| description | AbstractIt’s essential to identify the priority conservation species in the habitat restoration and biodiversity conservation. Generally, people select the valuable fishes or the commercial fishes as target species in basins, according to experts’ experience rather than the scientific evaluation. With the influence of urban development, construction of water conservancy facilities and human activities, the river habitat of the Shaying River (Xuchang section) is poor. Fish conservation studies play an important part in the habitat restoration of this river section. Thus, we studied the evaluation method for the priority protection of fishes based on multiple ecological dimensions. The method including six multidimensional indicators, namely, habitat suitability, ecological stability, species endangerment criteria, intensity of human interference, genetic value, and species value. Then, we determined the indicator weights by the analytic hierarchy process (AHP), and assessed the protection priority of fishes based on various assessment criteria and comprehensive qualitative or quantitative analyses. The result shows that Ctenopharyngodon idellus, Opsariichthys bidens, and Culter alburnus Basilewsky have priority for protection, coinciding with the status in the basin. Overall, this study complements the existing indicator species selection methods, and is more scientific and comprehensive, providing an effective method for priority protection species and river habitat restoration projects. |
