Genome sequencing provides novel insights into diadromous migration adaptations in the roughskin sculpin, <i>Trachidermus fasciatus</i> (Scorpaeniformes, Cottidae).

ABSTRACT: The ecological opportunities presented by the invasion from marine to freshwater habitats are considered to be an important catalyst for the adaptive radiation of many fish taxa. The sculpins (family Cottidae) serve as a typical representative of such successful evolutionary radiation from marine to freshwater environments, and among which, several intermediate diadromous taxa that can adapt to both marine and freshwater habitats have been evolved. However, little is known about the genetic basis underlying the diadromous migration adaptations for these euryhaline sculpins. Here, we have constructed a high-quality chromosome-level genome of the Cottidae species roughskin sculpin (Trachidermus fasciatus) and made a comparative genomic analysis of the genomes from the closely related
