Description and comparison of two economically important fish species mitogenomes: <i>Prochilodus argenteus</i> and <i>Prochilodus costatus</i> (Characiformes, Prochilodontidae)

Abstract

Prochilodus spp. are important Brazilian freshwater migratory fishes with substantial economic and ecological importance. Prochilodus argenteus and Prochilodus costatus are morphologically similar and a molecular species delimitation is impaired due to high degree of sequence identity among the available genetic markers. Here, the complete mitochondrial genome of P. argenteus and P. costatus and their comparison to the mitogenome of P. lineatus are described. The three species displayed a similar mtDNA annotation. A phylogenetic analysis was performed with other Characiformes species. The genus Prochilodus was recovered as a monophyletic group, as well as the family Prochilodontidae, both with high bootstrap probability.
