DNA barcoding of freshwater fishes from Brahmaputra River in Eastern Himalaya biodiversity hotspot.

ABSTRACT: The genetic diversity of freshwater fishes is still anonymous in several drainage systems in northeast India. Moreover, the comparative genetic analysis is largely sporadic to judge their actual diversity and true status. We generated 89 DNA barcodes of 40 morphologically identified fishes collected from two major tributaries of Brahmaputra River. The comparative study revealed that most of the species were clearly discriminated by their estimated genetic distances and monophyletic clustering in Bayesian (BA) tree. Considering the genetic divergence (2%) for species discrimination boundary, the high genetic diversity (2.36-10.73%) was detected in 11 species (Macrognathus pancalus, Channa punctata, Puntius terio, Bangana ariza, Garra arupi, Badis badis<
