| Abstract: | Cyt b gene region of mitochondrial DNA(mtDNA) of Leiocassis crassilabris from Qiantang river was sequenced and compared with other sequences of Bagridae comprising of 9 species(1128 bp).Phylogenetic trees were developed by neighbour-joining(NJ),and unweighted pair group method with arithmetic mean(UPGMA).Based on the trees,L.crassilabris and cuttail bullhead Pseudobagrus truncatus were clustered into one clade,indicating that L.crassilabris shared a closer relationship with P.truncatus than the others. |
