Abstract

Objectives: European whitefish (Coregonus lavaretus L.) is a freshwater salmonid that inhabits cold regions of central and north Europe and Siberia. It is an important aquaculture species in Finland, selectively bred since 1999. The breeding programme has applied genomic selection that uses SNP markers and phenotypic data to improve traits such as growth, product quality, and fish health. Salmonids are known for chromosomal rearrangements, and the current C. lavaretus reference genome that is based on an individual from Switzerland may deviate from the Finnish one. Therefore, we have assembled a genome for the Finnish European whitefish. This allows us to better assess the genetic basis of fish traits and to enhance the accuracy of genomic selection.

Data description: The genome of European whitefish was sequenced using a combination of Illumina and PacBio technologies and assembled using wtbg2 and HiRise software. The assembly has a size of 2.94 Gb and comprises 6,706 scaffolds with the scaffold N50 of 1.36 Mb.

芬兰选择性育种计划中养殖欧洲白鱼的基因组组装。

目的：欧洲白鱼（Coregonus lavaretus L.）是一种淡水鲑鱼，生活在中欧和北欧以及西伯利亚的寒冷地区。它是芬兰重要的水产养殖品种，自1999年以来进行了选择性养殖。该育种计划应用了基因组选择，利用SNP标记和表型数据来改善诸如生长、产品质量和鱼类健康等性状。鲑鱼以染色体重排而闻名，目前基于瑞士个体的lavaretus c.l avaretus参考基因组可能会偏离芬兰的基因组。因此，我们已经组装了芬兰欧洲白鱼的基因组。这使我们能够更好地评估鱼类性状的遗传基础，并提高基因组选择的准确性。数据描述：使用Illumina和PacBio技术对欧洲白鱼基因组进行测序，并使用wtbg2和HiRise软件进行组装。该组件的大小为2.94 Gb，包含6706个支架，其中支架N50为1.36 Mb。
