Outline of Final Research Achievements

The origins and current status of the unique freshwater fish fauna of Inle Lake, Myanmar, were investigated. During our four field surveys in 2014-2016, we collected 49 species belonging to 19 families from 68 sites around the lake. About 40% of them were non-indigenous species, including highly invasive ones; and two endemic species appear to have become extinct. Molecular phylogenetic analysis of the origins of endemic species (e.g., Cyprinus and Channa) provided insights into the formation of the fauna of the lake, including its ancient origin and interactions with the surrounding areas. The data on the specimens (e.g., collection sites, photographs, and DNA barcoding) are available via the FiMSEA web database.
