Pour une meilleure prise en compte de la faune ichtyaire à l'occasion des aménagements de rivières
Taking into account fish populations when developing rivers
Conseil Supérieur de la Pêche, Délégation Régionale pour l'Auvergne et le Limousin
Fish populations are distributed according to the characteristics of the environment and the requirements of the various species. Some indications show a certain variability of populations related to the fluctuations of parameters in the ecosystem. The examination of vital cycles shows up the specific needs and the consequences of natural or anthropical modifications of the environment. Some examples show the consequences of some developments on fish populations. Consideration of fish requirements has apparently changed favourably over the last few years. More numerous on site tracking has, however, led to less empiricism which usually prevailed on certain occasions in waterway upkeep. No section of the aquatic environment can be considered in isolation out of the context of the catchment area.
