Threats [top]
| Major Threat(s): | There are three introduced cyprinids (Hemiculter leucisculus, Abbottina rivularis and Pseudorasbora parva) present at the site where Y. macrogaster was discovered (Dudgeon 2000); however it is not thought that these species prey on or compete with Y. macrogaster. There are several human settlements in close proximity to the site which may threaten the species (Kottelat and Chu 1988). |
