| dc.description.abstract | Habitat degradation associated with river regulation, consequence increasing human demands on water resources, and result is changed richness and diversity fish species. Projects ecological habitat to improve becomes a priority for authorities in many countries. In the present study, a methodology based on the relationship between fish habitat and stream flows, is applied in order to determine impact the regulate flows to species. A new approach based on fuzzy sets and rules, linguistic rules describe the imprecise information which often characterizing ecological data and enable implementing the interactions between physical variables. The habitat selection of several species can be predicted adequately based on expert knowledge. Analyzed the Odelouca River, in the south-west of Portugal, when applied the CasimirFish2D model habitat to a stream downstream Odelouca Dam and the fish habitat was determined for two endemic cyprinids species, Iberian chub (Squalius aradensis) and Iberian nase (Iberochondrostoma almacai). The results validated that decrease in availability habitat exists, and changes according to ontogeny. Casimir is a good alternative to others habitat models and may be having a good applicability in fluvial restoration studies. | por |
