Overview

Randomized trial investigates genetic diversity and population structure in Macrobrachium nipponense, suggesting implications for aquaculture and conservation.

Key Points

  • To assess the genetic diversity and population structure of Macrobrachium nipponense across multiple populations using microsatellite markers.
  • Used ten microsatellite markers to analyze 12 populations of Macrobrachium nipponense.
  • Measured genetic diversity metrics including observed and expected heterozygosity, and Shannon's diversity index.
  • Conducted population structure analysis and evaluated genetic differentiation among populations.
  • Detected 213 alleles across 342 individuals, with an average of 21.3 alleles per locus.
  • Observed heterozygosity ranged from 0.362 to 0.902 and expected heterozygosity from 0.581 to 0.925, indicating high genetic diversity.
  • Population structure analysis revealed weak genetic subdivision with most variation within populations (98% of genetic variation).
