Genetic and geographical insights call for early conservation of Mae Hong Son's blue mahseer to prevent population crisis.

ABSTRACT: Ecosystems are being disrupted by climate change and habitat fragmentation, which affect species survival through altered mating, feeding, and migration patterns. Mae Hong Son Province, Thailand, harbors a unique hydrological network that supports rich freshwater fish biodiversity. Blue mahseer (Neolissochilus stracheyi), which is restricted to headwater streams in Mae Hong Son, is particularly sensitive to habitat disturbances and has experienced population decline. Despite their vulnerability to climate change and habitat fragmentation, information on the genetic diversity, population structure, and environmental drivers of their distribution remains limited. In this study, microsatellite genotyping and mitochondrial DNA displacement loop sequence analysis were used to assess the genetic
