Abstract: The allotriploid grouper, Epinephelus fuscoguttatus ♀ × Epinephelus tukula ♂, is an economically valuable aquaculture species owing to its fast growth rate and desirable meat quality. Despite its many favorable traits, there is still a lack of records on allotriploid grouper mitochondrial genome. In this study, we determined and analyzed the complete mitochondrial genome of the triploid hybrid grouper Epinephelus fuscoguttatus ♀ × Epinephelus tukula ♂. The mitogenome was 16,610 bp in length and contains 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a control region. The order and composition of these genes were similar to other vertebrates. The overall base composition was 29.11% for A, 28.40% for C, 15.65% for G, and 26.84% for T, with a higher A + T content (55.95%). Phylogenetic analysis showed that the allotriploid grouper, Epinephelus fuscoguttatus ♀ × Epinephelus tukula ♂, was most closely related to Epinephelus fuscoguttatus . This study provides the first mitochondrial genome record of allotriploid grouper, which will facilitate future research on evolution and phylogeny of Epinephelidae.
