Microsatellite Genotypes for Argentine Croaker Fish Across the Southwestern Atlantic

Microsatellite genotype data for the coastal fish Argentine croaker (Umbrina canosai) from three locations in the Southwestern Atlantic. The dataset includes raw genotypes for ten polymorphic loci and versions adjusted for null alleles, published in 2025. It was created by Davi M. Vasconcellos and used for a population genetics study on the species' resilience to overfishing.

Use Cases

• Assess population genetic structure based on microsatellite data from three distinct geographic regions.
• Estimate genetic diversity and connectivity for a commercially fished species mentioned in the description.
• Correct for null alleles in microsatellite data using the Oosterhout method described in the dataset.
• Conduct population analysis using genotype data formatted for Genepop and FSTAT software.

Strengths

• Data is provided in multiple processed forms: raw genotypes and versions adjusted for null alleles.
• Covers three distinct sampling locations spanning a significant portion of the species' range in the Southwestern Atlantic.
• Includes data from ten polymorphic microsatellite loci.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 29.7 KB, indicating a limited scope.
