Description  The northern snakehead Channa argus is widely distributed and extremely resistant tohypoxia; which is cultivated in China as an aquaculture species and has heritable albinobody colour populations. Here, two phenotypes of albino C. argus of “gray fin rays” and“gold fin rays.” were studied. The genetic diversity and molecular phylogenetics of C. arguswith different body colours and geographical distributions were investigated based ontheir nuclear ITS1-5.8S-ITS2 sequences. The ITS1-5.8S-ITS2 sequences of the C. arguswere conservative, with 1/1000 of mutation sites and 0.000-0.014 genetic distance, whichshowed that the studied phenotypes of C. argus belong to the same species. The intraspecificvariation sites of the studied sequences showed that it was mainly nuclear transformation;with the sequences from albino C. argus with “gold fin rays” individuals having more variationsites than “gray fin rays” individuals. The difference in the geographical distributions ofC. argus were distinguished in phylogenetic relationship studies, which supported thatnuclear ITS1-5.8S-ITS2 sequences can be used to study molecular phylogeography
