The complete mitochondrial genome of a new invader fish in France, the pink salmon Oncorhynchus gorbuscha (Walbaum, 1792) (Teleostei, Salmonidae)

Abstract

International audienceThe pink salmon Oncorhynchus gorbuscha (Teleostei, Salmonidae) is a North Pacific species. It arrived in Northern Europe through freshwater migration each odd year since 2017, creating management issues. In this study, we sequenced a complete mitochondrial genome for a pink salmon caught in the Bresle River (France) with a museum voucher. The sequence is 16,695 bp in length and is similar to previous mitogenomes published within this genus. Length heteroplasmy on the control region for this species was detected, as described in previous molecular studies. We tested several primers commonly used for metabarcoding studies on four markers (12S, 16S, COI and Cytb), and all allow the discrimination of this species. This mitogenome is a reference for molecular identification, for instance in like environmental DNA studies
