Abstract
The giant freshwater prawn (GFP), Macrobrachium rosenbergii, is one of the largest freshwater shrimps in the world, being widely cultured because of its high economic value. In this study, complete mitogenomes of two GFP individuals from different selective breeding populations, ‘South Taihu No.2’ (ST) and ‘Shufeng’ (SF), were newly sequenced, compared with each other, and with those of other published Macrobrachium species. The total length is 15,767 bp (ST) and 15,766 bp (SF), including 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and one control region. The phylogenetic analyses based on whole mitogenome sequences suggest that ‘Shufeng’ has a slightly distant relationship with ‘South Taihu No.2’, with a pairwise genetic distance of 0.011. This study can provide a genetic background for the GFP selective breeding, and add significantly to the knowledgebase regarding crustacean biology and aquaculture as well.
