Any Additional Overall Comments to the Author	Scomber colias is a valuable marine resource, with a high impact on the fisheries of several countries on the west coast of the Atlantic Ocean and/or the Mediterranean Sea. This study reports the first genome assembly of Atlantic chub mackerel. This genome is timely and the assembly process is clearly describedis, which contribute to the effective conservation, management, and sustainable exploitation of S. colias species in the Anthropocene. I still have the following questions. The assembly effect of the genome does not seem to be particularly good. For example, the length of N50 length of scaffolds is not long enough. How many ploidy is this species? Do heterozygosity and repetition rate affect the assembly effect? It is suggested that the author can make a simple table to show the assembly effects within the Order Scombriformes. It is helpful for relevant researchers to make use of the genomic resources. Is "data validation" followed by the results section? And there is no subtitle in the result part. Is it required by this type of article?
