Study to draw up suitability curves of endemic fishes of freshwater on each regions in Taiwan

Quantifying ecological and hydrological parameters is essential for solving problems in hydrological engineering and design projects. Data on fish species, including the freshwater and estuarine fishes of Taiwan, the fish database of Taiwan from the Center for Biodiversity, Academia Sinica, and from abroad, were used to carry out an analysis on four different habitat suitability curve regimes (flow velocity, water depth, bed material and water quality) of upstream, midstream and downstream sections of rivers in five different geographical zones in Taiwan. In total, 60 habitat suitability curves were completed for the five zones. These suitability curves can be used for the evaluation of weighted usable area (WUA) and ecological design by hydrological engineers.
