuciscus cephalus, L. 1766) (Allouche et al, 2000), 0+ and juvenile cyprinids of large river floodplain (Pont and Nicolas, 2000; Berrebi-dit-Thomas et al, 1999).…”

Characteristics of French water bodies and fish fauna are described with special reference to physically altered streams. Recent researches on fish physical habitat have produced new insights on: models of probability of fish distributions at a watershed scale, fish ecology, in particular about their habitat preferences, hydraulic statistical modelling with simplification of data collection, models of impacts of flow or modifications to stream morphology, and coupling physics and biology. These models have been validated at fish population (trout) or assemblage (Rhône river) level.Other complementary researches are dealing with fluvial dynamics necessary to maintain habitat or with ecological dynamic linked to flows and morphology (especially substrate).For the legal point of view, Fishing law (1984 in FCE a), Water law (1992 in FCE b), and the last European Water Framework Directive (2000) defined the limits of hydrosystems utilization. They defended the principle of an equilibrium between hydrosystems utilization.It is also necessary to better link streams and their watersheds. Waterbodies regionalization will be a good way to reduce the natural variability of physical and biological situations in order to better manage ecological entities with respect of their sensitivity. The setting of a national survey of fish communities is fundamental.National conservation programmes with main protected areas of France has not been very successful at protecting freshwater fish. Rehabilitation plans of some emblematic fish species Salmon, Sturgeon, Eel, Shad have helped to coordinate actions in large heavily anthropised rivers. In other numerous aquatic systems, it is better to restore the functioning of the first key compartments, hydrology and morphology. Fish communities are in these cases good measures of the benefits of rehabilitation actions. Future research will deal with different interfaces between physics and biology, in order to better manage channels, sediments, flows, and riparian vegetation.

“…D'autre part, ces variables devraient être complétées par d'autres tout aussi importantes pour les poissons (abris, végétation) et analysées simultanément dans des modèles multivariés. De tels modèles sont en cours de développement (POUILLY et SOUCHON, 1994 ;POUILLY, 1994). Les abris ne sont que partiellement pris en compte par la granulométrie du substrat ; des travaux de recherches ont d'ores et déjà été entrepris pour mieux comprendre leur rôle dans la sélection de l'habitat par les poissons afin de pouvoir les inclure dans les modèles.…”

RÉSUMÉCette note expose, à la demande d'utilisateurs potentiels, le protocole précis de mise en oeuvre de la méthode des microhabitats développée au CEMAGREF de Lyon depuis 1985 et adaptée de l'IFIM de l'US Fish and Wildlife Service. Les principes des modèles inclus dans la méthode sont présentés. Les protocoles de mesures sont expliqués en fonction du modèle hydraulique et de la méthode de couplage des informations hydrauliques et biologiques. Les limites d'application sont ensuite exposées.Mots-clés : méthode des microhabitats, habitat des poissons, modèle hydraulique, modèle biologique, couplage physique-biologique. MICROHABITAT METHODOLOGY : PRINCIPLES AND PROCEDURES. ABSTRACTIn this note, we present, on potential users request, the microhabitat methodology procedures developed by CEMAGREF since 1985 and adapted from IFIM (US Fish and Wildlife Service). The models principles involved in this methodology are exposed. Measurement procedures are explained in the light of the hydraulic model principle and of the crossing procedure of biological and hydraulic informations. Application limits are exposed.
