Species diversity indices provide quantitative data for understanding the variations and trends in fish species diversity, as well as information on species richness and evenness. However, these diversity indices do not reflect differences in specific taxa, which can be of importance as key conservation targets, especially during the planning and construction of protected areas. In this study, simultaneously combining our improved traditional fish fauna analysis (TFFA) with the value of fish fauna presence (VFFP) methods, we studied fish diversity in the Salween and Irrawaddy basins. The results of the TFFA reflected the families (subfamilies) and genera that constitute the main body of fish diversity in the river basins. The results of the VFFP assessment showed which families (subfamilies) and genera were representative of certain characteristics in the basins. The VFFP scores of genera could be used as indicator indices and as priority taxa in the planning and construction of fish resource reserves. In this paper, we propose for the first time that the role and status of monotypic genera (genera comprising only a single species) in the conservation of fish diversity should not be ignored, and they should rather be a priority for protection.
物种多样性指数为了解鱼类物种多样性的变化和趋势提供了定量数据，以及物种丰富度和均匀度的信息。然而，这些多样性指数并不能反映特定分类群的差异，而这些差异可能是重要的保护目标，特别是在保护区的规划和建设过程中。在这项研究中，我们同时结合改进的传统鱼类区系分析（TFFA）和鱼类区系存在值（VFFP）方法，研究了萨尔温江和伊洛瓦底江流域的鱼类多样性。TFFA 的结果反映了构成流域鱼类多样性主体的科（亚科）和属。VFFP 评估的结果表明了哪些科（亚科）和属是流域某些特征的代表。属的 VFFP 得分可用作规划和建设鱼类资源保护区的指示指数和优先分类群。在本文中，我们首次提出，单型属（仅包含一个物种的属）在保护鱼类多样性方面的作用和地位不应被忽视，而应优先保护。
