Abstract
The present study characterized the complete mitochondrial genome of Cynoscion acoupa, commonly referred to as the “pescada amarela”, being a member of the Sciaenidae family. C. acoupa are exploited for food consumption, and this causes a big impact in the populations. We used a NovaSeq Illumina sequencing to access the complete mitogenome of C. acoupa and perform a comparative investigation in molecular evolution. The mitogenome has 16,506pb, containing 13 protein-coding, 22tRNAs, and 2 rRNA genes. The average of the composition in the mitogenome was A: 26.56%, T: 29.46%, G: 33.26%, and C: 10.72%, with an AT content of 56.02%. Our phylogenetic analyses based on the 13 concatenated protein-coding genes of the mitogenome indicate that Cynoscion acoupa belongs to the family Sciaenidae and is positioned near the basal region of the phylogenetic tree, suggesting a shared ancestry among the analyzed taxa. These results confirm that the combined mitochondrial gene set serves as a reliable molecular marker for elucidating phylogenetic relationships within Sciaenidae.
