Studies on fish fauna should not only focus on fish composition and the comparison of fish composition among the study region and adjacent regions, but should also explore the origin and uniqueness of different taxa as well as the substitution of genera and species. In this study, the value of floristic presence method was modified and renamed the value of fish fauna presence (VFFP) method. The specific steps of the VFFP method and the traditional fish fauna analysis (TFFA) method were refined and standardized. Then, the VFFP and TFFA methods were applied to study the fish fauna of the upper and middle portions of the Mekong River basin. The results indicate that the TFFA method reflects the families (subfamilies) and genera that constitute the main body of fish in the studied river basin. The results of the VFFP method show which families (subfamilies) and genera are representative for the basin. Therefore, combining the TFFA and VFFP methods to analyze the composition of fish fauna can reflect the characteristics of fish fauna from different perspectives. The case study shows that the fish fauna of the Mekong River is a part of the fish fauna of Southeast Asia. Although it shows some similarities to the composition of South Asian fish fauna, it does not belong to the South Asian fish fauna as a whole, and is essentially different from the East Asian fish fauna. This study provides an objective, quantitative, and verifiable method for studying fish fauna.
鱼类区系研究不仅应着眼于鱼类组成以及研究区域和邻近区域鱼类组成的比较,还应探讨不同分类单元的起源和独特性以及属和种的更替。在本研究中,对植物区系存在方法的价值进行了修改,并将其重新命名为鱼类区系存在价值(VFFP)方法。细化并标准化了 VFFP 方法和传统鱼类区系分析(TFFA)方法的具体步骤。然后,将 VFFP 和 TFFA 方法应用于研究湄公河上游和中游的鱼类区系。结果表明,TFFA 方法反映了构成研究流域鱼类主体的科(亚科)和属。VFFP 方法的结果表明哪些科(亚科)和属是流域的代表。因此,结合 TFFA 和 VFFP 方法分析鱼类区系组成可以从不同角度反映鱼类区系的特征。案例研究表明,湄公河鱼类区系是东南亚鱼类区系的一部分。尽管它与南亚鱼类区系的组成有一些相似之处,但它并不属于整个南亚鱼类区系,与东亚鱼类区系在本质上也不同。本研究为鱼类区系研究提供了一种客观、定量和可验证的方法。
