Reference genome of the Woolly Sculpin, Clinocottus analis

Abstract

Sculpins (Family Cottidae) are generally cold-temperate intertidal reef fishes most commonly found in the North Pacific. As part of the California Conservation Genomics Project (CCGP), we sequenced the genome of the Woolly Sculpin, Clinocottus analis, to establish a genomic model for understanding phylogeographic structure of inshore marine taxa along the California coast. These patterns, in turn, should further inform the design of marine protected areas using dispersal models based on genomic data. The small genome of C. analis is typical of marine fishes at less than 1 Gb (genome size = 538 Mb), and our assembly is near-chromosome level (contig N50 = 9.1 Mb, scaffold N50 = 21 Mb, BUSCO completeness = 97.9%). Within the context of the CCGP, the Woolly Sculpin genome will be used as a reference for future whole-genome resequencing projects aimed at enhancing our knowledge of the population structure of the species, and efficacy of marine protected areas across the state.
