Résumé
Habitat is the place where a species lives and its surrounding biotic and abiotic environment. Ecologists seeking to develop explanatory and forecast models have long wondered about this fundamental question: how can the presence of an individual at a given place and time be explained? Indeed, the different fish species are not distributed at random in aquatic systems, but according to their biological and ecological requirements. The knowledge of factors governing the distribution of species could also improve our understanding of the structure of populations.
