Whole-Genome Resequencing of 300 Coregonus ussuriensis Fish for Genetic Diversity Analysis

Heilongjiang Province, China, provides the source for whole-genome resequencing data from 300 individuals of the cold-water fish Coregonus ussuriensis. Author Tianqing Huang generated approximately 2.62 Tb of clean data, identifying 18,820,487 high-quality SNPs. The dataset was last updated on 2026-05-06.

Use Cases

• Conduct population genetic structure analysis based on the identification of five distinct genetic clusters.
• Assess genetic diversity and inbreeding levels based on reported heterozygosity (Ho), nucleotide diversity (Pi), and inbreeding coefficient values.
• Develop DNA fingerprinting systems for individual discrimination based on the core set of 138 SNP markers.
• Construct optimized core collections for breeding programs based on the methodology using Core Hunter software to retain allelic diversity.

Strengths

• Contains whole-genome resequencing data from 300 individuals, a substantial sample size for population-level analysis.
• Reports specific, high-quality metrics including 18,820,487 SNPs, an average sequencing depth of 10.28×, and a mapping rate of 99.02%.
• Includes derived analytical results such as genetic clusters, diversity indices, a DNA fingerprint marker set, and a core collection of 90 individuals.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for certain modeling tasks.
• Data may reflect geographic bias inherent to the single breeding population sampled in Heilongjiang Province.
